One idea could be to take him to a J-pop concert, if there is one scheduled in your area. Alternatively, you could create a J-pop themed night at home. You could order in his favorite Japanese cuisine, decorate the living room with Japanese lanterns, and play his favorite J-pop songs. Another idea could be to get him J-pop merchandise, such as CDs, DVDs, or posters, of his favorite artists. You could also consider getting him J-pop clothing or accessories, such as a t-shirt or hoodie with his favorite J-pop bands or anime characters. Gifting him an experience, such as a Japanese language class or a trip to Japan to attend a J-pop concert, could also be a great gift idea.
Or you can get him a star map with the date of your anniversary.
