*[Entry to Taroshi Falls will be closed from February 14th] Taroshi Falls , located in Osegawa , Ishidoriya Town, where a measurement event was held on February 11th, will be closed to the public from Saturday, February 14th, as rising temperatures have caused the icicles to melt, increasing the risk of them collapsing.

The water from the Togeshi Forest that flows into the Kuzumaru River freezes on the mountainside, forming large icicles. The thickness of these icicles is measured and used to predict the harvest of the year.
"Taroshi" means icicle, and is a corrupted version of "taruhi" (hanging ice). It is said that the name "Taroshi Falls" came from the fact that the icicles that form resemble a waterfall. The waterfall is about 13m high.
A measurement is held every year on February 11th to measure the thickness of the tree. The largest thickness ever recorded was 8m, set in 1978, when there was a bumper harvest.

*The measurement will be carried out regardless of whether there are icicles or not. The measurement result for 2026 was 5.2m .
