How about a Japanese tea set that he can use during his tea ceremonies at home? You can also include some premium Japanese tea leaves and a book on the art of Japanese tea ceremony as an added bonus. Another idea would be to find a local Japanese tea house and treat him to an authentic tea ceremony experience. If he already has a tea set, you could also consider a beautiful tea ceremony robe or a new tea bowl to add to his collection.
Or you can get him a star map with the date when he was born.
