Nanagou

"The Nanagou aren't landmarks for the sake of tuning. Enyou sent them as a lynchpin for fusing the two dimensions. A symbol of his resentment!!"

- Enjin Hiizumi describing the Nanagou, Chapter 19

The Nanagou (七郷, Na nagou) are seven giant pillar-like trees found in Sakurashinmachi originating from the Other World. They are the coffins of the seven members of the Hiizumi Branch Family which were tuned by Oushyuu Hiizumi. When the Nanagou bloom it will result in the assimilation of the two worlds.

Each nanagou is has a large shimenawa tied around it with large shide hanging from the rope and each being marked with a number one through seven.

An artificial nangou known as the Zero-gou was developed by the Senate.
