Crescent Co., Ltd. (Headquarters: Nishinari Ward, Osaka; President: Masatoki Goshimoto; hereinafter "Crescent") is pleased to announce a collaboration project between its new functional business shoes "Bizppa" (which feature a foldable heel) and the popular manga series "Kouzakushima" by Kenshi Hirokane. The collaboration will commence on July 1st, 2026 (Wed).

Bizppa are innovative functional business shoes created with the concept of "bringing a sense of freedom to the feet of working men." While maintaining a professional appearance as business shoes, they can also be worn like slippers by folding down the heel, supporting the feet of modern businessmen who transition between "combat mode" and "relaxation" during client visits, business trips, and Shinkansen travel.

This collaboration brings together Bizppa and the "Kouzakushima" series, which has been cherished by many businessmen for years. It expresses the "balance of work and rest" of a capable man – fighting when necessary, resting when needed – from Bizppa's unique perspective.

Bizppa: Supporting Your Moments of "Wanting a Little Ease" During Client Visits, Shinkansen Rides, and at Your Doorstep

Bizppa was developed as "a pair of shoes that allows you to switch between on and off without changing them," focusing on the habit of businessmen to "wear business shoes for commuting and change into slippers in the office."

Developer Crescent Co., Ltd. leverages its commitment to comfort, cultivated through making women's shoes, to propose business shoes that differ from the conventional image of being "stiff and constricting."

Initially intended for use within the office, after their release, they have also been utilized by businessmen who travel frequently on Shinkansen and airplane for business trips, as well as by those in professions requiring frequent shoe changes, such as visiting care providers, movers, and real estate agents conducting property viewings.

Many repeat customers say, "Once I wear them, I can't wear anything else." Based on user feedback, improvements have been made to the soles and cup insoles, evolving them into specifications that are comfortable for outdoor wear.

Collaboration Realized with "Kouzakushima," the Symbol of the "Working Man"

This collaboration partners with the "Kouzakushima" series, which has been loved by many business professionals for over 40 years.

"Kouzakushima" is a symbol of the "working man," supported by businessmen for many years, and has high affinity with modern business scenes involving client visits, business trips, and travel.

Bizppa offers more than just "comfortable shoes."

It is a pair of shoes that naturally supports the "balance between on and off" from your feet, allowing you to relax slightly during office hours and travel, and then switch gears for negotiations and public appearances.

The approach is to accumulate achievements by moderately relaxing rather than constantly being on edge. This way of working also mirrors the journey of the protagonist, Kouzakushima, who has had a long career.

For this collaboration, original illustrations by Kenshi Hirokane have been created. Furthermore, a collaborative manga content that allows you to enjoy the world of "Kouzakushima" is also available on the special website.

About "Kouzakushima"

The "Kouzakushima" series (by Kenshi Hirokane) depicts the business world and the lives of working people through the ages, as the protagonist Kouzakushima progresses in his career from section chief to general manager, director, president, chairman, and outside director.

The series has surpassed 47 million copies in total circulation and has been cherished by many business professionals for over 40 years.

It portrays how characters approach their work, their relationships with others, and the changing nature of work over time, making it a work read across generations.
