A Visit to the Omori Kaizuka

Ōmori Kaizuka 

(Omori Shell Mound)

The other day I wrote about Ōmori and I mentioned that there was a paleolithic trash dump there that was the first archaeological dig in Japan. I had a little free time so I decided to check it out and take some pictures for the site. Actually, it was a lot less interesting than I thought it would be, but I don’t want the pictures to go to waste. Hopefully, there’s some interesting stuff in here for you.

Near Omori Station there is a monument commemorating the 100 year anniversary of the discovery and excavation of the shell mound.

Today, the site of the shell mound is a quiet park.

After passing through the gate you walk up a hill (it was a “mound” after all).

For some reason there was an English sign. This is the only English at the site.

The structure in the background seems to be a reinforcement of the side of the shell mound. If you walk around it, you can actually go up to the top and get a feel for how tall the mound actually is. I’ll explain the water in the middle later.

Morse first noticed the mound when he passed by it on his way to Yokohama. Today the Keihin-Tohoku Line tracks are right next to the mound – the train line name means “Tokyo-Yokohama.”

Then a train passed by.

Omori means “Great Forest” and the area is still wooded today.

The reinforcing wall serves as a rest area. There are chairs and the walls are decorated with shells.
Every so often mist comes up from the ground in the center of the chill out area.
Very interesting!
Across from Omori Station I stumbled across a shrine called Sanno Hie Shrine. Check out my article on Tameike-Sanno for a little background on another shrine with the same name. This gave me a great idea for an article.

There were two smaller shrines to the left of the main hall.
And there they are.

  1. There IS an interesting story related to the site. When Morse discovered it containing ceramics and human bones, he concluded that this were the remains of paleolithic Ainu who had been – obviously to him – canibals. This was a big scandal throughout Japan: CANIBALS IN TOKYO! This irritating hypothesis was then refuted by the German adventurer and collector of Japanese art Henry von Siebold, second and younger son of the famous physician Philipp Franz von Siebold who was based on Dejima in the 1820s,had explored the country and had become the first foreign advisor to the newly founded ministry of foreign affairs in 1861. Anyway, Henry could prove that Morse was wrong, because the Ainu didn’t know ceramics arts and there were no traces of cannibalism in the Ainu culture. This was a great relief to Japanese intellectuals like Yukichi Fukuzawa, the founder of Waseda university.

  2. Thanks for the comment and that is an interesting story. I didn’t know about the cannibal thing. That’s crazy. lol

    BTW – I think you mean Keio University, not Waseda.
