One of my favorite places to visit is the Tsukiji fish market. Be sure to go there early in the morning and see the bustling wholesale market in action. You can even go super early and watch the giant tuna sales if you’re lucky to be among the first waiting. Afterwards, explore the outer market and have sushi and beer for breakfast – delicious! The historic market will be moving from this location in the near future, so it’s worth seeing while it still exists.
