We walked from the Tougendai station to the Hakuryu (white dragon)-shrine, through the Kuzuryu (nine headed dragon)-shrine in Hakone. During the way, we saw a small insect attacking an earthworm. I was surprised and took a video. This insect is Shizuoka-samushi in Japanese. Its scientific name is Carabus esakii Csiki. This insect is pretty fierce. It cut the earthworm and run away. The earthworm was still alive and hid soon though.
