Japan Standard

Japan's altitude was initially determined based on the survey value of water level station, Reigishi Island.

It's a little less noticeable, but it's near the observatory Symbol Tower.

 

 

For the first time, Story 2

There is an explanation from that time (the early Meiji period).

In elementary school excursions (outdoor classes), Japan's altitude is based on the Japanese standard point near National Diet Building.

I remember the teacher told me that the height of Mount Fuji is based on this point.

This is also the origin of Japan's benchmark.

 

For the first time, Story 2

At that time, it was regrettable that the surface survey of the water level station on Reigishi Island was based.

I don't think he did it. (I went to a school in Chuo-ku, Tokyo.)

 

 

For the first time, Story 2

In addition, there is a description on the Internet.

"The Japanese standard is regularly measured from the oil pot test tide field in Misaki, Miura City, Kanagawa Prefecture, to check the altitude value."

And it was not touched by "Reigan Island water level station".

Please know "the first time at altitude" by all means.
