1,200 YEARS OF PRECISION
Woven in Kyoto by artisans with 1,200 years of textile mastery. KOSHI's dual-thread design lathers and exfoliates at once — the only scrubber engineered to do both.
Frequently Asked Questions
Isn't it too rough on skin?
No. The dual-thread weave is engineered to exfoliate without being harsh. One thread buffs dead skin away, the other generates lather to cushion the stroke. You get deep exfoliation without raw, irritated skin. Even sensitive skin types see results within a week.
Will it actually help with back acne and KP?
Yes. Back acne and keratosis pilaris both come from dead skin buildup and clogged pores. KOSHI's textured thread removes that buildup every shower. Most people see improvement in 2–3 weeks of regular use. The key is consistency.
How often should I use it?
Daily for best results. Unlike harsher scrubs, KOSHI is gentle enough for everyday use. Use it in your regular shower routine — one pass with body wash is all you need. Most customers use it daily without irritation.
How long does one KOSHI last?
12+ months with daily use. The rip-resistant weave is engineered to hold its texture longer than standard loofahs or washcloths. Most customers replace theirs once a year, but it'll last longer if you use it less frequently.
How do I wash and dry it?
Rinse it after every shower and hang it to air dry. The breathable mesh dries in a few hours — much faster than loofahs. No special washing needed. Once a week, toss it in the washing machine if you want extra clean. It won't fall apart.
Why is this different from other Japanese towels?
Most Japanese towels do one thing — exfoliate. KOSHI's dual-thread design lathers and exfoliates simultaneously. One thread builds lather from minimal soap. One buffs dead skin. You get a complete clean in one tool. That's the difference.
Can I use it on my face?
Not recommended. KOSHI is designed for body exfoliation — it's too textured for facial skin. Use it on your back, shoulders, legs, and anywhere else you need deep exfoliation. For face, stick with gentler exfoliants.
How do I reach my entire back?
That's the whole point. At 46 inches long, you can grip both ends and scrub your entire back without contortion or asking someone for help. One long stroke covers areas loofahs and gloves always miss.
