Background of the Merger

RJ Office boasts a highly precise PM/BM system specialized in the micro-office domain and high-quality operational capabilities that capture latent on-site needs. It has built strong trust and a solid track record from both sides: as a strategic partner supporting revenue maximization for real estate owners and asset management companies, and as an office operation partner realizing desired spaces and environments for users.

BLOCKS PLUS was established with the aim of integrating RJ Office's operational know-how with Profittz's content planning capabilities and asset management functions (Reference: Press release distributed on March 7, 2022: "Establishment of 'BLOCKS PLUS Co., Ltd.' to develop new types of shared offices tailored to needs").

Since its establishment, it has expanded its presence by developing "BLOCKS OFFICE," a new type of shared office that transcends conventional concepts, utilizing unique branding and leasing methods (https://www.blocks-office.jp/).

Against the backdrop of this business expansion, as the business enters its next growth phase, both companies shared the recognition that strengthening the management foundation in line with business growth, such as optimizing human resources and enhancing operational sophistication, is crucial for further expansion and growth.

Based on this challenge, both companies agreed that integrating their planning and operational functions and creating business synergies by leveraging each other's strengths would accelerate growth, leading to this merger.

Future Vision

The new RJ Office, with this merger as a new starting point, will proceed with building a robust management foundation that flexibly adapts to changes in market conditions. By vertically integrating planning and operational execution even more closely, it will achieve faster decision-making and stronger business promotion capabilities, establishing a system where needs identified on-site can be immediately reflected in planning.

Through this system, we will strive to create new value as a leading company providing office solutions that respond to next-generation work styles. Furthermore, looking ahead, we aim to expand our business domain even further, not limited to work styles, but also considering the deployment of operational services to various assets aimed at "improving people's QOL (Quality of Life)."

Comment from Koji Kishida, Representative Director of RJ Office Co., Ltd.

This merger will enable us to develop shared office businesses that respond more quickly and flexibly to market needs under an integrated planning and operation system. We will continue to provide office solutions that support new work styles while catering to the diverse working styles of our users.

Profittz will continue to work closely with the new RJ Office as a strategic partner, aiming to become a corporate entity trusted by all stakeholders and growing together.
