Background of Sponsorship and Exhibition

The alternative investment service "ALTERNA" provided by the Company is backed by real assets such as large-scale urban real estate and logistics facilities. Real assets only function when they are connected to the people who live there and the community of the town. As a financial services provider dealing in real assets, the Company wishes to be continuously involved in activities that support local communities.

The Company's head office is located in Nihonbashi, Chuo-ku, and as a member of the Mitsui Group, we conduct our business rooted in the local community. In the Harumi area of Chuo-ku, new town development is progressing, and the "Harumi Pier Park Bon Odori Festival" is an event that is growing as a summer tradition in the area.

As a company that walks alongside the community, we have decided to sponsor and exhibit at this festival with the desire to deliver a fun summer moment to all visitors and to raise awareness of assets that support their lives.
