How to Choose Japanese Masks: 3 Things to Check & Packaging Glossary
Japanese mask product pages list the size, number of masks, packaging type and country of origin. Knowing these few terms makes it much harder to buy the wrong one:
- Pick the use and size first: pleated boxes suit everyday work or school, 3D masks give a roomier fit, a moisturising mask helps when your throat is dry at night, and kids’ sizes are for children. Japanese mask sizes are usually ふつう (regular), 小さめ (smaller) and こども用 (kids); actual dimensions vary by brand, so check the cm measurements on the product page before ordering.
- Read the packaging labels: look for 日本製 (made in Japan), JIS T 9001 with a 規格適合番号 (conformity number) and 個包装 (individually wrapped). Claims such as 99％カット are the manufacturer’s own test results and are not the same as the JIS standard, so go by the JIS label and conformity number when comparing.
- Compare the price per mask and reach ¥5,000: Rakuten masks are mostly sold in boxes or multi-bag sets, so divide the total price by the number of masks. The ¥500 coupon needs a single order of ¥5,000 or more, so if one item falls short, check out several items together.
Japanese mask packaging glossary
| Japanese | Meaning | Buying tip |
|---|---|---|
| ふつう | Regular size | Standard adult size; actual size differs slightly by brand |
| 小さめ | Smaller size | Suits women or smaller faces |
| 大きめ／ゆったり | Larger size | Suits larger faces or a looser fit |
| こども用 | For kids | Check the age range and size in cm |
| 日本製 | Made in Japan | Japanese brands are not always made in Japan; go by the package and product page |
| 個包装 | Individually wrapped | Each mask is wrapped separately, handy for a bag or school bag |
| プリーツ | Pleated | Folded flat and easy to store |
| 立体 | 3D | Contoured to the face, with more room at the mouth and nose |
| 就寝用 | For sleeping | Worn overnight; common with wet masks |
| ぬれマスク | Wet mask | Comes with a moist filter to keep the throat moist |
| 送料無料 | Free shipping (within Japan) | Means the store pays domestic shipping; go by the product page |
Japanese Mask Types Compared: Pleated, 3D, Wet and Kids’ Masks
Japanese masks fall into four main types — pleated, 3D, wet and kids’ — suited to everyday restocking, a less clingy fit, dry throats during sleep and children respectively. The table uses this guide’s 6 picks as examples.
| Type | Shape and features | Best for | Picks in this guide | What to check |
|---|---|---|---|---|
| Pleated | Folded flat and pulled open to fit the face; usually big boxes with a lower price per mask | Everyday work or school, home restocking, stocking up | 1. Unicharm, 2. Iris Ohyama Nano Air Mask | Fit depends on face shape; compare regular and smaller sizes |
| 3D | Pre-shaped with more room at the mouth and nose; usually packed in separate bags | A less clingy fit, a face-slimming look, carrying in a bag | 3. Kowa Sanjigen, 4. be-style | 3D masks usually cost more per mask than pleated: in this guide 3D picks run S$0.40 to S$0.68 each, pleated picks S$0.22 to S$0.33 |
| Wet mask | The mask comes with a moist filter that keeps the throat moist; usually labelled for sleeping | Dry throat while sleeping | 5. Nodonuru Wet Mask | Contains moisturising ingredients; about S$1.16 per set |
| Kids’ mask | Smaller size, usually labelled with an age range or cm size | Primary-school children | 6. Bihou Kids’ Mask | Children’s faces vary, so check the cm size on the product page (e.g. 80 × 132mm) |
Not sure which suits you? Start with a bag-packed 3D mask or a single box of pleated masks, then order more boxes together once you know it fits, to reach the ¥5,000 coupon minimum.

- Long hours of wear: choose Unicharm — the wide ear loops are easier on the ears, and the 3-box set already clears the ¥5,000 minimum, so you can use the coupon straight away.
- A 3D mask that is easy to carry: choose Kowa Sanjigen — 7 masks per bag, easy to split between bags; one pack is ¥3,450, so 2 packs at ¥6,900 clear the coupon minimum.
- Stocking up for the whole family at the lowest price per mask: choose Iris Ohyama — the lowest price per mask of the three, with JIS T 9001 labelling to check; 4 boxes of 50 at ¥5,520 clear the coupon minimum.
- Other needs: pick 4 (be-style) for a small-face look, 6 (Bihou) for children, or 5 (Nodonuru) if your throat gets dry while sleeping.
All three are everyday masks, not medical masks. Prices and stock change at any time, so go by the latest Rakuten product page.

Where to Buy Japanese Masks: What You Need to Know
All 6 picks are sold by stores on Rakuten Japan Marketplace: Rakuten 24, Iris Ohyama Official Rakuten Store, Nekogoro Daily Goods & Cosmetics Rakuten Store, Ariana Shop, Tweedia Rakuten Store and Bihou. Most Rakuten Ichiba stores only accept orders to addresses in Japan, so to bring these home to Singapore you’ll need to ship to an overseas forwarding warehouse first and have a forwarder send them on — which is exactly where Buy&Ship’s Japan forwarding service comes in.
Three things to know before you order:
- 送料無料 (free shipping within Japan): all 6 product pages show 送料無料, but go by the latest product page.
- Combined forwarding: orders from different stores ship separately, and once they reach Buy&Ship’s Japan warehouse you can combine them into one forwarding shipment. Masks are small and light, so they are easy to ship together with other Japanese items.
- Fees and prohibited items: forwarding fees are charged by weight — check Buy&Ship’s prohibited and restricted items page and the latest Japan forwarding rates before you ship. If you are buying the wet mask, check it against that page too.

FAQ
Q1. Do I need to stock up on masks for the autumn and winter season?
If you already wear masks regularly, buy according to what you actually use — there is no need to stockpile. All 6 picks here are everyday masks, not medical masks; for whether extra protection is needed, please refer to announcements from Singapore’s Ministry of Health.
Q2. How do I choose the size of Japanese masks?
Japanese masks usually come in ふつう (regular), 小さめ (smaller) and こども用 (kids). Sizes vary by brand: for example, the Kowa Sanjigen listing gives 90mm × 175mm, and the Bihou kids’ mask is 80 × 132mm (primary-school size). If you have a smaller face, consider a 小さめ size; for kids’ masks, check the age range and cm size.
Q3. What are “JIS T 9001” and the “規格適合番号”?
JIS T 9001 is a Japanese performance standard for masks. Products that meet it show “JIS T 9001” and a 規格適合番号 (conformity number) on the package or product page. For example, the Iris Ohyama Nano Air Mask 50-mask listing states JIS T 9001 (general-use masks) and conformity number G42107004. Not every mask carries this label, and we did not check the other picks one by one, so go by the product page and packaging.
Q4. A pick is under ¥5,000 — how do I use the ¥500 coupon?
The coupon requires a single order of ¥5,000 or more, so put items from the same store in the same cart and check out together. Using the prices when we checked:
- Iris Ohyama Nano Air Mask: 3 boxes of 60 come to ¥5,040, or 4 boxes of 50 to ¥5,520
- Kowa Sanjigen: 2 packs come to ¥6,900
- Bihou kids’ mask: 3 packs come to ¥6,600
- Nodonuru wet mask: ¥4,305 each — add another item from the same store to reach ¥5,000
Each coupon can be used on one order only, and each Rakuten member can use up to 4.
Q5. How do I get the “Rakuten S$3 Special Shipping Discount Coupon”?
Spend on Rakuten Japan between 1 and 31 October and successfully use a total of 4 Rakuten Ichiba shopping coupons. The coupon will be credited automatically to your Buy&Ship account within the first 10 working days of the month after your Rakuten order is completed. Quota is limited, first come, first served — see the Terms and Conditions for details.
Q6. Which address should I use at checkout?
Use Buy&Ship’s Japan warehouse address and add your member number to the name field, so your parcel can be matched to your account once it arrives. After the seller ships, remember to declare the parcel in the app.
Q7. Can I buy from several stores and forward everything together?
Yes. Orders from different stores ship separately; once they have all reached Buy&Ship’s Japan warehouse, you can combine them into one forwarding shipment to Singapore. Every Rakuten order of ¥5,000 or more can use one ¥500 coupon, up to 4 uses per Rakuten member, so ordering from different stores makes it easier to use all your coupons.
Q8. What do “売り切れ” and “残りわずか” on a product page mean?
売り切れ means that color or size is sold out; 残りわずか means only a few are left, so order soon if you like it; 予約 is a pre-order, where you pay now and the store ships on the date shown. All the picks here were in stock when we checked, but stock changes at any time, so go by the latest product page.
