Tokyo is known as one of the biggest cities in the world and people don’t expect to encounter wildlife there. It is true, and it would certainly be difficult to encounter wildlife in the heart of the city. However, Western Tokyo is full of nature, and Mt. Takao, which is only one hour by train away from the city center, is a place where one can encounter nature and many wild animals such as squirrels, badgers, and raccoons even though it is easily accessible from central Tokyo. The most popular wildlife there is the Japanese Giant Flying Squirrel. It is endemic to Japan. This species that has a cute appearance and unique gliding behavior is abundant in Mt. Takao. Mt. Takao is rich in biodiversity because of the special relationship between Japanese culture and the mountain. However, not many people are aware that Tokyo is home to a lot of wildlife. The purpose of this film is to make people aware of it, to let them know that they have wonderful nature and wildlife on their doorsteps, and to raise awareness of environmental issues as people living in a big city where many human activities which have a significant impact on the environment are happening.
