I enjoyed crab today here. It is fresh and sweet, reasonably priced. Highly recommended. There is also a farmer's market here and an aquarium (free admission) at the same location. A nice visit
It may not be as big as some other market and not as much choice but there are most of the things you’d want at a fish market to keep it interesting.
Gave it a high score as the seafood don are spectacular value for money at 1000 yen each.
Can taste how fresh it was and really worth the money.
