Rare Amakusa Stone – Natural Japanese Sharpening Stone / Viewing Stone – Unique Layered Pattern – 0.85 kg – Japan

This is an authentic natural Amakusa stone (天草石 / Amakusa-ishi) sourced from Amakusa, Kumamoto Prefecture, Japan — a region internationally renowned for producing some of Japan’s finest natural sharpening stones and decorative viewing stones.

This particular piece is especially attractive due to its striking natural layered mineral formations, displaying beautiful concentric reddish and cream-colored sedimentary patterns formed over millions of years. The organic, asymmetrical shape and untouched edges emphasize its natural origin and aesthetic appeal.

Amakusa stones have been traditionally used for:

Finishing and polishing Japanese knives and tools

Sword polishing preparation (foundation work)

Calligraphy tools and craft finishing

And increasingly, as Japanese viewing stones (Suiseki) appreciated for their natural artistic beauty

Collectors, chefs, bladesmiths, and enthusiasts of Japanese craftsmanship highly value authentic Amakusa stones due to their historical importance and limited availability today.

This is an original natural stone from Japan — not a modern reproduction.

A rare opportunity to acquire a genuine piece of traditional Japanese stone heritage.
