How about a travel book that highlights different cultures around the world? Another idea could be to enroll him in a cultural exchange program or language immersion program to further his interest and understanding of different cultures. You could also consider gifting him a language learning software or a book to help him learn a new language. Alternatively, you could create a shadow box with mementos from your past travels or from cultural exchange programs you may have experienced together. This could include a map, postcards, tickets, and photos to serve as a reminder of your time spent exploring other cultures.
Or you can get him a star map with an important date you share.
