Vintage Japanese Bone and Bamboo Mah Jong set

Hi, trying to find out about this item my aunt left me when she passed.
She told me that she acquired it in Japan in the late 50s and it is
bone and bamboo, the instructions are japanese. Hoping someone can point me toward someone who can read Japanese writing and translate
the paperwork and give me more info about the game. It is not plastic or bakelite.

thanks any help would be greatly appreciated
