Automatic Retractable Shoulder Belt 'Makitorikun' Achieves Remarkable Success

In a remarkable showcase of consumer interest, the automatic retractable shoulder belt known as 'Makitorikun' rapidly sold out within just 18 hours of its launch on the crowdfunding platform Makuake. Developed by Wataki Shoko Co., Ltd., a leather goods manufacturer located in Sumida Ward, Tokyo, the project ended with an impressive total funding of 1,534,726 yen, with 265 units sold and an astonishing achievement rate of 1,534%.

Key Highlights of the Project

• - Fast Selling: The initial offering of 100 units was smashed in less than a day, which prompted the company to quickly ramp up production to meet the overwhelming demand.
• - Final Total: The crowdfunding campaign wrapped up with 225 backers and was completed on November 15, 2025, showcasing a clear indication of the product’s popularity in the market.

Development Background

Founded in 1959, Wataki Shoko started as a small factory specializing in leather goods. The company tackled everyday inconveniences faced by users, such as cumbersome shoulder belts that often droop, tangle, or get dirty. By aiming to redesign this common product, they crafted an automatic retractable mechanism that efficiently resolves these issues.

For roughly two years, the team experimented with various elements, including the gear structure, locking strength, and spring characteristics, ultimately creating a device that allows for one-handed length adjustments and automatic retraction for storage when not in use.

It is noteworthy that this development was not merely an OEM endeavor. The process was entirely self-initiated, allowing Wataki to gauge market demand through their crowdfunding approach. The immediate sell-out of the product dramatically validated their efforts.

Insights from the CEO

Hiroyuki Watanabe, CEO of Wataki Shoko, stated, "This project has proven that even a small manufacturing firm can create new 'norms' that address everyday inconveniences." The primary motivation behind the invention was the desire to create an optimal solution for the everyday annoyances of drooping, tangling, and dirtiness that traditional shoulder straps present. With no suitable products available in the market, he and his team committed to developing a better solution.

In the end, the reception and support from users during the crowdfunding campaign have been an immense encouragement for the company, reinforcing their belief that, with careful design and incremental improvements, small-scale manufacturers can introduce market-friendly products.

Future Plans

Following the successful crowdfunding campaign, Wataki Shoko plans to release the product through various online retail channels, including Amazon and Rakuten. Fulfillment for crowdfunding backers is slated to begin in January 2026.
