To whom it may concern

TOSEI CORPORATION (Head Office: Minato-ku, Tokyo; President and CEO: Seiichiro Yamaguchi; Securities Code:8923) is pleased to announce that, as of today, we have commenced operations for "TREC No. 13 Kunitachi Apartment Fund"(the "Fund"), which began its fundraising on January 19, 2026.
Only investors that are residents of Japan are permitted to invest in the Fund and use our services related to investing in the Fund. Investors that are non-residents of Japan are not permitted to invest in the Fund or otherwise receive our services, so we cannot accept investment requests from any investors that are non-residents of Japan.

The fund is an "income gain-oriented" fund that invests in a single income-generating apartment building located in Kunitachi, Tokyo, and aims to ensure stable income. As a result of the large number of investment applications received, the total amount of 192 million yen has been subscribed to the fund, and it has begun operations today.
We will conduct leasing activities for the vacant units, aiming to achieve full occupancy at the earliest possible date. We will strive to improve cash flow by revising rents to appropriate levels at the time of contract renewal. Through these initiatives, we seek to improve the property value, maximize rental income and gains on sales during the investment period, and manage the fund more profitably for investors.
To meet the expectations of more investors, we will continue to conduct appropriate fund management, provide attractive investment opportunities, and enhance our services.
