How about gifting him the complete Haruki Murakami Box Set? It includes all of his novels, short stories, and essays. Alternatively, you could pick his favorite Murakami novel and get him a first edition or a signed copy. You could also consider booking a trip to Japan, where Murakami is from, and explore the places mentioned in his books together. Another idea is to create a custom art piece featuring your boyfriend's favorite quote from a Murakami book.
Or you can get him a star map with the date of your anniversary.
