As of July 2, 2026

We are now offering advance sales of "AirOne," a suitcase that can change between three sizes (S, M, and L) to accommodate the amount of luggage, on the crowdfunding platform "Makuake."

The total amount of support purchased has exceeded 7.8 million yen, with an achievement rate of over 2,600% (as of July 2, 2026).

The project will run until July 30, 2026.

Works like 3 suitcases in 1. Changes to S, M, and L sizes.

On the way there, it's an S size that can be taken into the cabin. If your luggage increases, you can expand it to M or L size on the spot.

When not in use, it can be shrunk to the smallest S size for space-saving storage.

There's no need to own multiple suitcases of different sizes.

- S: Height 54cm / 36L / 1-2 nights [Carry-on size]

- M: Height 62cm / 42L / 3-4 nights

- L: Height 70cm / 49L / 5-6 nights

Suitcase Problems

Do you have these problems?

- It was just the right size on the way there, but on the way back, souvenirs and jackets don't fit.

- Multiple carry-on bags are taking up storage space at home.

- You bring a large suitcase, thinking "bigger is better."

People who travel frequently, such as for business trips or returning home, often face the problem of "the amount of luggage changing between departure and return."

Fixed to 3 sizes with a bottom lock. Telescopes in 3 steps.

Designed to solve common problems encountered on business trips, travel, and at home.

Design Complies with Carry-on Regulations

The smallest size (S size) is designed to be within "55 x 40 x 25 cm" to comply with Japanese airlines.

It is designed to meet the carry-on standards of major airlines such as JAL and ANA. *Carry-on baggage weight restrictions vary by airline. For LCCs (Peach, Jetstar, etc.), the guideline is usually within a total of 7kg, so please check the latest regulations of each company before use. For details, please see the FAQ.

Also for Business. Narrow Handle and Top Handle

The carry bar has a narrow design, allowing you to stack and secure a business bag.

It also features a top handle for smooth storage in overhead compartments and easy lifting on stairs.

Includes a Dedicated Pouch. Standard Features Include Silent Casters and TSA Lock

Created by a Travel Professional with 7 Years of Field Experience

This idea came from 7 years of experience in the travel industry, supporting thousands of travelers annually, and visiting 20 countries around the world.

Witnessing the challenges in the field, such as "luggage changing between departure and return" and "taking up space at home when not in use," I was determined to create a product that would solve them. I began writing down my ideas in a notebook and developing the design.

However, when I started looking for a factory, most of the dozens of companies I contacted were unreceptive.

I finally found a factory willing to cooperate, and sample production began, but it was a continuous process of trial and error.

The first sample had an unbalanced center of gravity, and after repeated modifications up to the third sample, it took over a year.

Even after reaching the final sample, fine-tuning and fixing minor defects continued.

*From left to right: 1st, 2nd. The current version is the 3rd.

Reliable Domestic Support and 1-Year Warranty

Domestic support system provided by a Japanese company. In addition to a one-year warranty, we offer refunds or exchanges for initial defects or incorrect shipments if reported within 14 days of arrival.
