Grand Opening on April 21! New Yokohama Experiences Fusing Old and New

A New Landmark Hotel That Inherits the Legacy of Yokohama—OMO7 Yokohama by Hoshino Resorts
OMO7 Yokohama by Hoshino Resorts is centered around the concept of “Groove to Yokohama-ism.” Scheduled to open on April 21, 2026, the hotel is a legacy property that repurposes the former Yokohama City Hall administrative building, a modernist masterpiece designed by architect Togo Murano. Guests can immerse themselves in the nostalgic atmosphere of the era, from original exteriors decorated with dark brown tiles to guest rooms that reflect the rich tones of the former city hall interiors. The hotel offers a vibrant base for experiencing Yokohama like a local, carrying forward the legacy of the Kannai district while contributing to the area’s continued evolution.

Birth of One of the Largest Environmentally Friendly Offices in Yokohama’s Kannai Area

The office area on the 12th to 33rd floors of the Tower will host tenants from a wide variety of industries, including DeNA Co., Ltd., a consortium company. The 11th floor will be home to the innovation center “co-ba yokohama kannai,” which will host events for workers, provide shared spaces for office tenant use, and showcase areas where companies can exhibit their products. These facilities aim to establish an environment that generates new innovations through interactions among major corporations, startups, and research institutions such as universities.

Each office floor is approximately 22,604–24,756 ft² (approx. 2,100–2,300 m²) and features a column-free space with ceilings approximately 9 ft (2,800 mm) high, which can flexibly accommodate use by multiple departments on a single floor, as well as future layout modifications. In addition to the Tower’s excellent accessibility directly in front of the South Exit of JR Kannai Station, views of Yokohama Port, Yokohama Park, and Yokohama Stadium, along with Mt. Fuji on clear days, will boost workplace satisfaction among office workers.

From an environmental perspective, the facility incorporates a variety of environmentally friendly systems, including Low-E double-glazed glass (*1), high-efficiency individual air conditioning systems, and an external air processing system that reuses heat, to provide both comfort and energy efficiency. These initiatives have obtained CASBEE Smart Wellness Office S Rank (*2) and ZEB Oriented (*3) certifications for the building’s environmental performance. The Tower achieves a comfortable indoor environment year-round while minimizing energy waste.

• 1 Low-E double-glazed glass: Glass that maintains indoor comfort through a special metallic coating that blocks external heat and cold.
• 2 CASBEE Smart Wellness Office: A system that assesses the health and comfort of individuals working in buildings. It scores overall factors related to worker health and productivity, such as warmth, air quality, lighting, sound environment, relaxation areas, promotion of physical activity, safety, IT infrastructure, and operational management. S Rank is the highest rating in this system.
• 3 ZEB Oriented: A certification granted to buildings that achieve a primary energy consumption reduction of 40% or more compared to government standards, along with incorporating one or more energy-saving technologies that have yet to be evaluated, such as CO2-controlled ventilation and advanced air conditioning controls.

Birth of One of Yokohama’s Largest New Industry Creation Centers—Mitsui Link Lab Yokohama Kannai

On the 6th floor of the Tower, Mitsui Fudosan and STELLAR SCIENCE FOUNDATION (hereafter, “SS-F”) will open one of Yokohama’s largest new industry creation centers.

Within the facility, Mitsui Fudosan has decided on the name Mitsui Link Lab Yokohama Kannai for its first rental lab and office in Yokohama. In addition, next-generation research facilities unique to SS-F will also be developed. The two entities will work together to create an urban-type innovation hub combining wet labs that support cutting-edge research with diverse interaction functions.

In addition to advanced wet labs, the new industry creation center will also provide facilities such as meeting rooms, event spaces, and a networking lounge to promote interaction between companies and researchers. Mitsui Link Lab will provide necessary functions to generate innovation, from research activities to collaboration and information dissemination.

Mitsui Fudosan has been promoting the formation of a researchers’ community at facilities such as Mitsui Link Lab Shinkiba and Mitsui Link Lab Kashiwa-no-ha. Mitsui Link Lab Yokohama Kannai marks the series’ expansion into a new area. The existing facilities include wet labs, lounges, and other features that promote the gathering of researchers. This new facility will also support the creation of innovation that spreads from Yokohama to the world.

■ Area Management Initiatives

BASEGATE YOKOHAMA KANNAI will actively implement area management to create vibrancy that the local community can enjoy. Primary initiatives include the development of plazas, Legacy Walk, and a Visitor Front. Furthermore, The Green Slow Mobility system will also operate to enhance mobility throughout the district.

Plazas and Signage

Three plazas—Central Plaza, Kusunoki Square, and Stadium Side Square—will open within the area as part of efforts to generate vibrancy. These plazas will hold events, including community collaboration and seasonal events, bringing new excitement to the station front. The large signage facing Central Plaza will provide a wide array of content, including facility information for BASEGATE YOKOHAMA KANNAI and the surrounding area. The facilities will provide convenience and a touch of color to the lives of community residents, serving as a local media outlet that curates and communicates the appeal of the district from the gateway of the Kannai area.

Furthermore, indoor and outdoor signage will feature two dynamic videos by the artist Kenta Cobayashi on the themes of hare (the extraordinary) and ke (the ordinary) in Kannai. Created using cutting-edge, experimental digital painting, the videos highlight the appeal of Kannai while also incorporating AI technology, creating mystic visual effects that evoke a sensation of floating and flying around the city.

Comment from the artist Kenta Cobayashi

I took bird’s-eye shots from high above for hare, which is based on the nighttime scenery of Kannai, including areas such as Yokohama Stadium and Noge. The piece especially focuses on the “Yokohama Blue” theme color of Yokohama Stadium. It is used as the main color for the brushstrokes to create visuals that capture the nighttime appeal, which is a dramatic contrast from the daytime. On the other hand, ke uses historical Kannai buildings as its primary motif and expresses the dignified atmosphere of the brick buildings of Kannai as a port town since the opening of the port, through brushstrokes that stretch the colors of photos. This piece also communicates how enjoyable the city is to walk around, as I used the technique of filming while actually strolling through the area.

Legacy Walk

The urban development philosophy of BASEGATE YOKOHAMA KANNAI is Legacy, Revitalization, and Creation. Born on the former site of the seventh Yokohama City Hall, this location has been the site of not only the seventh City Hall but also successive Yokohama City Halls throughout history. The location was also home to a fish market, which generated vibrancy in the city.

An exhibition space that introduces various memories of the district is featured along Legacy Walk. The pathway was created in the hope that it will connect the memories of the development of Yokohama Kannai up to this point and pass them on to the future growth of the area.

The exhibition space features part of a Taizan tile relief art piece titled “Sea, Waves, and Ships,” which was relocated and preserved from its original location in the former city council building. Furthermore, the ceiling relief from the former City Council Chamber has been reproduced on a smaller scale through 3D scanning technology. Visitors will also be able to view exhibitions related to the area’s history.
