Midosuji Daibiru Building
The Midosuji Daibiru Building is a next-generation office building that faces on Midosuji, one of Osaka's main streets, in an excellent location overlooking the greenery of the Namba Shrine. With "Your Premium, You Workplace" as its concept, the building provides workplaces that can respond to the diversification of working styles and an interior environment that supports physical and mental health. Daibiru values the philosophy of being in harmony with nature, which has been handed down within the company, and has implemented measures to reduce environmental impact and strengthen business continuity planning (BCP) in preparation for a disaster, resulting in acquisition of an S rank, the highest level of the CASBEE Smart Wellness Office certification program.*1 We also received a five-star rating, the highest level, under the Building-Housing Energy-efficiency Labeling System (BELS) and obtained ZEB Oriented certification*2 for the office areas.

- *1CASBEE Smart Wellness Office is a program that combines CASBEE Wellness Office certification with an environmental performance assessment of the building (in the case of the Midosuji Daibiru Building, CASBEE Osaka Mirai certification). CASBEE Wellness Office is a tool for assessing the specifications, performance, and measures of buildings for supporting the maintenance and enhancement of the health and comfort of building users. In addition to factors that directly impact the health and comfort of the individuals who work in the building, factors that contribute to the enhancement of intellectual productivity as well as performance relating to safety and peace of mind are evaluated.
- *2ZEB Oriented is a certification program that covers building with a gross floor area of at least 10,000 square meters that have high-performance exterior structures and high-efficiency energy-saving facilities and implement measures to achieve further energy savings. Decision-making criteria relating to energy consumption are defined as the reduction in primary energy consumption specified from standard primary energy consumption, excluding renewable energy, for each applicable use (in the case of offices, schools, and factories, reduction of at least 40%, and in the case of hotels, hospitals, department stores, restaurants, and assembly halls, reduction of at least 30%). The scope of the ZEB Oriented certification of the Midosuji Daibiru Building is "offices."
Yaesu Daibiru Building Reconstruction Plan
This project involves the construction of the Company's Tokyo-region flagship office building in a premium location that is near Tokyo Station and is directly linked by an underground passageway to the Yaesu underground shopping area. Demolition of the former Yaesu Daibiru Building was completed in March 2023, and construction of the new building is now underway.
The new building will maintain the value of the former building and feature a distinguished design and green space open to the community and public, expressing its timeless presence and contributing to the creation of a new cityscape in Yaesu as redevelopment in the area progresses. We are taking measures to curtail environmental impact in response to climate change and have formulated a BCP in preparation for a disaster, and we plan to obtain S rank of the CASBEE Wellness Office*3 certification as well as Gold of the LEED certification, a U.S. building environment certification program. We also expect to obtain a five-star rating under the BELS program and ZEB Oriented certification for the office areas.
