Transforming Hearing Aids into Stylish Accessories! For Nail Salon Owners Nationwide Franchise Opportunities Now Available!

The salon also contributes to society through the skills of manicurists!

合同会社 Studio KAI

COCO H.A., a brand specializing in hearing aid covers, has now begun accepting franchise applications for nail salons. The brand uses nail art technology to transform and dress hearing aids into fashionable accessories, enabling both the avoidance of risk of economic loss for the elderly and socially vulnerable and the improvement of store productivity and profitability.


「静かな世界に、メロディを響かせる」

In a quiet world, a melody echoes."


[Providing peace of mind and fashion for hearing aid users and their families].

There are approximately 2 million hearing aid users in Japan. However, they are often embarrassed by their conspicuous appearance, easy to drop, and fragile.

COCO H.A.'s hearing aid covers solve these problems and make wearing hearing aids more comfortable and attractive.

We will create an original hearing aid cover just for you.


Product Features

Fashionable: Hearing aid covers that can be enjoyed like jewelry

High-quality design: Production and fitting service by a domestic manicurist at the first or second level or higher

Loss and damage prevention function: Optional strap design prevents loss and damage due to dropping.



[World's first business model! Trademark registration and patent pending hearing aid covers]

COCO H.A. hearing aid covers are produced using COCO H.A.'s unique manufacturing method. It is a registered trademark and this manufacturing method is currently patent pending. This business model is attracting a great deal of attention as the first in the world and the first in Japan to commercialize the production and sale of hearing aid covers for nail salons.

Member nail salons can introduce the system at low cost by utilizing their existing facilities and nail technology. This is a great way to secure a new source of revenue while making effective use of manicurist's spare time.



Nail salons can apply nail technology to create high quality designs.

Currently, it is said that more than 90% of nail salons go out of business within 5 years of opening, and last year the number of nail salon closures was the highest ever.

A's Member Shop System is an innovative system that provides nail salons with new business opportunities and overturns the conventional wisdom of this industry.

Member nail salons can secure a new source of revenue through the production and sale of hearing aid covers. Since they can be produced using the same technology as existing nail tips, the hurdles to introducing the system are low, and the off-peak hours of the salons can be effectively utilized.

Nail salons can operate without changing their store names or brand names.
