About W-STA (Ryansuta)

Ryansuta is a service that allows users to access popular professional mahjong players' content and image rights for a monthly subscription fee. The mahjong industry is growing in popularity due to professional leagues and manga influences, with further growth expected in the future.

By featuring professional mahjong players active in the industry as promotional ambassadors, businesses can enhance brand awareness and contribute to customer acquisition. While talent endorsements typically require substantial investment, Ryansuta's area-based sharing model enables low-cost, fixed monthly pricing—a key advantage.

As long as basic usage guidelines are followed, Ryansuta's provided materials can be used freely in terms of location and method. With almost no restrictive rules, highly flexible promotions are possible. Additionally, since there is no requirement for advertising content review, materials can be used immediately.

Provided Materials

In addition to a wide range of image materials, Ryansuta also provides data of autographed signatures.

Ryansuta offers professional players' image materials, audio materials, and video materials.

Additionally, as original content, materials such as wearing the client's uniform, short scenarios, and original voice recordings are provided based on the contracting company's requests.

*Original content may differ from the above depending on the contract terms.

Optionally, materials featuring professional players wearing your store's uniform are available.

Use Cases

Ryansuta's provided materials can be used for various purposes, including corporate websites, in-store posters, flyers, social media announcements, outdoor promotions, and video promotions.

Future Direction

Pac-Ex Co., Ltd. has extensive business relationships with numerous amusement and pachinko-related companies through its human resources services and customer acquisition support. Therefore, the company will initially focus on providing services to amusement and pachinko-related businesses.

However, Ryansuta's provided materials are highly versatile and applicable across industries and occupations. Therefore, in the future, the company aims to serve a wide range of industries and become a bridge between businesses and the mahjong industry.

Additionally, the company actively promotes collaboration with advertising agencies and sales partner companies who can jointly expand media value.
