Seibu Real Estate and LOOPLACE Collaborate on Yuusha Ohta Building Upgrade

Seibu Real Estate Co., Ltd. and LOOPLACE Co., Ltd. have recently completed a significant upgrade project for the Yuusha Ohta Building, located in Bunkyo City, Tokyo. This collaboration is part of Seibu's long-term strategy to maximize real estate value as outlined in their 2035 growth plan. The completion of this project marks a pivotal step in their value-added business initiatives.

Project Overview

The Yuusha Ohta Building, constructed 33 years ago, was acquired by Seibu Real Estate in February 2025, with a clear goal of enhancing the asset's value. LOOPLACE, based in Chiyoda, Tokyo, was responsible for marketing research, design and construction, as well as managing the completion viewing event, set to take place on July 4, 2025. This event will showcase the building’s new features, which include upgraded office spaces and amenities tailored to attract tenants, particularly from the medical and research sectors.

Transformation Details

The renovation of the building includes several impressive enhancements. A new shared lounge area will be available to tenants, featuring an innovative L-shaped sofa layout designed to facilitate relaxed interactions while avoiding face-to-face seating. The new setup encourages collaboration without compromising comfort. Furthermore, improved meeting rooms equipped with versatile desk arrangements have been designed to accommodate various working styles effectively.

The design concept, titled "BIOPHILIC LABORATORY", integrates natural and industrial materials, reflecting the building’s educational and research-focused neighborhood, especially with nearby institutions like the University of Tokyo and Juntendo University. By applying biophilic design principles, the renovation aims to promote well-being and engagement among workers, creating an inviting and productive atmosphere.

Event and Access Details

The completion viewing event is set for July 4, 2025, from 10:00 AM to 5:00 PM (last admission at 4:30 PM) at the Yuusha Ohta Building on the 6th and 7th floors. The building is conveniently located a 7-minute walk from Honkomagome Station on the Marunouchi Line and an 8-minute walk from Yushima Station on the Chiyoda Line.
