Tokyo Mate
Koisuru Oshiri, known as Japan's "butt soap," organized for 2026. Before buying at Don Quijote or a drugstore, check the price, lineup, how to use it, and the cautions all in one place.
Koisuru Oshiri: Japan’s Best-Known Hip-Care Soap
Pelican Soap (ペリカン石鹸) is a soap specialist brand founded in 1948 that has kept its place in Japan's body-care market for more than 70 years. Among its products, the "Koisuru Oshiri" introduced here has, since its 2016 launch, passed 10 million in cumulative series sales as of 2024, and even took first place in the body-care category at the @cosme Best Cosme Award 2022, Japan's largest beauty platform. It is a local staple.

🌱 Key ingredients and feel
Koisuru Oshiri contains two kinds of scrub particles: peach-seed powder and konjac-derived grains. It is a soap that gently cleanses body areas where dead skin builds up easily, such as the hips, of course, but also the thighs, back, elbows, and knees.
On top of that, it adds six moisturizing essences including peach leaf, kiwi, and aloe vera, and emphasizes a finish that does not leave skin feeling tight after washing. That said, since it is a product with scrub particles, if you have sensitive skin, it is best to test it briefly on a small area first.
📌 At Don Quijote stores, another hip-care soap called MOMOURURI (桃潤) is also sold. The product introduced in this post is not MOMOURURI but Pelican Soap's (ペリカン石鹸) Koisuru Oshiri (恋するおしり) series, so be sure to check the package when buying in store.
Koisuru Oshiri Series: The Full Lineup
Starting from a single original soap, Koisuru Oshiri has now expanded to a four-product lineup of soap, lotion, scrub, and body butter, plus two limited editions. Choose one to match your situation and skin concern.
1. Hip Care Soap (the original)
The pink heart soap that started the series after its 2016 launch. A good entry product for daily care, gently managing dead skin while you shower every day.
- Recommended for: beginners, daily care
- Size: 80g (solid soap)
- Japan official price: ¥715 (tax included)
2. Hinyari Cool (summer limited edition)
It contains menthol, so it has a cool, refreshing feel while you wash. It has 3.5 times more scrub particles than the original, making it a limited edition you can use for a fresher feel in sweaty seasons. The package is a cool blue, so it is easy to spot at a glance in store.
- Recommended for: summer season, strong scrub care
- Size: 80g (solid soap)
- Japan official price: ¥715 (tax included)
3. Ishiken Scrub (foam scrub)
The newest in the series, released in April 2025. Using Pelican's own technology, the soap is finely broken down into a scrub form. Add water and massage, and it gently foams up for 3-in-1 care: scrub, cleansing, and moisturizing.
- Recommended for: special home care once or twice a week
- Size: 180g
- Japan official price: ¥1,980 (tax included)
4. Hip Care Body Lotion (moisturizing finish)
A dedicated body lotion you apply as a finish after smoothing dead skin with the soap. Its biggest feature is that it is not sticky, so you can put on underwear right after applying it without any discomfort. The sweet peach scent, blended in Grasse in the south of France, even sets the mood after a bath.
- Recommended for: dry skin, keratosis pilaris ("chicken skin") care
- Size: 200ml
- Japan official price: ¥990 (tax included)
5. Hip Care Body Butter (ultra-moisturizing cream)
The newest product, the most focused on moisturizing care in the series. It contains three plant butters such as shea butter, plus retinol and niacinamide, so it can care for even very dry skin. Squeeze the tube and the cream comes out in a cute heart (hip) shape, adding to the fun of using it.
- Recommended for: very dry skin, intensive nourishing care for chicken skin
- Size: 100g
- Japan official price: ¥1,320 (tax included)
🎀 Sanrio My Melody collaboration limited edition

Tax-Free + Coupon Tips at Don Quijote & Drugstores in Japan
Koisuru Oshiri is a hip-care product you can find relatively often at Don Quijote, major drugstores such as Matsumoto Kiyoshi, Welcia, Sugi Pharmacy, Sundrug, and Tsuruha, and at variety stores like Loft and Hands. Stock and prices can differ a little by store, though, so compare with the official price before buying.
1️⃣ Getting tax-free
Japan's consumables tax exemption applies when the amount you buy at the same store on the same day is ¥5,000 or more before tax. With just one or two bars of Koisuru Oshiri it is hard to clear that threshold, so the key is to pay for it on one receipt together with other cosmetics and daily goods.
2️⃣ Using drugstore coupons
Add the drugstore's own discount coupon on top of the tax-free benefit and you can get it for even less than the list price. Each store has a different issuing method and discount rate, so it matters to grab the coupon for the store you plan to visit in advance. You can check the latest coupon info and how to get it for each store in the posts below.

How to Use It Correctly + FAQ
Using Koisuru Oshiri is very simple.
Wet the soap well with water, hold it directly against the area where dead skin bothers you, and gently massage in circles (nade-arai / なで洗い), then rinse off with lukewarm water and you're done. Of course, you can also lather it with a foaming net or body towel like a regular soap.
🎯 Recommended areas to use
You can use it on the hips, of course, but also all over the body where dead skin or chicken skin is a concern, such as the backs of the thighs, the back, elbows, and knees. (※ Because it contains scrub grains, it is not recommended for washing the face.)
📅 Recommended frequency
There is no set number, but depending on your skin type, it is good to start at 2 to 3 times a week and gradually increase the frequency if there is no irritation.
Frequently asked questions (FAQ)
Q1. Are MOMOURURI soap and Koisuru Oshiri the same product?
No. The two are often treated as the same thing, but when you check in store, only the packages look similar, while the brand, size, and price are all different. They are separate products. Don Quijote often displays both together, so before buying, be sure to check for the "恋するおしり" or "Koisuru Oshiri / ペリカン石鹸" marking on the package.
Q2. What is the difference from the famous back-acne soap For Back?
They are products from the same maker, Pelican Soap, but their uses are completely different.
- Koisuru Oshiri: a regular cosmetic for dead-skin and moisture care
- For Back (ForBack): a medicated soap (quasi-drug) specialized for back and chest acne care
If your goal is dead-skin care for the hips and thighs, choose Koisuru Oshiri; if your goal is back-acne or acne care, choose For Back.
Q3. Is it safe for pregnant women or babies?
It is a regular cosmetic grade, so there is no major restriction in terms of ingredients. However, since it contains fine scrub particles, those with especially delicate baby skin or sensitive skin should do a patch test on a small area before use.
Q4. Can I buy it outside Japan?
You can get it through some import or proxy-buying services, but it tends to cost nearly double the local Japan price (¥715). If you have a trip to Japan planned, the best deal is to stock up on a couple of bars at Don Quijote or a drugstore. Add tax-free on top and the value gets even better.
If rough, bumpy body skin and chicken skin have been on your mind for the coming summer, why not pick up the Japanese butt soap Koisuru Oshiri introduced here? And right before you pay, don't forget to grab a drugstore coupon that adds an extra discount on top of tax-free.
