How about getting your friend a set of traditional Japanese tea ceremony tools such as a tea bowl, whisk, scoop, and tea caddy? You could also include a package of high-quality matcha tea for them to use during their tea ceremonies. Another idea is to get them a book on the history and art of the tea ceremony or a certificate for a private tea ceremony experience with a tea master. Additionally, you could find a local tea shop that offers classes or workshops on tea ceremony and gift your friend a spot in one of them.
Or you can get her/him a star map with an important date you share.
