Tsubokusa Soap

The Secret of Timeless Beauty from Japan

In the Edo period, beauty rituals were deeply connected to nature. Among the many healing herbs treasured for both mind and body, Tsubokusa — also known as Gotu Kola — stood out as a symbol of rejuvenation. Today, this legendary herb is reborn in a luxurious soap crafted with care in Japan, uniting ancient herbal wisdom with modern skincare science.


A Rare and Precious Ingredient

Across Asia and Europe, Tsubokusa has long been prized as the “Herb of Longevity.”

In the West, it’s celebrated for its remarkable skin-rejuvenating benefits, and in Japan, it quietly serves as the secret ingredient in many high-end cosmetics — often listed as Asiaticoside, Madecassic Acid, or Centella Asiatica Extract.

Because of its rarity and cost, it’s usually found only in trace amounts — but Modama Kobo, the producer of this soap, has infused it generously, drawing on their close relationship with organic growers.


The Power of Natural Cleansing

This artisanal soap is rich in natural Tsubokusa extract grown organically on Ishigaki Island in Okinawa, where pure water and sunlight nurture every leaf.

It gently removes impurities while nourishing the skin with active botanical compounds that help:

Restore elasticity and moisture
Calm irritation and sensitivity
Promote a smooth, youthful glow

Every wash feels like a soothing herbal treatment – a moment of calm reminiscent of an onsen retreat.


A Moment of Renewal

Unlike ordinary soaps, Tsubokusa Soap leaves your skin soft, hydrated, and radiant, without any tightness. Its delicate herbal aroma brings a sense of peace to your daily skincare ritual, allowing you to rediscover the Edo-era wisdom that beauty begins with balance.
