Reviews Summary

Visitors find the Omori Shell Mounds to be historically significant, marking the dawn of Japanese archaeology. The sites offer a unique glimpse into prehistoric life, with monuments and gardens preserving this legacy. While not a major tourist attraction, it's a worthwhile stop for those interested in history.

"There are a lot of shells in Omori park and I’m guessing this is some kind of monument to this place’s shelly history"

Matt B

"A historic site I noticed when visiting the Omori Shell Mound Ruins Garden near our site.

After reading other people's comments, it seems that this is in Ota Ward and is registered as a historic site separately from the park in Shinagawa Ward.

Our site only has a monument and a signboard about Morse, but it's on NTT Date's premises and even the monument by the train tracks is well-maintained."

わしわし

"The Omori Shell Mound historical site is located in two locations, one in Shinagawa Ward and one in Ota Ward.
This is the one in Ota Ward. It's located along the train tracks, so many people will have seen the stone monument.

The reason there is a site in each ward is because Edward S. Morse did not specify where he discovered it, and it was later discovered that it was in Shinagawa Ward.

So basically..."
