Shosukabu.com Launches 1-Year Train Strap Advertising Campaign on Osaka Metro Midosuji Line

Shosukabu.com Co., Ltd. (Representative Director and Chairman: Yutaka Yamanaka, Head Office: Nerima-ku, Tokyo, hereinafter referred to as "the Company") announces that it has commenced a one-year "Strap Advertising Campaign" exclusively utilizing straps inside trains on the Osaka Metro Midosuji Line from Thursday, June 11, 2026, to Thursday, June 10, 2027, as detailed below.

Following previous campaigns at Tokyo Metro Kasumigaseki Station, Hongo-sanchome Station, and Tama Monorail Takamatsu Station, this is the Company's first large-scale transportation advertising campaign in the Kansai area. Along the Midosuji Line, which accommodates the Osaka High Court, District Court, and Summary Court (around Yodoyabashi and Oebashi stations) and boasting the highest passenger volume in western Japan as "Osaka's main artery," the Company aims to rapidly increase awareness as a specialized partner for the sale and liquidation of unlisted minority shares.

1. Background of the Campaign

The Company has strategically promoted advertising campaigns in key areas in the Tokyo metropolitan area where legal hubs and specialists gather. The current campaign on the Osaka Metro Midosuji Line aims to expand service awareness in western Japan and reach shareholders facing potential challenges.

The Midosuji Line traverses major business districts in Kansai, such as Yodoyabashi and Honmachi, as well as bustling shopping areas like Umeda and Namba, making it one of the busiest subway lines in Japan. In addition, courts are located along the line, and it is routinely used by many legal professionals, businesspeople, and wealthy individuals.

By launching a year-long train advertisement "Strap Advertising Campaign," which naturally catches the attention of passengers, the Company hopes to encourage search behavior via smartphones and firmly establish the fact among people in Kansai that "unlisted shares (minority shares) can be sold and liquidated early at a fair price with an appropriate scheme."
