Ikebana: Styles, Schools, Kenzan, Vases and Supplies Guide

Ikebana (生け花 / いけばな) is the Japanese art of flower arrangement: cutting branches, leaves and flowers, shaping them and setting them in a vessel so they take on a new beauty in a new place.^[16][17] If you have seen a few stems standing in a shallow bowl on a spiky metal pad, that pad is a kenzan — the Japanese “flower frog”. This guide explains what ikebana means, its history, the main styles and rules, how Ikenobo, Sogetsu and Ohara differ, and the supplies you need (kenzan, ikebana vases and scissors), with sizes and 2026 prices from Japanese shops.

What Is Ikebana? Meaning, Definition, Kanji and Pronunciation

Ikebana definition and etymology: written in kanji as 生け花, the “ike” in ikebana comes from the verb ikeru (いける), “to keep alive”, and bana/hana means flowers. Kotobank defines the word as cutting branches and flowers, shaping them and placing them in a vessel — and also the technique itself. Its earliest recorded use is in the Sendensho (仙伝抄) of 1445.^[16] The wider discipline is called kado (華道 / 花道, “the way of flowers”), a term that grew up in the Edo period when the self-cultivation side of the practice was stressed; synonyms are 挿花 (soka).^[18][19] Ikebana pronunciation (how to pronounce it) in English is roughly “ee-keh-bah-nah”. School names often end in -ryu (流, “school”), as in Sogetsu-ryu and Ohara-ryu.

Ikenobo describes ikebana as arranging cut plants so they gain new beauty in a new setting, and it values buds and withered leaves as much as open flowers. Its 16th-century teacher Senno Ikenobo is quoted as saying that “not only beautiful flowers but also buds and withered flowers have life, and each has its own beauty”.^[17][20] The Japan National Tourism Organization (JNTO) calls ikebana “the sum of many pieces — the flowers, plants, vase and space”, favoring simplicity and minimalism — those four are the basic elements of an arrangement, explained in the sections below.^[21][22]

So when people ask “what is the Japanese art of flower arrangement called?” — the answer is ikebana (seven letters, the usual crossword answer), or kado for the discipline as a whole.

Ikebana History: Where It Came From

Ikenobo traces ikebana to three roots: flowers enjoyed for their beauty, yorishiro (objects that call down divine spirits, such as the kadomatsu pine at New Year) and flower offerings on Buddhist altars after Buddhism reached Japan in the 6th century. Its beginner guide says ikebana began with priests’ offerings to the Buddha.^[23][24] A set of three altar objects — vase, incense burner and candle holder (mitsugusoku) — spread in the Kamakura and Nanbokucho periods, and in the Muromachi period, room decoration with imported Chinese vases led to the upright tatehana.^[23][25]

• 1462: the diary Hekizan nichiroku records Senkei Ikenobo, a priest of Rokkakudo temple in Kyoto, arranging flowers for a warrior to wide praise. Ikenobo dates its start to this record, and Kotobank calls Senkei the school’s founder.^[23][26]
• Late 15th century: Kao irai no Kadensho (1486–1499) is believed to be the oldest surviving ikebana manuscript.^[23]
• 16th century: Senno Ikenobo set down a full theory — philosophy as well as technique — in the Senno Kuden; surviving copies date from the 1530s–40s. Yasunari Kawabata quoted it in his Nobel lecture.^[23][27]
• 1594: Senko Ikenobo I made a large rikka for Toyotomi Hideyoshi’s visit to Maeda Toshiie’s residence.^[23]
• Early Edo: Senko Ikenobo II perfected rikka; in the mid-Edo period the simpler seika/shoka spread among townspeople and many new schools appeared, their heads taking the title iemoto.^[23][28][29]
• 1692: Ikenobo disciples made rikka about 9 m (30 ft) tall for the ceremony marking the Great Buddha restoration at Todai-ji.^[23]
• Meiji period: as Japanese homes westernized, nageire and moribana (Unshin Ohara’s low-bowl style) arose; Ikenobo began teaching at a Kyoto girls’ school in 1879, and more women took up ikebana.^[23][30][31]
• 1927: Sofu Teshigahara founded the Sogetsu school in Tokyo; postwar “avant-garde” ikebana was led by Sofu, Nakayama Bunpo and Ohara Houn.^[32][29]
• 1956: Ikebana International was founded by Ellen Gordon Allen; 1966: the Japan Ikebana Art Association was formed, with Sofu Teshigahara as first chairman.^[33][34][35]
• October 2026: Japan’s Council for Cultural Affairs recommended that rikka be designated an Important Intangible Cultural Property, with Headmaster Sen’ei Ikenobo recognized as its holder (popularly, a “Living National Treasure”).^[36][37]

Ikebana’s link with China is in the vessels: it grew out of placing flowers in imported Chinese vases (karamono), and Chinese bronze and celadon vases arrived from the mid-Kamakura period.^[23][25]

Ikebana Styles: Rikka, Shoka, Moribana, Nageire and Free Style

Each school has its own names, but the Nipponica encyclopedia groups ikebana styles into six: rikka, seika, nageire, bunjinbana (literati), moribana and jiyuka.^[29]

Sources: ^{[38][39][28][19][31][40][41][42][30][29]}. A few details by school: Ikenobo’s modern rikka shimputai (1999) and shoka shimputai (1977) have freer forms than the classic shofutai.^[38] Ohara teaches upright, slanting and water-viewing moribana, landscape moribana, and heika (its name for nageire-type arrangements) in upright and slanting forms without a kenzan.^[43] “Free style” is used differently: for Ikenobo, jiyuka is the postwar name for its nageire and moribana styles, while Britannica (in Kotobank) treats moribana itself as also called jiyuka.^[23][31] Ikenobo’s media page sums up the rules: rikka and shoka can have rules on materials and combinations, and jiyuka has none.^[42]

Ikebana Principles and Rules: Heaven, Earth and Man

The best-known ikebana rule is the three main lines. In Ikenobo shoka they are shin, soe and tai, “likened to three poles or functions (heaven, earth and mankind)”.^[38] In seika generally the three lines are called ten-chi-jin (天・地・人, heaven-earth-man). The Nipponica encyclopedia notes that the names of the branches differ from school to school, but three main branches usually form an uneven triangle.^[19][29][44] Sogetsu’s first textbook starts from a basic upright form called risshin-kei; for each school’s own names and angles, follow that school’s textbook.^[45]

• Asymmetry and a single stem point: shoka shows the plant rising from one point at the water line in a “く”-shaped triangle.^[19]
• Space (ma): Ohara calls the space between plants ma (間).^[43]
• Subtraction, not addition: Ikenobo’s beginner guide contrasts Western flower arrangement, an “aesthetics of addition” that fills space with many flowers, with ikebana’s “aesthetics of subtraction” — as few flowers and leaves as possible, with empty space valued for its own beauty.^[24]
• Every stage of the plant: buds and withered leaves are part of the arrangement.^[20]
• Any material (Sogetsu): Sogetsu’s creed is “anytime, anywhere, by anyone”, with any material — so Sogetsu ikebana welcomes using unconventional materials, and Sogetsu freestyle has no fixed form.^[46][47]

Ikebana basics step by step (a short tutorial on the method) — simple ikebana rules for beginners, from Ikenobo’s and Nipponica’s how-to pages: cut branches on a slant (split thick ones) and grasses straight across; push each stem straight down onto the kenzan, then tilt it to the angle you want; and keep the water just above the pins.^[48][29]

Ikebana Schools: Ikenobo vs Sogetsu vs Ohara

There is no single count of ikebana schools. The Japan Ikebana Art Association lists 232 member schools and 3,250 members as of December 31, 2025; Ohara’s beginners page says the total is “said to be over 400”, and Nipponica estimates 2,000 or more, of which 600–700 are active.^[35][43][29] Ikenobo, Ohara and Sogetsu are commonly called the “big three”.^[49][21]

Sources: ^{[17][20][32][50][51][52][46][30][53][54]}.

Ikenobo

Ikenobo, which Nipponica calls the oldest school, is based beside Rokkakudo (Choho-ji) temple in central Kyoto, a 3-minute walk from exit 5 of Karasuma Oike station. The name means “the priest’s hut (bo) by the pond (ike)”, and Ikenobo headmasters have served as the temple’s head priests.^[55][56][20] The school holds public exhibitions — Hatsuike on January 5, a spring exhibition in April and an autumn exhibition in November — and opened Ikenobo Junior College in 1952, a San Francisco office in 1968, and its Kyoto headquarters building with the Ikebana History Museum in 1977.^[57][23] Classes at the Kyoto headquarters are for students who already hold at least four Ikenobo diplomas.^[57]

Sogetsu

Sofu Teshigahara, the ikebana artist and master (iemoto, headmaster) who was son of the ikebana teacher Wafu Teshigahara, founded Sogetsu in 1927 and held its first exhibition at Senbikiya in Ginza in 1928. TIME called him the “Picasso of flowers”; France gave him the Order of Arts and Letters (1960) and the Legion of Honor (1961).^[50][51][47] The headmasters since are Kasumi (1979), Hiroshi (1980) and Akane Teshigahara (2001).^[47][58] Sogetsu’s first overseas class was held in Tennessee in 1939, and the school now has about 120 overseas branches and study groups in 38 countries and regions.^[51][46]

Ohara

Unshin Ohara (1861–1916, per the Ohara School) was born in Matsue to a family of potters and worked as a sculptor in Osaka. He designed the shallow suiban and bowls for Western flowers and created moribana — which, the school says, “has now spread to every school”.^[30] The fifth headmaster, Hiroki Ohara, succeeded in 1995 at age six.^[30] The Japan Ikebana Art Association notes that Ohara was among the first schools to hold group lessons and to open teaching posts to women.^[59]

Ikebana International

Ikebana International (I.I.) was founded in 1956 by Ellen Gordon Allen, an American, under the motto “Friendship through Flowers”. It is a volunteer-run nonprofit, endorses no single school and does not give lessons; individual dues are ¥6,000 a year, and members receive three issues of its magazine.^[33][60] As of June 30, 2026 it had 6,524 members in 138 chapters.^[61] Its chapter list shows more than 50 US chapters across states such as California, Hawaii, New York, Texas and Washington; the Washington, D.C. chapter is Chapter #1.^[62][63] Its six “Supreme Adviser” schools are Ichiyo, Ikenobo, Misho, Ohara, Saga Goryu and Sogetsu.^[62]

Ikebana Kenzan (Flower Frog): What It Is and How to Use It

A kenzan (剣山, pronounced “ken-zahn”; the translation is literally “mountain of swords”) is a heavy metal base set with upward-pointing pins; you press stems onto the pins to hold them at an angle. It is mainly used for moribana in a shallow vessel. In English it is called a flower frog, pin frog or pin holder — Ikenobo’s own English flyer says “pin frog”.^{[64][48][65][66]} The general Japanese term for any stem holder is hanadome (花留); before the kenzan, arrangers used straw bundles, forked twigs and the shippo grid holder.^[67][68]

Who invented the kenzan? Nobody is credited. Ikenobo’s shop says the inventor is unknown because many people claimed it; kenzan came into use between the late Meiji and early Taisho periods, and Adachi Choka is recorded as working to improve it around 1914.^[68][67]

How do flower frogs work? Kenzan vs flower frog vs floral foam

What are flower frogs used for? They hold stems upright or at an angle in a shallow vessel, where the stems could not stand on their own. “Flower frog” is the broad English term (its definition covers any stem holder), and a kenzan is the Japanese pin type, with sharp needles (pins or spikes) set in a needle base. Against floral foam (often sold as Oasis), Ikenobo points out that a metal kenzan can be washed and reused, while foam is thrown away after use.^[48] Ikenobo’s shop still sells water-absorbing foam as an easy holder for moribana, bouquets and decorative arrangements.^[68] Flower frog alternatives for ikebana without a kenzan: a tall nageire vase, floral foam, or a shippo, which Ohara teaches as a non-kenzan holder.^[43]

Materials: brass, lead and plastic

• Metal kenzan: a lead base (鉛) with brass pins (真鍮) is the usual build in retail specs. Brass pins darken over time and, being soft, can bend after years of use; stainless pins resist rust.^{[9][1][69][48]}
• Plastic kenzan: clear, cheaper and lighter — Ikenobo suggests them for see-through glass vases — but they can tip over and hard branches can break the pins. Some have a suction cup.^[48][66][5]

Pin types and shapes

Ikenobo’s shop sells three pin layouts: for branches (木もの, the standard, about 370 pins), for grasses and flowers (草もの, denser, about 610 pins) and dual-purpose (stronger center pins with finer pins around them).^[68] Ishizaki Kenzan’s extra-dense types pack in about 1.2–2 times more, thinner pins so thin stems hold.^[70] Shapes are round (the standard, and the main shape for rikka and shoka), square, boat and oval; for free style, match the kenzan to the vessel.^[68] A kenzan ring (蛇の目, janome) has a built-in water cup around the pins.^[10]

Kenzan sizes and prices

Kenzan sizes are given as a number (号): the number is the overall diameter in centimeters, not the pin area.^[68]

Kadosha prices are tax-in on Ikenobo’s group shop; Ishizaki prices are tax-in at ASKUL or Toranote. Kadosha describes its kenzan as hand-made one by one with a thick lead base and brass pins it calls “strong and hard to break” — that is the shop’s claim.^[1] Ishizaki Kenzan, a maker in Sanjo, Niigata, says it does not take orders from overseas and points overseas buyers to a Japanese trading company.^[71][69]

How to use a kenzan

1. Set the kenzan in the vessel and pour water to just above the pins. Ikenobo’s shop suggests a kenzan sitting about 1.5 cm (0.6 in) below the vessel rim; its central training institute now teaches 2 cm.^[48][68]
2. Cut branches on a slant and grasses flat, then push each stem straight down onto the pins before tilting it to the angle you want.^[29][48]
3. For stems too thin for the pins, bundle several together or insert them inside a short, thick stem; a splint, wrapped paper or a twig core also works for hollow stems.^[48][29]
4. Steady the kenzan with your hand if it slides, and put a rubber guard or a cloth under it so it doesn’t scratch the vessel.^[48][66]
5. A black kenzan is less visible on dark stones; kenzan with screw holes can take feet sold separately.^[68][1]

Cleaning and straightening the pins

Rinse the kenzan and clear debris from the pin roots with a kenzan brush (剣山ぼうき, the usual kenzan cleaner) or a bamboo skewer, then dry it and store it out of children’s reach.^[69][48] Straighten bent pins with a kenzan straightener (剣山直し / 剣山起こし): slip its hollow end over the pin and ease it upright; many have a pick end for cleaning.^[48][72] Kadosha’s large brass straightener is ¥2,200, and Toyama Hamono sells an iron one (5.5 × 70 mm, about 10 g) for ¥900 including domestic shipping.^[73][72] Ishizaki takes back old kenzan free of charge if the sender pays shipping.^[69]

Ikebana Vases: Suiban, Usubata and Nageire Vases

Ikebana vessels (花器, kaki) come in pottery, porcelain, glass, wood, bamboo, copper, iron, stainless steel and acrylic; Kiyomizu, Shigaraki, Banko and Arita are well-known pottery areas, and copper vessels are the classic choice for traditional ikebana.^[74] Shapes include cylinders, jars, suiban and deep bowls; Kotobank adds the usubata, the hanging boat (tsuribune), shishiguchi, wide-mouth and narrow-mouth vases.^[74][25]

• Suiban (水盤): a wide, shallow ikebana bowl (sometimes sold as an ikebana plate, tray or dish) — the vessel where a kenzan is most useful. Ikenobo recommends beginners start with a plain, single-color round suiban.^[48][66]
• Usubata (薄端): a thin metal vase with a removable, dish-shaped top on a jar-shaped body, used in Ikenobo and Koryu.^[75]
• Nageire vase: any tall jar, vase or basket for “thrown-in” arrangements without a kenzan.^[41][40]

Which vessel for which style (Ikenobo): rikka in deep bowls; shoka in cylinders, suiban or wall-hung vessels; jiyuka has no rules.^[74] Typical prices on October 31, 2026 (tax-in): Daikakuji’s Saga Goryu shop lists a 30 cm (11.8 in) round suiban at ¥6,600, a 45 × 31 cm oval at ¥8,140 and a Banko-ware suiban at ¥5,800; Takaoka copperware suibans that come with a kenzan run ¥6,292–¥8,250, and Shigaraki suibans ¥14,300.^[76][77][78] Takaoka copper usubata listings on Kakaku.com run from about ¥47,800 to ¥290,800.^[79] For other Japanese pottery, see our Japanese ceramics guide.

Ikebana Scissors (Hasami)

Ikebana scissors (花鋏, hana-basami) cut flowers and small branches. Ikenobo uses the warabite (蕨手) shape — handles curled like a young fern frond.^[80][81][82] Choose scissors whose blades stick out of your closed fist; Ikenobo gives typical lengths of 5–5.5 sun for women and 6–6.5 sun for men (1 sun is about 3 cm / 1.2 in). They come in black (黒打) or silver (白打) finish; carbon steel is standard and stainless resists rust.^[81][66] One piece of ikebana etiquette: don’t lend your scissors or ask to borrow someone else’s.^[81]

Kadosha also sharpens right-handed scissors for ¥2,420, and its beginner range includes an ikebana starter set (いけばなはじめてセット) for ¥8,800.^[11][12] Sakagen in Sanjo, Niigata makes a range of ikebana scissors, including left-handed 165 mm models.^[83] For more Japanese scissors, see our Japanese scissors brands guide.

Ikebana Flowers by Season

Ikenobo says there are basically no forbidden flowers in ikebana — just think about the occasion (for example, avoid strong scents where people eat).^[42]

• Spring: cherry, tulip, rose; irises such as kakitsubata from about May.
• Summer: hydrangea, sunflower, lotus, gladiolus, lisianthus, anthurium, nadeshiko (pinks).
• Autumn: cosmos, susuki grass, burnet, chrysanthemum (for Choyo on September 9).
• Winter: camellia, poinsettia, holly, ornamental kale, senryo, nanten and plum, “the first of a hundred flowers”.^[42]
• New Year: pine, ornamental kale, senryo, nanten, plum, chrysanthemum, orchids and narcissus.^[84]

Because there are basically no forbidden flowers, roses, lilies, dahlias, ranunculus and orchids can all be used — ikebana is about line and space, not a fixed flower list.

Ikebana Classes in Japan (Kyoto and Tokyo)

• Ikenobo, Kyoto: a trial lesson (a two-hour workshop) for visitors on Thursdays 13:30–15:30 (except holidays), ¥7,000 per person as of October 2026, booked by email in English or Chinese for 2–10 people. You meet at the Rokkakudo gate, tour the temple and make a jiyuka arrangement; vases, pin frog and scissors are lent and you take the flowers home. Cancellations within 2 days cost ¥3,000.^[65] An older flyer lists ¥6,000, so check the page before booking.^[85]
• Sogetsu, Tokyo (Akasaka): the International Class is taught in English on Mondays 10:30–12:30; a first trial lesson is ¥6,000 including two bunches of material and tax. Book at least 5 days ahead — several November dates were already full on October 31.^[86][87] The Iemoto Class is taught in Japanese with an English-speaking assistant (trial ¥6,000); private group demonstrations start at ¥120,000.^[88][89]
• Elsewhere: JNTO says beginner classes can be found in most major cities.^[22] For online or local classes in the US, look up your nearest Ikebana International chapter or a school’s US branch.^[62]

Rokkakudo itself, the “birthplace of ikebana”, is temple No. 18 on the Saigoku 33 Kannon pilgrimage and has a hexagonal “navel stone” said to mark the center of Kyoto.^[56][90][91]

Ikebana vs Bonsai vs Western Flower Arranging

JNTO describes bonsai as “the art of producing small trees in containers” that mimic full-size trees, while ikebana is a “temporary art” of flowers, plants, vase and space.^[21] Against Western flower arranging, Ikenobo’s contrast is addition versus subtraction, and the reusable kenzan versus disposable foam.^[24][48] For bonsai pots and tools from Japan, see our bonsai supplies guide.

How to Buy Ikebana Supplies, Tools, Equipment and Accessories from Japan

1. Search in Japanese. Kenzan is 剣山, a suiban 水盤, ikebana vases 花器, scissors 花鋏, a kenzan straightener 剣山直し, and an ikebana kit 生け花 セット. Add the size (丸7号, 9cm).
2. Check the specs: diameter, pin type (木もの / 草もの), pin material (真鍮 brass or ステンレス stainless) and the weight.
3. Mind the weight. A lead-based kenzan weighs 318 g to 1.5 kg (11 oz to 3.3 lb), and a suiban adds both weight and box volume. International shipping is charged on the greater of actual and volumetric weight, so a suiban with a kenzan inside one box is usually cheaper than two parcels — get a quote first.
4. Use LinkBuy for Japanese ikebana shops that don’t ship abroad. Ikenobo’s headquarters says its supplies can also be bought from abroad by credit card after contacting its store, so compare both routes.^[57]
5. Before it ships: ceramic suiban are fragile. Add package reinforcement (from ¥100; a box change and outer padding cost extra), or unboxing photos (¥500 / ¥700) to check the vessel at the Tokyo warehouse.
