The map focuses heavily on rooftop combat and clipping is very lenient. One of the mottos when making this map was "clip only if you have to," so areas like the far off islands, the roof tops, hiding spots are free game.
Suijin was the first map made with the Japan Content Pack.
The map was initially created as an Arena map. Later this King of the Hill version was created.
A portion of the money made from sales of Gun Mettle Campaign Pass for the Gun Mettle campaign goes to the authors of this map.
- Temple Tower: At the center of the map is a large tower that houses the control point inside. The tower is open on three ends on ground level, and has a second level that can only be accessed from the rooftops. Two Byōbus are aligned along the control point as cover from the doors.
- Calligraphy Temples: On the mountainside by the waterfalls are two team oriented temples. Both temples contain a medium Health and Ammo kit, as well as a small Health kit between them. Also between them is a bridge to the control point.
- Rooftops: All of the rooftops of the temples are accessible and can serve as a shortcut, or a tactical advantage. Access to the rooftops can be achieved by: climbing from the plank ramp near each team's calligraphy temple, from the cliffside temple's second floor, or by Rocket jumping/Sticky jumping.
- Cliffside Temple: At the edge of the cliff is a temple with two medium Health kits in it. There are three ways to the temple: From a bridge at the side of the Temple Tower over the cliff, or from the team's side jumping across some precarious rocks. The temple has a second floor that can be used as a shortcut to the Temple Tower.
- Far islands: Past the edge of the cliff are two small rock islands. Jumping classes can reach them, but Engineers can't build on them.

- A Killer's Kabuto, a Half-Zatoichi, and Conniver's Kunais can be found in the supply locker. Additionally, a banner of Concheror can be seen on the table in respawn room.
- Inside both teams' spawns are big signs that spell their team's color in Japanese; '赤', meaning red, and '青', meaning blue.
- If a player shoots or hits the gong in their spawn, it will make a loud sound (the unusued "Prayer Bowl" Noise Maker sounds from the Japan Charity Bundle). However, the gongs around the rest of the map do nothing when attacked.
- The two sounds heard at the beginning of a round and when the capture point becomes available are used by the Koto Noise Maker.
- According from map creator, the pagoda on this map was made as a shrine to the Gravel God.
