Inkopolis is a major city and a presumed city-state and the main setting of the Splatoon series. It is the primary home of the Inkling race. It can be accessed through a manhole located in the basement of Peach's Castle. In addition to Meggy, it is also Axol's hometown.

Mario ends up here while chasing Meggy in SMG4: If Mario Was In... Splatoon and serves as the main setting of that blooper as well as If Mario Was In... Splatoon 2 and the film SMG4 Movie: Meggy's Destiny.


Inkopolis residents, including Meggy, absolutely despise anime. At some point Axol was born in Inkopolis and began to have a talent for anime, but was driven away due to the town's hatred of it. The hatred of anime is further explained because it is a sign of discrimination towards humans, which most of anime is based on.

In 2017, Mario accidentally arrives and meets Meggy and finally joins her team to make her win the competition but loses against The Ink Brigade.

In 2018, Mario and Meggy trained again for the next competition but engaged a fight with Desti who wanted to recruit Mario (but failed because she kept getting Mario's name wrong).

In 2019, it served as the training grounds for Mario, Luigi and Tari in SMG4: Meggy's Bootcamp, where Meggy gave them intense training for the upcoming Splatfest. Their victory is cut short when Desti stole their weapons, and had to get it back in the next episode.

A week later, during the Splatfest Incident, Inklings started to disappear around the city due to the anime characters created by Francis who abducted them. As a result, the whole city was placed under wide lockdown to prevent further incidents.

After the event of the island, all inklings were saved by Shaggy.

In 2020, due to Meggy being a human and no longer an Inkling, Meggy has no choice but to leave her hometown to stay in the Mushroom Kingdom after the final Splatfest.

The Inkopolis Tower, the landmark of the plaza.

The heart of Inkopolis, and also the hub of the first game. Many shops are set up in the area, including the Squid Sisters' studio. It also includes the large Inkopolis Tower, where Inklings head inside into the Battle Lobby to play in Turf War matches. The Inkopolis Plaza subway station is just south of the main plaza, and Meggy's Apartment is located further south.


Citizens of Inkopolis can get around the city at ease with two types of rapid transit systems. The first, a commuter train system connecting the suburbs and the Deepsea Metro, connecting the major areas of the city with 10 lines. Inkopolis Plaza subway station is an interchange with these two lines.

Notable residents



  • Though Inkopolis is Meggy’s home, it does not appear often in the SMG4 series. Its most notable appearance was in Meggy's debut episode.
  • In Splatoon, Inkopolis takes place in a post-apocalyptic world 10,000 years into the future. In SMG4's universe, it takes place in the present and is located close to the Mushroom Kingdom.
  • Inkopolis can be accessed via a pipe inside of Peach's Castle.
    • However, in recent years the city is starting to become more accessible, such as in SMG4: The Mario Showdown, where the cast was able to get there via Axol's drawings of Pokémon, and recently, hailing a yellow taxi to get there in SMG4: Super Mario Taxi, showing some evidence that there is a probably a link from the Mushroom Kingdom and Inkopolis physically on the surface. However, it is unknown if Mario had to cross a certain border to get there, hinting some evidence that Inkopolis is a seperate country from the Mushroom Kingdom.
    • As mentioned by Meggy in SMG4: A Day In The Life Of Everyone, Inkopolis has its own police force, called the Inkopolis Police, and have their own jurisdiction of the city rather than the Royal Mushroom Kingdom Police.
  • The Inkopolis that is shown in recent videos like SMG4: If Mario Was In... Splatoon 2 and SMG4: The Inkling Disappearances takes place in The Inkopolis Plaza rather than Inkopolis Square which is the current map in Splatoon 2.
  • It is referred to as "Splatoon land" in SMG4: Mario's Magical TV.
  • Unlike its neighbor, the multiracial Mushroom Kingdom, Inkopolis is seen as a homogenous nation, with Inklings comprising around 95% of the population.
