I suggest getting your husband a Pachinko machine! It's a unique and personal gift that he'll enjoy.
Alternatively, you could get him a book about the history and culture of Pachinko, such as "Pachinko: A Cultural History," by Isaac Cronin. Additionally, you could also get him some Pachinko balls or accessories to enhance his gaming experience.
Or you can get him a star map with an important date you share.
