Would this be a good gift?

Years ago I rented a room from a man for 6 weeks in Osaka, and in May I will again rent from him for 3.5 weeks for my honeymoon. He has given us an absurdly low 10,000 yen price tag for this.

Anyhow... I am trying to decide what to take him as a gift. Any suggestions? I had thought about local things, but there isn't much I can think of besides some fruit preserves or something like apple butter or sweet potato butter (I am from North Carolina).

I don't want to take him generic candy bars that you can find anywhere, with my luck I would choose something available in Japan. Does anyone know of good candies you can't find in Japan?

Sake had crossed my mind too, but I probably won't have time to go to a store for sake before we see him. Plus I am not much of a drinker and he would probably want to share it with us and I don't want to be rude by not sharing it with him.

Stop at the duty free shop at your international departure airport. They have scads of good candies, liquors, etc.

Buy him something nice. I would not recommend going cheap.
