01 / Utasai Beech Forest
Utasai Beech Forest has survivedtwo threats of logging.
The town writes that the beech forest running on from Honshu breaks off at the Kuromatsunai Lowland, which links Suttsu and Oshamambe, and names Utasai Beech Forest as its representative. Around 1944 a logging plan was halted by a scholar's appeal; in 1954 a petition from local residents kept the designation from being lifted.
