Mitsui Fudosan Co., Ltd. (Headquarters: Chuo-ku, Tokyo; Representative Director and President: Shun Ueda; hereinafter 'Mitsui Fudosan') and Sumitomo Mitsui Banking Corporation (Head Office: Chiyoda-ku, Tokyo; President & CEO: Akihiro Fukutome; hereinafter 'SMBC') have obtained certification for the 'Hakata Connected Bonus*1' and 'Green Bonus*2' for the 'Hakata New Mitsui Building Redevelopment Plan' (hereinafter 'the Plan') located at 1-1, Hakata Ekimae 1-chome, Hakata-ku, Fukuoka City, Fukuoka Prefecture. This Plan is the first in Fukuoka City to receive simultaneous certification under both systems.

The Plan will implement initiatives promoted by Fukuoka City, such as 'Hakata Connected*3', 'The 10,000 Trees Project for the City Center Forest*4', and 'Fukuoka Art Next*5', contributing to further enhancing the appeal and international competitiveness of the Hakata Station area.

The Plan contributes to creating local vibrancy by applying three-dimensional greening to the highly visible wall facing Hakata Station and by arranging plazas that enhance the area's walkability. It realizes next-generation offices that prioritize comfort and environmental considerations.

■ Three-dimensional, abundant green exterior design rising vertically facing Hakata Station

By incorporating diverse greenery such as medium-to-high tree planting and hanging plants on balconies facing Hakata Station, along with abundant greenery on the lower floors, the building will feature a three-dimensional green exterior design (Vertical Green) that rises vertically from the ground, planned as a new landmark in front of Hakata Station. On the ground-level plaza, highly symbolic pillars will be placed, featuring a design that combines vertical lines of aluminum panels with varied expressions, changing impressions depending on the direction of walking and viewpoint, with greenery that changes with the seasons. Additionally, a带状 wall greening will be applied on the second-floor level, connecting with surrounding buildings and adding color to the pedestrian network space.

■ Grand staircase and plaza to enhance walkability around Hakata Station, creating relaxation and vibrancy

In the Plan, the underground plaza will be directly connected to Hakata Station via the Hakata Station underground shopping street. A ground-level plaza capable of hosting events will also be developed on the first floor, creating connections and expansiveness with the surrounding area, aiming to generate relaxation and vibrancy. Elevators and escalators connecting these ground and underground plazas in a barrier-free manner will improve convenience for visitors. Furthermore, the grand staircase connecting the underground and ground levels will feature abundant greenery and public art, along with benches providing resting spaces, creating a comfortable environment where visitors can easily linger.

■ Provision of high-quality office spaces

A rooftop lounge exclusively for tenants will be provided on the roof, and on the southeast side of each floor, tenant-exclusive balconies will be arranged from which the greenery of the Vertical Green exterior can be viewed from inside. In an open space overlooking Hakata Station, the plan offers an environment where tenants can comfortably spend time, taking breaks or refreshing themselves between work.

■ Environmentally conscious initiatives

The Plan aims to achieve ZEB Ready certification (for office use portions) and 'CASBEE Fukuoka A Rank' towards realizing a decarbonized society. Additionally, by using wood for the soffits of the plaza and the benches installed on the grand staircase and plaza, the plan aims to fix carbon dioxide while creating spaces where nature can be felt close at hand.

As the city undergoes major transformation through building redevelopment, it aims to add 'color' to the city and create spaces for relaxation and tranquility through the appeal of greenery.

■ Mitsui Fudosan Group's Sustainability

The Mitsui Fudosan Group, based on the philosophy of the '& Mark' – 'Creating new value through symbiosis, coexistence, and co-creation, and continuing to challenge for that purpose' – views 'creation of social value' and 'creation of economic value' as two sides of the same coin. It believes that creating social value leads to the creation of economic value, and that economic value enables the creation of even greater social value.

When formulating the new group management philosophy in April 2024, the group identified six 'GROUP MATERIALITIES (priority issues)': 1. Contribution to industrial competitiveness, 2. Coexistence with the environment, 3. Health and vitality, 4. Safety and security, 5. Diversity and inclusion, and 6. Compliance and governance. The group will address these materialities through its core business and contribute to sustainability.
