Social Initiatives

NBF is engaged in initiatives for development of local communities as well as improving security and safety.

Initiatives for local Communities

As a part of local communities, NBF holds initiatives such as lunchtime concerts, seasonal events, water sprinkling programs for cooling down and local cleanup programs.

Due to the impact of the Covid-19, events are being cancelled and non-contact events are being held in FY2020. From next year onwards, we will continue to consider holding events while taking into account the status of the Covid-19 and other factors.

Increase of Comfort

In NBF's capital investment decision making process, the status of the building's compliance with the Barrier-Free Law, accessibility for people with disabilities, accessibility to public transportation around the property, etc. are mandatory items to be confirmed. These items are periodically confirmed through engineering reports and other documents obtained during the consideration stage and post-investment monitoring phases, and if there are issues or room for improvement, specific measures are discussed during the operation stage.

Through these inclusive efforts, we aim to provide a building that is comfortable for all office users.
