CHIKYU Launches the Exciting Collaboration Backpack with JEF United!

Exciting Collaboration from CHIKYU and JEF United

On March 7, 2026, CHIKYU Corporation, based in Minato-ku, Tokyo, will launch a unique collaboration backpack featuring the popular JEF United theme. This special edition backpack, branded as the Earth NASA Backpack® x JEF United, will be available for pre-order starting at 10:00 AM on the day of the launch. To further engage with fans and customers, an exhibition of this special backpack is scheduled at JEF United's official shop, 12JEF.

Features of the Backpack

The Earth NASA Backpack® x JEF United is not an ordinary backpack; it is customized for club members with several exciting features:

- Safety Reflective Logos: The backpack includes a reflective print of the club logo, ensuring the safety of young athletes on dark, rainy nights.
- Custom Club Design: The underside of the flap is printed with the club’s logo, while name cards and timetable sheets are also tailored for club members.

Pricing and Specifications

- Price: 93,500 yen (including tax)
- Dimensions: Approximately W235 mm × H310 mm × D125 mm
- Weight: Approximately 1,240 grams
- Materials: The backpack is made from Clarino® Efu and artificial leather for the back and underside.

An innovative feature of this backpack is the use of Tempa Foam®, an impact-absorbing material initially developed for NASA’s space shuttle seating. This high-density, low-resilience material ensures that the backpack fits snugly to the child’s body while offering exceptional comfort, moisture absorption, and quick-drying properties.

Innovative Shoulder Strap Technology

Additionally, the backpack incorporates a unique Mirakuru Lock, allowing the pitch width of the shoulder straps to be adjusted to best suit the child's body. This means that as a child grows, the backpack adapts to their changing needs.

Made in Japan Quality

Every CHIKYU backpack is produced in Japan, showcasing a commitment to high-quality craftsmanship. Artisans pay close attention to details, ensuring durability and a sturdy build—proof of its Japanese manufacturing heritage. Furthermore, CHIKYU offers a six-year repair guarantee, ensuring that parents can depend on the backpack over many school years.

Water Resistant Features

The artificial leather used in CHIKYU backpacks is treated for water resistance. It can easily be wiped clean and will not become misshapen or heavy if exposed to water—just be sure to dry it promptly if it gets wet. This allows both the backpack and its contents to remain in pristine condition, ideal for active kids.

The pre-order period runs from March 7, 2026, at 10:00 AM to August 31, 2026, at 11:59 PM. The backpacks will be delivered in February 2027. Orders can be placed through the following platforms:
