A Private Office Where Business and Life Shine
The concept behind 'Gran-S' is a "private office where business and life shine." More than just providing a workspace, Gran-S offers a "trusted infrastructure" equipped with robust information security and fully soundproof private rooms—this is why professionals have consistently chosen Gran-S.
As more tasks are completed online, the choice of "where to speak" and "where to think" directly impacts the quality of work. Ensuring time that no one can overhear, see, or interrupt is essential.
The design allows users to reserve only the time they need, optimized for professionals who understand the value of time.
Just 5 Minutes from Higashitotsuka Station: A Work Option Close to Home
Located a 5-minute walk from Higashitotsuka Station on the JR Yokosuka and Shonan-Shinjuku Lines, this space is convenient not only for commuters traveling between Yokohama and Tokyo but also for those who need a focused environment near their homes.
Having a third workspace option between working from home and commuting to the office—Gran-S has served precisely this role.
Three Fully Soundproof Private Rooms: Ideal for Confidential Work, Business Meetings, and Deep Thinking
The Gran-S workspace features three fully soundproof private rooms (for one person each), in addition to open coworking desks and semi-private booths that balance focus and openness.
In these private rooms, professionals can conduct online client meetings, handle documents containing confidential information, provide coaching, or articulate strategies—ensuring privacy and uninterrupted concentration in any situation where "being overheard" or "losing focus" is unacceptable. The quality of the space protects the quality of the work.
A Premium Environment Designed for Professionals
The space is equipped with coffee and water dispensers, free drinks, high-speed Wi-Fi, power outlets at every seat, and separate restrooms for men and women—providing all essential amenities for long-term use.
Since opening, we have consistently maintained a space quality that goes beyond "a place to get work done"—a place people genuinely want to visit specifically to work.
[Message from the Representative] Yoko Yamazaki, Representative Director, Justice Co., Ltd.
As options for where to work expand, the era has arrived where "where you work" determines the quality of your work. 'Gran-S' is a private office designed specifically for those handling highly confidential tasks and those who need dedicated time for deep thinking. The fully soundproof private rooms function not only to prevent your voice from leaking out but also to shut out external noise—serving as a "vessel for concentration."
Thanks to this system integration with Ii-Office, business professionals across Japan who previously did not know about Gran-S now have greater access to this space. We aim to remain a space that every individual who values the quality of their work will choose.
