Mount Nantai

From Inkipedia, the Splatoon wiki

Mount Nantai is a location mentioned in Splatoon 2 and Splatoon 3. It is never visited by the player, only being seen on the map of Inkadia and the Splatlands from Splatoon 3.


Mount Nantai is a mountain in Inkadia.

In the Octo Expansion, when Cap'n Cuttlefish is first contacted by Off the Hook, they mention they are calling from Mount Nantai, which Cap'n Cuttlefish mentions is near Octo Valley. It is implied that Pearl goes to Mount Nantai to practice her shockwave-causing singing voice (seen in Sunken Scroll 1 in Splatoon 2) away from civilization, implying the mountain to be mostly free of people.[1]

In Marina's chat room, Mount Nantai is mentioned as the location where Pearl and Marina first met. Marina describes herself having visited Mount Nantai every day for a week after escaping Octarian society, in the hopes of meeting Pearl again. This led to the formation of Off the Hook.

Ryu Chang, the drummer of SashiMori, is stated to come from the base of Mount Nantai, in an area with a mountain stream.

According to HaikaraWalker, there is a Mount Nantai astronomical observatory, and there are night sky viewing parties on a regular basis, sponsored by Grizzco Industries.[2]



  • Mount Nantai stands at around 2,657 feet tall, or approximately 810 meters. This number in meters may be a reference to how octopuses have 8 legs, and squids have 10.
    • There is a real Mount Nantai in Japan, which is 8,156 feet tall, or approximately 2,486 meters, three times taller than the Mount Nantai in the Splatoon series. Despite the similarities in name, It is unclear if it is intended to be the same mountain.
  • At Tentakeel Outpost, when Callie mentions she is afraid of ghosts, Marie retells the "mystery of Mount Nantai": "a tiny, pale shadow wriggles and writhes deep within the forests of Mount Nantai. And if you listen closely on a quiet night... you can hear an ear-splitting scream loud enough to shatter glass!" It is implied that this creature is simply Pearl, as she is short and used to practice her extremely loud voice on Mount Nantai.
  • In the manga, Mount Nantai is the home of Ammoses Shellendorf's treasure, where it is protected by three guardians: Fierce Fishskull, Jetflame Crest, and Justice.
    • Additionally, Chapter 25 of the manga shows the specific location of Mount Nantai in relation to Octo Valley; the mountain is close to the octopus rock formation found there, though the two are separated by water.


Mount Nantai likely comes from 軟体 nantai, the Japanese word for mollusk. Its name is homophonous with the real-life Mount Nantai in Japan, a sacred mountain popular with hikers that often hosts spiritual gatherings.
