1.Outline of robot services at Tokyo Midtown Yaesu

■ Delivery robots

Food delivery services are becoming popular amid the COVID-19 pandemic. Up until now, delivery people have delivered the orders in places like office building lobbies from the perspective of security. For that reason, people working on upper floors have experienced the inconvenience of going down to the lobby to receive their orders.

At Tokyo Midtown Yaesu, Mitsui Fudosan will for the first time introduce a service in which robots receive the orders from delivery people in the lobby and deliver them directly to office workers. This will improve convenience for office workers while also contributing to COVID-19 countermeasures by eliminating contact between the office workers and delivery people. This service will also be available for delivery of takeout items from the eating and drinking establishments located within the Tokyo Midtown Yaesu building.

■Cleaning robots

Mitsui Fudosan has promoted the use of cleaning robots, etc. at its existing offices from the perspective of addressing labor shortages. However, up until now, it was necessary for people to accompany the robots during their movement through the office buildings, and Mitsui Fudosan was unable to fully achieve labor savings. At Tokyo Midtown Yaesu, Mitsui Fudosan has been working with the architect/builder TAKENAKA CORPORATION to construct a robot-friendly building. Robotics enable the user to designate to the elevator the floors for getting in or out, which achieves complete labor savings.

■ Carrying robots

Using Carrying robots will make it possible for anyone to move heavy cargo for shipping operations, allowing more diverse personnel to work. In this way, Mitsui Fudosan will promote the realization of a society in which possibilities for people expand through technology such as robots, which is part of the “Society 5.0” promoted by the Japanese government.

Prior to introducing these robots to Tokyo Midtown Yaesu, Mitsui Fudosan conducted a demonstration experiment within its own office at Nihonbashi Muromachi Mitsui Tower.

2.Initiatives for “real estate as a service” envisioned by Mitsui Fudosan at Tokyo Midtown Yaesu

“Real estate as a service” refers to neighborhood creation that perceives neighborhoods not as facilities or things, but as a service that offers human activity such as working, playing, and living. At Tokyo Midtown Yaesu, Mitsui Fudosan is undertaking initiatives to achieve “real estate as a service” using cutting-edge technology. For instance, as the first completely contact-free office building among large-scale office buildings in the Tokyo metropolitan area, the introduction of systems to enter and leave offices using facial recognition and automation of doors at entrances to private areas will enable office workers to enter offices comfortably and hands-free without any direct contact at all.

Mitsui Fudosan has also advanced discussions to use robots in order to promote digital transformation (DX) within office buildings. At this facility, Mitsui Fudosan has enabled transmission and coordination between robots and elevators and security doors to achieve vertical and horizontal robot movement, which had previously been a major obstacle to introducing robots at office buildings, in addition to the active utilization of automated doors. As a result, Mitsui Fudosan will achieve fully autonomous robot movement and launch not only demonstration experiments but the full-scale introduction of robot usage starting with this facility. The Company will also give consideration to the safety and security of office workers when robots are engaged in fully autonomous movement and aim to create a robot-friendly office building where possibilities for people expand through robots.

Mitsui Fudosan will also proactively introduce various initiatives harnessing 5G going forward. Through these types of cutting-edge efforts, the Company provides office workers with premium business lifestyles.

3.Overview of robots and robot-related applications to be introduced at Tokyo Midtown Yaesu

RICE can be used not only to deliver items, but for purposes such as leading and guiding customers as well.
    RICE has been designed based on the assumption that it will work in harmony with people, and is equipped with functions to avoid collisions with people and obstacles. By coordinating the robot with the elevator, it is also possible to deliver cargo to different floors. The robot is also notable for featuring a design that makes it easily approachable without any feelings of hesitation, and has been designed with similar attitudes in regard to UI/UX.

  • RULO Pro cleaning robot from Panasonic Corporation
    The RULO Pro cleaning robot will automate floor cleaning, primarily in the common areas of office buildings. Through four types of sensors, RULO Pro will effectively clean the total floor area along the wall and reduce labor in pursuit of usability by, for example, employing a method using paper bags to dispose of garbage.
    The robot is equipped with long-distance laser sensors which make it suitable for even large spaces such as entrance halls or conference rooms.

What is Tokyo Midtown Yaesu?

Tokyo Midtown is the brand name for Mitsui Fudosan’s urban mixed-use neighborhood creation projects that harness the Company’s total capability. Since its debut in 2007, the Tokyo Midtown brand announced its vision of “a town that creates and brings together JAPAN VALUE (new value, sensibility and talent) and continues to disseminate such to the world.” Tokyo Midtown delivers the four common values of diversity, hospitality, creativity, and sustainability in its neighborhood creation projects.

Tokyo Midtown (Roppongi) (opened in Akasaka, Minato-ku, in 2007) has so far created new value by combining diverse talent concentrated in the neighborhood, and has come to embody a vision for the neighborhood through careful consideration and hospitality toward people visiting the area, seasonal events utilizing rich, green spaces, and activities to generate creativity through design and art.

That philosophy was carried over to Tokyo Midtown Hibiya (opened in Yurakucho, Chiyoda-ku, in 2018), where Mitsui Fudosan has been promoting neighborhood creation that harnesses the unique traits of Hibiya.

Tokyo Midtown Yaesu, which is the third facility in the Tokyo Midtown brand, has assumed the brand which was built up by Tokyo Midtown (Roppongi) and Tokyo Midtown Hibiya, and aims to be a neighborhood unique to Yaesu where Japan’s dreams come together and develop into the world’s dreams while promoting shared values.

“Mitsui Fudosan 9BOX Infection Control Measure Standards”

The Mitsui Fudosan Group has so far carried out thorough measures against COVID-19 according to each facility. However, the Group considered the necessity for easily understood infection prevention measures based on medical and engineering knowledge so that its facilities could be used with peace of mind even if a new variant were to spread in the future, and formulated the “Mitsui Fudosan 9BOX Infection Control Measure Standards” to be shared across the Group. The Group has developed diverse facilities such as office buildings, retail properties, hotels, resorts, logistics centers, and homes. By presenting measures that are easy to share not only within the Group but with all of society, it hopes to help solve society-wide issues.
Mitsui Fudosan will continue working to achieve a sustainable society through safe and secure neighborhood creation.

Under its "Colorful Work Project" slogan, Mitsui Fudosan is promoting a series of strategies to allow each individual employee to adopt a workstyle that best suits their needs. Through this approach, Mitsui Fudosan aims to pioneer new workstyles that allow users of Mitsui Office to achieve an optimal work-life balance.

Mitsui Fudosan Group’s Contribution to SDGs

By further accelerating its ESG management, the Group will realize Society 5.0, which the Japanese government has been advocating, and contribute significantly to achieving the SDGs. Additionally, the Group formulated the following Group guidelines related to “Realize a Decarbonized Society” and “Diversity & Inclusion Promotion” in November 2021.
