Monster slides and banana benches: these are Tokyo’s most surreal children’s parks

Tucked inside a quiet residential pocket just north of Kagurazaka Station, Akagi Children’s Park feels almost too strange. Its main attraction is a huge concrete elephant slide built into the park’s natural slope, with two elephants forming a sculptural little playground kingdom. It’s totally old-school Tokyo magic: grey, slightly surreal, and somehow emotional in the way forgotten neighbourhood things can be.

The park itself is small, with a sandpit, animal play equipment and toilets, so this is more of a quick stop than a whole mission. But as a photo spot, it’s excellent. The elephant has that slightly haunted, beautifully aged quality that makes it feel like a public artwork disguised as playground equipment. Go for a Kagurazaka wander, a coffee, then this very important elephant appointment.

Every neighbourhood deserves a resident robot. Oji 6-chome Children’s Playground, also known locally as Robot Park, is watched over by a big blue retro robot whose arms double as playground equipment. One arm works as the stairs, the other as the slide, and the head becomes a cockpit-like platform where small children can live out their pilot fantasy. Gundam, anyone?

Besides the bot there’s more standard playground pieces too, including swings, a sandpit and bars, but the robot is obviously the main character. It has the chunky, slightly handmade look of a children’s TV prop from another era – not slick, and absolutely better for it. It’s good for kids, obviously, but also for anyone who enjoys Tokyo’s quieter residential oddities: the kind of thing you would never find unless someone told you it existed.

Banana Park is exactly what it sounds like and somehow still funnier in person. Hidden in a residential part of Nerima, the park is built around a large yellow banana-shaped play structure, with banana benches and smaller banana-themed pieces.

This is not a huge destination park with endless facilities, so don’t come expecting a full day of entertainment. Its charm is in how specific it is. A banana slide in a quiet Tokyo neighbourhood is already enough. It’s perfect for a short photo stop, a tiny detour with kids, or anyone building a personal archive of Tokyo’s strangest public design decisions. Bonus points if you bring an actual banana from the conbini and eat it there.

Tachikawa’s Oni Park does not ease you in. Its centrepiece is a giant red demon head with striped horns, heavy brows and an open mouth that children can run straight into. It is part slide, part monster, part public nightmare in the cutest possible way. From the right angle, it looks like the park has been swallowed by folklore, ready to devour you up.

Officially called Nishiki Second Park, this is one of the more famous parks on the list. It has appeared in pop culture, including scenes connected to manga/dramas: Saint Young Men, Gokusen and Nagi’s Long Vacation. The oni is loud, theatrical and very shootable, especially if you want something with more personality than the usual ‘pretty park’ background.

Not to be confused with Iriya near Ueno, this Iriya is in Adachi – and it has a strange, bone-coloured squid-like playground structure that looks like a fossil, a shell, a spaceship and a sea creature all at once. Adachi is famous among playground obsessives for its many ‘tako-san’ slides, but Iriya Central Park is special because it has an ‘ika-san’ slide: a squid, not an octopus.

The park is larger than some of the tiny novelty playgrounds on this list, with a multipurpose ground, play area, swings, a sandpit and standard equipment alongside the sculptural slide. That makes it better for actual playing.
