Nebukawa stone
This stone is associated with Tokugawa Ieyasu and was used in the construction of Edo Castle.
Tokugawa Ieyasu was a great ruler who achieved the unification of Japan until his later years.
During his childhood, he was held hostage by the Imagawa family and had a very hard time.
Like Akabosa stone, it is mined on the surface of Komatsu stone.
With its smooth and shiny surface, this famous stone from Kanagawa Prefecture has been so popular that it sparked a hege stone boom in ancient times.
Because of its plate-like structure, it is a type of "hege stone" whose surface peels off easily.
This stone was formed when the Hakone volcano erupted about 400,000 years ago and the lava that flowed into the sea cooled rapidly.
