Shima Green Adventure, which will celebrate its second anniversary in July of this year, is hosting a collaborative event with "Space Brothers" called "Space Brothers: Aim for Astronaut Mission Rally in Shima Green Adventure ~we are space brothers~" from July 17th, 2026 (Friday).

During the event period, visitors can enjoy special content that can only be experienced here, such as a collaboration room that recreates the world of "Space Brothers," a mission rally where visitors take on the role of astronaut trainees, park decorations, photo spots, original announcements, and official merchandise sales.

This event is enjoyable not only for fans of "Space Brothers," but also for families and friends.

Immerse yourself in the world of "Space Brothers"! Collaboration Room

At the "Glamping Field," one premium dome and one premium dog dome are available as collaboration rooms themed after "Space Brothers."

The guest rooms are decorated with scenes from the manga, and standee panels of the main characters, Mutta Nanba and Hibito Nanba, are on display.
Furthermore, you can collect all the volumes of the manga and spend a special time immersed in the world of "Space Brothers."

The Premium Dog Dome also features a photo spot with the protagonist's beloved dog, Apo, where you can enjoy taking commemorative photos with your own dog.

Additionally, guests staying at the property will receive a set of four original can badges as a gift per building.

Become an astronaut trainee and take on missions!

We are hosting an original mission rally at the attraction field.

Take the "Mission Rally Book" you receive at the Welcome House or entrance gate, explore the park, and choose your favorite course from the three available mission courses to take on the challenge.
By completing missions, you can collect stamps and receive an original, event-exclusive pin badge as a reward.
There are a total of 8 types of can badges across both the first and second releases, and they will be distributed randomly.

Here's a glimpse of the mission content.

Intensive Training Course

Challenge yourself on special courses inspired by "Mutta Nanba," "Hibito Nanba," and "Apo" in the world's first two-building, large-and-small-sized connected athletic tower. Enjoy thrilling athletic challenges while completing missions.

Kids Mission Course

This course involves collecting collaborative stamps hidden in the maze "Green Maze" to complete a picture. Adults and children alike can enjoy searching for "Apo" hidden throughout the park.

Light training course

This is a photo mission where you take pictures at a designated photo spot, striking the same poses as the characters from "Space Brothers."

A fun summer mission has also been added.

"Green Splash," which debuted last summer, is making a comeback as "Space Splash" in collaboration with "Space Brothers."
This summer-only water play attraction takes place on a large lawn area, where you can avoid floor fountains while using water cannons and water guns to attempt a mission to make contact with a UFO.
From children to adults, let's get soaked and beat the summer heat!

Experience the world of "Space Brothers" at various locations throughout the park.

The park will feature standees of characters such as Nanba Mutta and Nanba Hibito, as well as photo spots, banners, glass decorations, and more, creating an immersive experience of the world of the series.

Additionally, original announcements by Hiroaki Hirata, the voice actor for the main character Mutta Nanba, will be broadcast throughout the park, allowing visitors to enjoy an experience that makes them feel as if they've stepped into the world of the story.

Limited edition merchandise will be available for purchase, and there will also be a craft workshop!

Welcome House is selling official Space Brothers merchandise in limited quantities.
The collection includes must-have items for fans, such as acrylic stands, clear files, and tote bags.

Furthermore, rocket and original planet-making workshops are held exclusively on weekends and holidays.
