Announcement of Company Name Change and Business Transformation: Toshoko Housing Co., Ltd. Becomes '971 Corporation' — Launching Operations of 'Penguin Suido,' a Water Emergency Service in Saitama Prefecture through Integration with RavirHoldings

Background of Business Integration and Name Change

Previously operating as 'Toshoko Housing Co., Ltd.,' the company has supported customers by providing junk removal and estate clearing services (brand name: KATAZUKE-YA HIKYU).

Now, through integration with RavirHoldings, the company has made a strategic shift to focus on protecting people's daily infrastructure more directly and swiftly. As part of this transition, it is exiting its previous business and fully taking over the emergency plumbing and facility services previously operated by RavirHoldings under the brand 'Penguin Suido.'

At the same time, the company is relocating its base to Saitama Prefecture, changing its name to '971 Corporation (pronounced: KUNAI),' and launching a new chapter under the leadership of CEO Yu Sakurai with a stronger organizational structure.
