Tsunagaru Kagaku Kenkyujo Announces Tokyo Office Relocation

Tsunagaru Kagaku Kenkyujo Inc. (Headquarters: Osaka, Osaka Prefecture; President & CEO: Tsutomu Nakagawa), which provides Web marketing and SNS marketing support, has independently relocated its Tokyo office to the Shinjuku Gyoen area as of April 1, 2026, due to business expansion.

Background of the Relocation Previously, our company shared an office with our group company, GP Online Inc. However, in recent years, consultations from clients in the Tokyo metropolitan area have rapidly increased, and the number of Tokyo office members has grown to exceed that of our Osaka headquarters. Due to a shortage of space and the necessity to establish functions as a central hub, we decided on this independent relocation.

The new location in the highly convenient Shinjuku Gyoen area will enable us to provide even higher quality services.

Features of the New Tokyo Office Adjacent to Shinjuku Gyoen, the office offers a calm environment with abundant greenery. We chose this location as a place where our members can focus on addressing client challenges.

Comment from Representative Director and President, Tsutomu Nakagawa The world of the web is changing rapidly, but what we consistently value is the perspective of 'what kind of relationships are formed beyond delivering information.' We consider our work to be not only content creation and operation but also supporting companies and users in building long-lasting, positive relationships.

Until now, our Tokyo office was based in our group company's office. However, in recent years, the Tokyo office has become central to our company in terms of both scale and role. This relocation is in line with that reality.

At the new location, we aim to combine our team's creativity with our digital marketing expertise to become a presence that can be more deeply involved in building relationships between our clients and their users.

About Tsunagaru Kagaku Kenkyujo Inc. We, 'Tsunagaru Kagaku Kenkyujo,' are a group of professionals who provide digital marketing support for client companies from a content perspective, originating from 'GP Online,' a digital creative company based in Kansai.

With the mission to 'Change expressions, change relationships, and become the driving force for business growth,' we offer one-stop support from planning to content creation and analysis for social media and owned media, including SNS operation代理, SEO consulting, and web content production.
