How about a pair of taiko drumsticks? You could find a quality pair and even have them personalized with his name or initials. Another idea could be to surprise him with lessons or a workshop with a local taiko drumming group. If he likes to read, you could also get him a book about the history and techniques of taiko drumming. Finally, you could plan a special date night to see a taiko drumming performance together or even organize a private performance just for him.
Or you can get him a star map with the date of your anniversary.
