It's a bit. (The time machine arrives at the old Tsukiji.)

Dr. "This is Tsukiji in the 1650s (Edo period)."
Bo, "Hey, Dr., it's completely different from now. That's the sea."
Doctor, "Yes. At that time, Tsukiji was near the mouth of the Sumida River."
"Hey, Dr. There are a lot of people doing landfill work there. Let's listen to everyone's conversation with a little high-performance microphone."

"This area is going to be rough today,"
Mr. Kuma, "Let's stop working today,"
Master "It's a precious land I received from the Shogunate, so let's do our best a little more."
Mr. Kuma, "I understand, my master. If you have land here, let's build a great temple."
"Of course. A monk in Asakusa was burned by a fire, and I got the Shogunate a land to build a new temple, but that's not in the sea.…」
Kuma-san "Oh, my master, something is floating in the sea!"
"Let's raise it. (white tears) Oh, what is it? It's the sacred object of worship of Inari Oga."
Mr. Kuma, "Oh, let's make a shrine hall that enshrines this sacred object of worship."

(Boya and Dr. who were watching this event gently.)

Bo, "Dr., we were able to witness a historical moment!"
"Yes, sir. In this way, Haji Shrine was built in Tsukiji. And this new land was named Tsukiji."
