Vernal Equinox Day Vernal equinox (around March 20th to April 3rd) is one of the twenty-four solar terms
The days and nights are almost the same length, and from this day until the summer solstice, the length of the day gradually increases.

Also, on this day, the sun rises from the "due east"

It sinks in the "due west" and it is also the time of the spring equinox.

Ark Tategamori will reopen on April 12th.
Part of the facility has been handed over from the construction company, and preparations for opening are proceeding at a rapid pace.

We would appreciate it if you could come to the grand renewal opening of ArK Tategamori.
