Tadataka Ino Memorial Monument

From Hakodate mountain to Nemuro

Original Text

On the side of the observatory at the top of Mt. Hakodate, there was a monument with a famous bronze portrait of Tadataka Ino. It seems that he measured Ezo from Mt. Hakodate to Nemuro. His first goal was to "measure the size of the earth", but he is a great person.

A step that leads to the "Japan Zone"

Original Text

Immediately after getting off the Hakodate Mountain Ropeway Mountaintop Station, there is a relief on the wall of the observatory to commemorate Mt. Hakodate as the first starting point for surveying Hokkaido. Tadataka Ino studied astronomy and calendar studies from the age of 50, and when he was 56 years old, the shogunate recognized the accuracy of the map that surveyed Hokkaido from Mt. Hakodate, and eventually led to the achievement of completion of the "Japan complete map". It's a small relief, but it's deeply moved.

Measurement の starting point

Original Text

He started here to survey Hokkaido. It is just off the cable station on Mt. Hakodate. Maybe you don't have to go all the way.

You climbed this far.

Original Text

It is a monument set up to commemorate Tadataka Ino's visit to Mt. Hakodate when he measured Ezo. I am surprised to think that he has climbed so far in the Edo period.
