One idea could be to purchase a sushi-making kit that includes all the necessary tools to make sushi at home. You could also consider getting him a set of high-quality chopsticks or a Japanese style sushi knife. Another option could be to take him on a sushi-making class or a Japanese cooking class so that he can learn more about how to make sushi and enjoy it even more. You could also plan a special sushi dinner at a high-quality Japanese restaurant as a Father's Day treat.
Or you can get him a star map with the date when he welcomed you in this world.
