The fish market is a wonderful experience, even if you're not one of the few people tough enough to brave the 4AM lineup for the tuna auction. We went midday on a Saturday, and though there were quite a few people, it was not overwhelming and we were able to move with relative ease through the crowds to the different stalls. This place is a seafood lover's paradise with all kinds of familiar and less familiar sea species on display (to eat on the spot, or to take home). We tried one of the giant oysters for 500 yen and it was the size of a small chicken breast (no exaggeration), and quite heavenly. There are also plenty of small restaurant stalls. We did not do our research prior to visiting, but there are certainly some restaurants that are better than others. While wandering down an unassuming alley way (that was barely noticeable from the main pathway), we found half a dozen more restaurants, slightly more upscale, hidden away from the crowds. It would be worth it to do some research into the restaurants ahead of time to maximize your visit. A few reviewers mentioned the need to wear waterproof shoes. We did not know about this prior to visiting, but the floor was not wet when we were there and we did not get fish juice all over our shoes. You should be okay if you're careful where you walk.
It an okay market, but the big event I definitely the fish action and you have to get up at 3 am (03:00) in the morning to be able to see it. I would definitely recommend the market if you love fish and want to taste the freshness of what the Japanese sea has to offer. But be warned it is a bit pricey.
Going into the wholesale market after 10am is definitely recommended. Be careful where you're stepping and be aware of your surroundings as they're still working and the vehicles are moving around trying to move the fish. We were fortunate to see one stall prepping a large tuna and the skill it takes to properly divide all the cuts of meat! No pictures allowed in there. The outer market was fun to walk around too and choose a restaurant or two to try. I don't think any restaurant is really worth over 1 hour wait as the quality of fish there is fresh for everyone. If you don't want to wait, try buying some prepared sashimi inside the mall and eat it on the third floor!
Nothing like it, best of fish market I have been. Great selections of food was extra ordinary, with great and really fresh taste. I always going to fish market in Sydney every week and still really surprised by the creation that they can make from seafood. Even the display are pretty traditional that you can feel a great vibe when you go in there. Quite hard to see the tuna auction but if you just go for the food the tuna sashimi stall is the best!
Really cool market style atmosphere (think farmers market from America ). Prices for fish will be upwards of 1000 yen for a set of sushi. The one we went to had a option of 5 types of tuna for about 1500 yen. It was very fresh and very tasty. Be prepared for tightly packed alleyways and I recommend going after 10-11am as it will be a little less busy but still plenty of fresh wares available.
