Hōrai (ほうらい Hōrai?) is the center region of Kotaku and is under the rule of Lord Tensen where they live, train, and conduct experiments. The Dōshi also reside in Hōrai as students and servants of Lord Tensen.


The palace is constructed as a massive fortress modeled after China's Epang Palace. Since it is constructed like a traditional palace, it is divided between a large inner castle and outer structures.

Within the inner castle are temples ( Miya?, Viz: Sanctums) based on the five training methods of immortality each Tensen specialize in. The palace's interior follow the principles of Feng Shui to have "harmony" with the surrounding environment. Ryumyaku is applied by constructing buildings and artifices atop of places with great outpours of Tao energy, while also applying Ryuketsu by designing their corridors, roads, etc. along the paths where they flow. However, since the Ryuketsu is liable to change, the palace is constantly renovated to maintain the harmony.

The outer section is surrounded by golden mystic statues and leads to a building that connects to the palace through a bridge.
