We had a very interesting tour with Mariko. She had the good idea to bring a book full of pictures of he fish market and she comment them while we wait for our turn to visit the market. It made the wait shorter. We could see he buyers do their estimation work before the tuna auction. After Mariko show us the shops and restaurants of the public area and the Nomi Yoke Shrin. She even make us taste the famous japanese omelette. She gave us the keys to understand how work this market. Many thanks to Mariko
