How about a traditional Japanese tea set that he can use for his tea ceremonies? You could also consider getting him a book on the history of tea ceremonies or a guidebook on how to perform a tea ceremony. Perhaps you could also treat him to a tea tasting experience or a special tea ceremony workshop where he can learn more about tea and the art of the ceremony. Additionally, a subscription to a tea of the month club could give him the opportunity to explore new and unique teas.
Or you can get him a star map with an important date you share.
