Had a good experience at Kaikeonsen, Tottori, with some water – sake boiled oysters. Had multiple different types of oyster to try, all you can eat (not sure if it was 60 or 80 min, for 3000 yen). Also had a good all-you-can-drink option, and you could bring in your own food as sides.
The store was 牡蠣乃家, the old man running the place was asking about how I found the place, so I thought I'd give it a shout out.
