IINO Building

Significant Upgrade in Energy Efficiency due to High Environmental Performance

The IINO Building features advanced equipment and technology in order to maintain comfort while using much less energy. Key aspects include the use of LED lighting as base lighting on all office floors, desiccant air-conditioning, a double-skin external facade on all four sides, and natural ventilation using eco-voids. These features will enable the use of significantly less energy across the building.

Disaster Preparedness including Superior Earthquake Resistance and Business Continuity Plan Measures

The IINO Building was built with the safety of its users at the forefront of all considerations, and has superior earthquake resistant features.
In order to help tenants with their business continuity planning, the building has emergency-use power generators capable of running in common areas for 72 consecutive hours. In addition to the space on the roof of the building for tenants to install their own emergency use power generators, an emergency generator is separately installed to supply electricity to the tenants' private areas.

Connection with the Surroundings

The basic concept behind the reconstruction was "to connect." Underground passageways were built to connect the IINO Building with neighboring office buildings, the Kasumigaseki subway station, and the Hibiya City underground shopping mall, as well as with the Uchisaiwaicho subway station.
A green belt named 'IINO Forest' (called IINO no mori in Japanese) is built in the open space between the IINO Building and Hibiya Park, which is located across the street, thereby creating a relaxing green space linking the two.

IINO Dining

IINO Dining, a refreshing oasis in Kasumigaseki. Here, guests can casually drop in to experience a soothing, warm and welcoming atmosphere for lunch or to relax after work, have a drink with colleagues or a girls' night out, a holiday family visit, or any number of other scenarios.

The Revival of IINO Hall

The opening of the new IINO Building is accompanied by the revival of the much-adored IINO Hall, which will carry on traditions while also featuring a conference venue.
Like the former IINO Hall, the new hall will host a wide range of events, including Japanese comic storytelling, Japanese music and classical music performances, movie showings, speaking engagements and ceremonies. The conference center is on the same floor, allowing simultaneous use of both IINO Hall and the conference center.

Using Art to Create a Rich and Tasteful Environment

Artwork consistent with the building's design will be placed throughout the building and grounds to create a rich and tasteful environment.
In addition to relocating the murals which decorated the walls of the former IINO Building to the new IINO Building, a wide range of artwork from various genres of modern artists, from up-and-coming Japanese artists to famous international artists, will be used to give the building character.

Former IINO Building (1960 ~ 2008)

Iino Fudosan Kaisha Ltd. was established in 1953 (merged with IINO Kaiun Kaisha, Ltd. in 1997) to manage the rea1 estate business and construction on the former IINO Building began in December 1958, and the building opened in 1960. Based on the design concept of "Sublimely Modern," this large-scale leasing building was constructed using the latest architectural technology of the time.
It was also noted for its progressive orientation toward the dissemination of culture through the establishment of IINO Hall. Until its temporary closure in 2007, the hall had hosted 16,000 performances and a total of approximately 8 million visitors. During that time, it had been used for numerous events such as movies, music recitals, rakugo, theater, Japanese dance, traditional arts performances, seminars, and lectures, playing a role as a cultural promoter.
For over 40 years, the IINO Building witnessed steady changes in Tokyo and Japan. In 2008, we began a rebuilding project with the aim of providing even safer, more comfortable offices, commercial facilities and IINO Hall.

IINO Building was designed to be a cherished landmark for a century to come (2011 ~)

The former IINO Building featured a stately but modern design which made it a familiar Tokyo landmark. The building was constructed at a time when convenience was a priority. As times changed, society developed a heightened awareness of the need for improved security, environmental consciousness, and emergency responsiveness. We made a decision to rebuild the building with the realization that a transformation was needed to meet emerging needs of the future.
At the same time, we also ensured a "connection" between the old and the new by re-exhibiting a distinctive wall relief and reusing the marble from the former IINO Building.
Construction on the new IINO building began in 2008 and was completed three years later, when the building opened for business in October 2011. After a second phase of construction, the completed the building held its grand opening in November 2014.
The building has cutting-edge, outstanding environmental performance, and has received various evaluations and certifications, including LEED Platinum Certification and DBJ Green Building Certification*. In addition, the IINO Forest established on the site contributes to the preservation of biodiversity by planting many tree species, including indigenous species, throughout the entire planting plan.
Through the IINO Building that has provided a rich connection to society, we will continue to respond to the social needs of any generation, and it is our hope the building is cherished 100 years into the future.
