I suggest getting him a gift related to his favorite anime. Here are some ideas:
1. A collector's edition DVD box set of his favorite anime series with bonus content and exclusive packaging.
2. A handmade replica of a prop or weapon from his favorite anime made by a skilled artist.
3. A framed poster or art print of his favorite anime character or scene.
4. A Japanese-style bento box filled with delicious snacks and candies from his favorite anime series.
5. A Japanese language course or phrases book, so he can learn and understand more about Japanese anime culture.
Or you can get him a star map with the date of your anniversary.
