(CLAS "Sports & Leisure" list: https://clas.style/sports_leisure/)

CLAS Inc. (Headquarters: Meguro-ku, Tokyo; Representative Director and President: Hirotake Kubo), which operates 'CLAS,' a rental and subscription service for circular furniture and home appliances, will launch its first collaborative campaign with OtoBank Inc., which operates the audiobook distribution service 'audiobook.jp,' starting Friday, May 8, 2026.

As the first phase, they will hold "Home Ear-Activity Walking! with CLAS," proposing "ear-activity walking" – walking while listening to audiobooks using indoor walking machines.

Background of the Collaboration Campaign

'CLAS' has been providing fitness equipment in its "Sports & Leisure" category to enrich a light and personal lifestyle.

Meanwhile, 'audiobook.jp,' operated by OtoBank, has advocated "ear-activity walking" – enjoying "reading while doing" during walking as a healthy habit – and has gained significant support.

However, outdoor walking is often affected by weather, and some people find it a high hurdle if they don't have a regular exercise habit.

Therefore, this collaboration between the two services proposes a new well-being habit that utilizes indoor walking machines, steppers, spin bikes, and other equipment to easily start exercising at home. It aims to provide an unprecedented user experience where one can refresh both mind and body while staying at home.

Campaign Overview

This campaign combines CLAS's furniture and home appliance subscription service with audiobooks provided by OtoBank, proposing a new lifestyle that merges "ear-activity" (learning/reading by ear) and "walking" (exercise).

The special "Ear-Activity Walking Campaign LP" introduces recommended CLAS items that make home exercise more comfortable, including indoor walking machines. It supports creating an environment where one can enjoy "ear-activity" healthily.

What is Ear-Activity Walking?

"Ear-Activity Walking" (or "Ear-Activity Fitness") refers to moving one's body, such as walking, while listening to audiobooks. Joint research by OtoBank and Professor Kenta Shigemori of the Department of Rehabilitation, Faculty of Health and Medical Sciences, Kansai University of Health and Welfare, confirmed that moving the body while listening to audiobooks has a brain blood flow activation effect equivalent to conventional dementia prevention training (*). They advocate "Ear-Activity Fitness" and "Ear-Activity Walking" as dual-task training that can be enjoyed by listening to favorite works.
