Nanasho Slippers

Founded in 1947 (Showa 22), Tokyo Sangyo runs an in-house factory in Kitasenju, Adachi-ku, Tokyo — consistently handling slipper production, finishing, and inspection. While also producing for domestic and overseas brands, the company continues developing and manufacturing its own "Nanasho Slippers" and original slippers. The thought of "letting as many people as possible know the goodness of Japan-made slippers and designing a comfortable life" forms the core of its craftsmanship. The base is at 17-13 Senju Asahicho, Adachi-ku, Tokyo 120-0026.

What's spoken about in Tokyo Sangyo's craftsmanship is not simplification for price, but ingenuity to "make wearing comfort better." A moderately firm insole board firmly supports body weight, and construction is adjusted so the opening doesn't lose shape over time. The toe curve has been refined dozens of times — approaching a feel that fits the foot and stays unfatigued even after long wear. The aim is a pair where you want to "wear them again next time" in daily life. Details make the difference in comfort underfoot.

On the Nanasho Slippers online shop, models such as "Winner," "Vision," and "Walker" are lined up. With elegant sheen jacquard fabric, designs with glitter woven into mélange bases, and other expressions to choose for your interior — the appeal is the variety. Some models use approximately 7mm-thick felt soles or soft eco-leather "quiet" soles — also considerate of footstep noise on flooring. Sizes vary by design — S, M, FM, ML, L, LL, and more.

For care, avoid washing with water. Gently brush stains or wipe with a cloth lightly dampened with water or diluted mild detergent, then dry in the shade. With dark colors, friction in a wet state may cause color loss or transfer — handle gently. Repairs include re-adhesion for sole separation — consultation is free (shipping costs apply). Shipping is a flat 660 yen nationwide (excluding Okinawa), free over 3,980 yen. Inquiries are also accepted by phone (+81-3-3882-4860) or email.

Kitasenju factory — all the way through final inspection

Nanasho Slippers are produced, finished, and inspected at the in-house factory in Kitasenju, Tokyo. At a site also handling production for domestic and overseas brands, the workshop layers careful material cutting and sewing — building slippers designed to be worn comfortably day after day. Through the factory-direct online shop, the same factory's models can be purchased as-is.

Construction ingenuity for "getting better"

To support body weight of dozens of kilograms, a moderately firm insole board is adopted. Construction is devised so the opening doesn't lose shape, and the toe curve has been refined again and again. Aiming for a feel that fits the foot and stays unfatigued even after long wear, the slippers are tuned in details. A design that lightly supports each day's steps.

Materials and soles tailored to daily life

The lineup includes models using jacquard fabric with a subtle sheen, and designs with glitter woven into a mélange base. Some models adopt approximately 7mm-thick felt soles, or soft eco-leather "quiet soles" that suppress footstep noise. You can choose touches gentle on flooring.

Sizing and care to use slippers long

Sizes vary by design — S, M, FM, ML, L, LL, and more. As a guide: S is 22.5-23.5cm, FM is unisex 24-25cm, L is 26-27cm. Not machine washable — gently brush or wipe stains. Re-adhesion of sole separation can be consulted as a free service.
