EGG — Marunouchi: a gathering fire in a coworking space

EGG is a business community in the Shin-Marunouchi Building for overseas companies entering Japan and Japanese companies going global, run alongside Mitsubishi Estate’s innovation community. MAWD refurbished and expanded it around five drivers: collaboration, community, conscious design, connection and customisation.

Five drivers

MAWD applied its research-based, experience-centred approach to understand EGG’s next generation of tenants, many of whom want to make a positive environmental and social impact.

That led to five drivers: collaboration, community, conscious design, connection and customisation.
