The Western side of Yowa Valley. An area inhabited by Western-style Yokai. Futsuka's Western-style house is located deep within this side. Vampires, Werewolves, Gargoyles, and other overseas/Western Yokai gather here. The Yokai on the Western side are bellicose and will often challenge humans to a fight upon sight. Western Yokai occasionally visit Futsuka's house to hang out.

The Japanese side of Yowa Valley. An area inhabited by Japanese-style Yokai. Karashu's Japanese-style house is located deep within this side. Oni, Tengu, Zashiki-warashi, Bake-gitsune, and other Japanese Yokai gather here. The Yokai on the Japanese side are quiet and will not fight unless attacked. However, each Yokai possesses high strength and stamina, making them formidable foes. At night, they become aggressive like those on the Western side. Japanese Yokai occasionally visit Karashu's house to hang out.

E-machi: A town slightly larger than Kaze Village, with a streetscape resembling Japan's Edo period. The people living here wear kimonos and are very friendly to Ukiyobito. Kaze Village: An area that looks like a normal village, slightly smaller than E-machi. Many people are engaged in some form of industry. Technology is slightly more advanced than in E-machi, with electricity and electronic devices available. However, there are no electronics for entertainment; they are strictly for daily necessities. The population is smaller than E-machi, and while there is interaction, it is not very frequent.

The most unusual lake in Seriki, located in Yowa Valley. Whether you are a human or a Yokai, if you are a Ukiyobito, it is not recommended to approach it.

The boundary between the Western and Japanese sides in Yowa Valley. One of Seriki's most otherworldly and fleeting places where the four seasons are felt most intensely. Both Western and Japanese Yokai are present here. The Yokai living on the Kyoshun Line are more intelligent than average Yokai. These intelligent Yokai have settled here, finding entertainment in watching the changing seasons. Because they are smart and dangerous, it is better to talk your way out and flee before a fight breaks out.

A vast sea on the opposite side of the Hitokaze House, across the Yowa Valley. Only water-related Yokai live here. Any Yokai related to water, whether Western or Japanese, can reside here. For example, Western types include Mermaids and Kelpies, while Japanese types include Hashihime, Kappa, and Mizuchi. It is safe if you are with the two Creators or if Guest is a Yokai, but a lone human risks being dragged into the sea by the Yokai. A unique culture developed by water Yokai exists beneath the waves.
