The season of the cicadas has come to Kotori no Mori. The songs of the
cicadas were so heavy. I think the name of the forest must be changed to
"Forest for Cicadas", in this season.

A wisteria trellis near the entrance of the forest were rebuilt.

According to a male ranger, since decontamination work in the forest has
finished, the numbers of visitors has been increased: roughly speaking,
the numbers of visitors in recent months were about 70 % compared to that
before the quake. In fact, although I did not meet a visitor in the forest,
I saw a woman who finished walking in the forest, at the road from parking
area to the nature center.

Acording to the ranger, no remarkable change of the ecosystem of the forest
was observed. Only major change of the forest he found was that he can
hear few children voices in the forest.

The monitoring post showed that the radiation level at the parking area
was 0.154μSv/h. Acording to the ranger, the radiation level in the forest
was 0.2-0.4μSv/h at the area where decontamination was finished, and
almost 0.6μSv/h at the area where decontamination has not done.
