About Ligare

OMY Area Management Association (Ligare) is a non-profit organization established in 2002 with the support of the district's landowner council to revitalize the Otemachi, Marunouchi, and Yurakucho (OMY) district. Ligare means "to connect" in Latin and is the nickname for the organization in the hope of connecting people to the community and to each other.

Traditionally, OMY had been a business district where people only worked during the weekdays and was empty at night and on weekends. In 1988, a council was established to bring together landowners in the district, and the creation of a new vision for the community began. Subsequently, in 1996, a round-table discussion group was set up with landowners and the government. And in 2000, city planning guidelines were formulated as a common vision for the public and private sectors. Since then, many buildings have been rebuilt or redeveloped based on the guidelines. At the same time, Ligare has promoted myriad activities in the intangible aspects of city planning, not only for redevelopment but also for the well-being and happiness of the people who visit and work there and for the further prosperity of corporate activities.

Otemachi, Marunouchi,
and Yurakucho
(OMY District)

Located between Tokyo Station and the Imperial Palace in the heart of Japan, it is the largest business center in Japan with an area spanning 120 hectares. It is a community comprising about 100 buildings, 5,000 offices, and a working population of about 350,000.

The OMY district used to have only office buildings, but since 2000, it has undergone a major transformation into a sophisticated urban center with retails stores, cafés, and restaurants lining the streets. It also features a cluster of Japan's top-ranked hotels and convention facilities, making it a lively scene even on weekends.
