Japanese Eyewear From Japan (2026): Sabae Frames, What Used 999.9 and Masunaga Actually Cost — and the Cheap and Cheapest Way to Buy Them

TL;DR

Japanese frames are made in one small city, sold at Japanese retail prices at home, and
resold secondhand at a fraction of that — and a frame is one of the few high-value things
you can import that weighs almost nothing. The catch is not customs. It is that half the
listings include prescription lenses you are going to throw away.

• Real prices, checked on 4 September 2026 — an unused 999.9
  (Four Nines) S-702T at ¥5,000 (US$34.50), a titanium S-240T at
  ¥8,700 (US$60.03), a Masunaga KOKI DX at ¥5,380
  (US$37.12), a Kaneko Optical frame at ¥9,500
  (US$65.55).^[6]
• Sabae, in Fukui Prefecture, is the industry. The overwhelming majority of
  Japanese-made frames come out of one town, including the ones sold under designer
  labels.^[1]
• Buy the frame, not the glasses. A listing marked 度入り
  includes someone else’s prescription lenses. You pay for them and your optician removes them.
  度なし or フレームのみ is the cheaper, cleaner buy.
• The numbers on the temple are a universal standard.
  52□15-135 means a 52 mm lens, a 15 mm bridge and 135 mm arms —
  compare them to a frame you already own and you can size a used frame from overseas with
  confidence.
• Weight is the whole shipping story. A titanium frame is 15–25 g;
  even boxed with a hard case it sits in the cheapest band, which makes eyewear one of the best
  things to add to a consolidated parcel.

As of September 2026, the interesting price is not new Japanese eyewear — a
current 999.9 at a Japanese optician is a full-price purchase like anywhere else. It is the
domestic secondhand market, where frames that were ¥40,000–¥60,000 new circulate
at a fifth of that, and where discontinued Sabae references have a liquid market that does not
exist anywhere else.

Why Sabae

Fukui Prefecture’s eyewear industry started in the early 1900s as winter work for farming
households and ended up as a manufacturing cluster that supplies most of Japan’s domestic frame
production, and a great deal of the world’s titanium eyewear.^[1]
The practical consequence for a buyer is that “made in Sabae” is a manufacturing claim, not a
brand: it appears on frames from the famous houses and on frames from opticians nobody outside
Japan has heard of, and the second group is where the value is.

The One Thing That Decides the Price: 度入り

Japanese listings are explicit about whether a frame is carrying lenses, and the vocabulary
is short:

• 度入り — prescription lenses fitted. Someone else’s prescription. You
  will pay for them and then pay again to have them replaced.
• 度なし / 伊達メガネ — plano lenses, no correction. Fine as
  a placeholder; your optician will still swap them.
• フレームのみ / 本体のみ — frame only. Usually the cheapest
  per unit of frame.
• 純正ケース付 — comes with the maker’s own case. Nice, and it doubles
  the parcel’s volume — which matters, because shipping is billed on the greater of weight
  and volume.

Two of the 999.9 frames priced above — the S-127T at ¥13,000 and the S-916T at
¥13,200 — were both 度入り. The unused S-702T at ¥5,000 was not.
That is most of the price difference right there, and none of it is value you keep.

Sizing a frame you cannot try on

Every frame carries three numbers, usually inside the left arm: lens width, bridge width and
temple length, written like 52□15-135. One of the Masunaga listings above prints
exactly that string in its title. Measure the frame you currently wear, compare the three
numbers, and the guesswork mostly disappears. Add the sixth measurement your optician needs
— your pupillary distance — when you take the frame in for lenses; that is measured
locally, not bought from Japan.

Condition Words That Matter on a Used Frame

• 美品 / 超美品 — excellent condition. On frames this
  usually means no visible plating loss and straight arms.
• 未使用 — unused. Common in this category because people buy frames and
  never have lenses fitted.
• 歪み — warped or twisted. Adjustable by an optician on titanium, harder
  on acetate that has been heat-deformed.
• 鼻パッド — nose pads. A perishable part; assume you are replacing them
  and that this is a ¥500 job at home.
• ネジ — screws. Missing hinge screws are cheap to fix but a sign of how
  the frame was stored.

Because a frame is small and photographs badly, this is a strong category for asking the
proxy to take unboxing photographs before the parcel leaves Japan — the hinge, the inside
of the arm where the reference and size are stamped, and the plating around the nose bridge.
We have written up three real cases where that check caught a wrong item,
and eyewear has exactly the failure mode those cases show: the listing photo is of a similar
frame, not the frame.

Money: Fees, Weight and Duty

• Japanese consumption tax (10%) is already in the listed
  price.^[2] The tax-free counter tourists use does not apply to
  mail order.
• The proxy’s service fee is a flat ¥300 per order on Rakuten, Mercari,
  Suruga-ya and Amazon Japan; Yahoo! Auctions is 3% of the winning bid, between ¥200 and
  ¥300. On a ¥4,800 frame that is about 6%, and it does not scale — the same
  ¥300 buys a ¥13,200 one.
• Shipping is billed on chargeable weight: the greater of actual weight and
  volume divided by 5,000. A frame is 15–30 g. Even in a rigid case it is the cheapest
  band, which makes eyewear the ideal thing to add to a box you were shipping anyway.
• Import duty and tax at your border. The United States withdrew its US$800
  de minimis exemption on 29 August 2025^[3], and the EU applies a
  temporary flat fee to low-value imports with normal duty and VAT above
  it.^[4] Frames are ordinary dutiable goods; note that
  prescription eyewear is regulated differently in some countries, which is one more
  reason to import the frame and have lenses fitted at home.

Worked example

The unused Sabae-made FIGARO frame at ¥4,800 was a Yahoo! Auctions lot, so the fee is 3%
of the bid — ¥200 at that price. Total first payment about ¥5,000, or roughly
US$34. Add it to a parcel you were already sending and the marginal freight is close to nothing.
Compare that with a comparable Japanese-made titanium frame at a Western optician and the
arithmetic is not close — but you are buying a frame, and the lenses are still a local
bill.

Step-by-Step: Buying Japanese Eyewear From Overseas

1. Step 1 — Measure the frame you already wear. Write down the three
   numbers from the arm. This is the step people skip and then regret.
2. Step 2 — Search in Japanese, by reference where you can.
   999.9 メガネフレーム, 鯖江 メガネ フレーム,
   増永眼鏡. The 999.9 search is here, the
   Sabae frame search here, and the
   Masunaga search here.
3. Step 3 — Filter out 度入り unless you want it. If the
   title or the description says lenses are fitted, mentally deduct the cost of removing them.
4. Step 4 — Check the listing is a frame, not an accessory. This
   category is unusually full of cases, cloths, coupons and lens-only listings priced like frames.
   Read the item name to the end.
5. Step 5 — Order through a proxy and ask for photos. Japanese
   flea-market and auction sellers ship domestically only. Request the hinge and the stamped
   reference on the inside of the arm before ship-out.
6. Step 6 — Consolidate, then take it to an optician. Frames weigh
   nothing, so batch them with the rest of your order — check the numbers in the
   shipping calculator — and budget separately for
   lenses at home, which is where the second half of the cost lives.

Frequently Asked Questions

Can my optician fit lenses to a frame bought from Japan?

In general yes — frames are a standard product and Japanese ones are made to the same
measurements as everyone else’s. Call ahead if the frame is rimless or half-rim, because those
need drilling or a groove and some shops decline to work on frames they did not supply.

Is Japanese-made eyewear actually better?

“Made in Sabae” tells you where it was manufactured, not that it is good. What it does
reliably signal is titanium work, hinge quality and finishing at a standard the town has been
producing for a century. Plenty of luxury-labelled frames are made there too, at prices that do
not reflect the manufacturing cost.

Are used frames from Japan hygienic?

Frames are washable and the parts that touch skin — nose pads and temple tips —
are replaceable consumables. Replace them; it is inexpensive and your optician does it while
fitting the lenses.

How do I avoid buying a case instead of a frame?

Read the whole item title. In this category メガネケース (glasses case),
レンズのみ (lenses only) and even discount coupons are listed at frame-like
prices. The clue is usually a price that is far below the rest of the search results.

What about sunglasses?

Same market, same rules, and no lens problem — sunglasses arrive usable. The 999.9
feelsun line ran ¥8,000–¥10,300 on the day this was written, which is
roughly what a used clear-lens frame from the same brand costs.

The Short Version

Measure your current frame, search Sabae and the domestic secondhand market rather than the
brand’s international site, avoid 度入り unless you want someone else’s
prescription, and add the frame to a parcel you were shipping anyway — it weighs nothing.
