Distribution of the tenant sustainability guide

As part of our sustainability promotion initiative, we hand out a guide intended for tenants (office building version). This guide is drawn up to collaborate with tenants, describing specific cases of energy-saving activities.

Green lease

We created a template for the clauses of an environment-friendly green lease and promote its incorporation into a lease with a tenant.

Posting ESG Posters

We have produced a poster encouraging cooperation concerning energy savings, water savings, and recycling measures. We display this in the common areas of the properties we have been entrusted to manage.

Ensuring tenants’ safety and security

Expanded deployment of AEDs (automated external defibrillators)

Contribution to the region/local community

Increased convenience for local residents

For example, at Honmoku Front, we offered a space needed to install ports for Yokohama City’s “baybike” community bicycles and installed parcel lockers, thereby contributing to cutting CO2 emissions or enhancing local residents’ convenience.
