Discover the Excitement of Marunouchi During the Inaugural Summer Fest in 2026

The MARUNOUCHI SUMMER FEST, an initiative designed to bring together the community, businesses, public spaces, and individuals, is set to launch for the first time from July 24 to August 23, 2026, in the Marunouchi area. This unique cross-sector collaboration aims to offer diverse workshops and events that people of all ages can enjoy throughout the city.

This innovative festival, organized by a consortium led by the Otemachi-Marunouchi-Yurakucho District Development Council, Rigale Daimaru Area Management Association, Eco-Tsuzeria Association, and Mitsubishi Estate, will transform Marunouchi into a summer hub of joy. The festival's mission aligns with the evolving role of business districts, which are now not only places of work but vibrant spaces for community engagement and delightful experiences that enhance quality of life.

A City for Work and Play

As new work styles emerge, urban areas are increasingly called upon to fulfill complex roles in enhancing the quality of life through socializing, learning, and entertainment. The Marunouchi district is embracing this change, leveraging the interconnectedness of its companies, shops, public spaces, and citizens to improve the area's charm and the satisfaction and quality of life of its workers.

Traditionally, summer activities have included festival dances and water-splashing events, but the MARUNOUCHI SUMMER FEST aims to expand these offerings creatively. By promoting a variety of exciting initiatives throughout the entire city, the event aspires to become a new summer tradition in Marunouchi, inviting workers and their families to explore and engage in rich, enjoyable experiences right in their neighborhood.

By providing diverse activities that connect employees and families through everyday experiences, the festival aims to deepen the love for Marunouchi, leading to a sustainable enhancement of the city's value. High-profile corporate stakeholders, local authorities, and community organizations are collaborating to expand upon this vision effectively.
