"Japanese food" was registered as a UNESCO Intangible Cultural Property in 2013. It is attracting worldwide attention as a healthy and fashionable food culture because of its characteristics that value the season and bring out the taste of the food itself. "Soy sauce" supports such Japanese food. Not only as a seasoning, but also as an entity that produces "umami" and "scent", it is also a great success in Edo food culture such as sushi and staining (maguro), tsukudani, soba noodles, oden, eel kamayaki sauce.
Soy sauce has been manufactured mainly in the upper part since ancient times, but "down soy sauce" will be supplied by sea to Edo, where the population has rapidly increased due to the opening of Ieyasu Tokugawa. Furthermore, since the middle of the 17th century, soy sauce production has become popular in the Kanto region in Choshi, Noda, Sahara, etc., and it has been possible to directly transport to Edo, a large consumption area, using the water transportation of the Edogawa and Tone Rivers, and the quality has improved. As a result, the supply of these "ground goods" along with the high-quality "down goods" becomes active, and the consumption of soy sauce increases. The distribution facilities for transport goods to Edo existed on rivers such as the Okawa, Nihonbashi River, and Hakozaki River, along rivers along waterways and canals. Fresh fish are Nihonbashi, rice is Kuramae, sake is Shinkawa, vegetables are Kanda, etc. It seems that the riverbank may have been decided depending on the supplies, but soy sauce is around the Hakozaki River, including the Gyotoku River, which fry the salt of Gyotoku. It seems that it was often fried. 
The Inari moat is one step from the banks of Gyotoku. It was reclaimed in Meiji period and now it is Tokanbori Street, but there is a soy sauce hall here. We spoke with Mr. Yamanaka of the Japan Soy Sauce Association.
The Soy Sauce Kaikan has offices of soy sauce-related organizations such as the Japan Soy Sauce Association, the Japan Soy Sauce Technology Center, and the Soy Sauce Industry Central Fair Trade Council. Unfortunately, there is no open to the general public such as the Soy Sauce Museum. On the window display on the outside of the first floor, there are soy sauce produced by soy sauce companies nationwide, soy sauce taste recipe & episode contest winning works, and soy sauce contests that are no longer used, and soy sauce.

In addition, as a soy sauce food education project, the Japan Soy Sauce Association Soy Sauce Information Center conducts a “Soy sauce knowledge doctor's on-site class” for elementary schools, etc. You can see it on the link (https://www.youtube.com/watch?v=nj9JZIYpD_U).
At present, of course, ships loaded with soy sauce barrels do not go back to the Hakozaki River, but due to such a history, there are the headquarters of soy sauce companies (Higeta), Tokyo bases (Yamasa, Higashimaru, Kinenne, Morita (JFLA), etc.), and there are also sake and food wholesalers Kokubun, Tsuchiura, which has its headquarters in Chuo-ku, and Kokubun, respectively.
