HAPPO-EN re-opend from October 1st 2025.

As many of you might already know, aiming for the ZEB Oriented certification and for an improvement towards an eco-friendly environment.

The themes of this refurbishment are “Inheritance”, meaning not the creation of a new building, but the protection of what needs to be kept to create a building that can last longer than the previous one, and “construction”, creating a new value through the collaboration with artisans who create the Japanese beauty aesthetic, with the cultural assets of a Japanese Garden, connecting to the new generation.
