Shoubudani is mine super close to Nakayama and produced similar stones as Nakayama usually super fine and hard
Sometimes in Japan shoubudani stones have been sold as Nakayamas
Perfect for knives and tools
Very very easy stone to use ! Very fast for its hardness and quite fine !
No toxic inclusions or lines at all very very clean stone
Amazing bright colour
Best to use with Nagura ! But can be used without
