Japanese Customs (as with most other countries) would not allow visitors to bring live plants (The Venus Flytrap), fruits or soil into their country.
When the scientist approaches the venus flytrap and sees a snake next to it the snake is clearly fake or dead as it is laying upside down with its mouth open, the scientist still pretends it is alive and attacks it with a shovel.
While in the mountains of Japan, a coyote is heard howling. Coyotes are only found in the Americas.
