RC Core Co., Ltd. (Headquarters: Shibuya-ku, Tokyo; Representative Director and President: Yasuhiro Sumatsuki; hereinafter "RC Core"), which operates the detached housing business under the concept of "BESS Homes for Enjoying Life More Than Just Living," has commenced a collaborative project with Asahi Kasei Real Estate Residence Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; Representative Director and President: Yasumichi Ichikawa; hereinafter "Asahi Kasei Real Estate Residence") to provide rental housing, including multi-unit dwellings. Image: "BESS Homes for Enjoying Life More Than Just Living" Rental Housing Collaborative Project In September 2025, BESS launched its first rental multi-unit housing. They began recruiting monitors for a terrace house type design of their "Wonder Device" detached series, and the first monitor contract was signed in March 2026. Furthermore, on October 14, 2025, they concluded a capital and business alliance agreement with Asahi Kasei Homes Co., Ltd. (hereinafter "Asahi Kasei Homes") (Note 1). Note 1: https://ssl4.eir-parts.net/doc/7837/tdnet/2697532/00.pdf Following the alliance, both companies have been discussing various collaborations, focusing on: ① Business collaboration leveraging the characteristics of both companies' products and customer bases. ② Joint research on living spaces and lifestyles. ③ Mutual complementation and joint development in technology. Within these discussions, they also explored collaboration in rental multi-unit housing, an area where Asahi Kasei Homes possesses extensive business know-how. The rental housing that BESS aims to provide, similar to its custom-built detached homes, embodies the concept of "Enjoying Life More Than Just Living." This means offering lifestyles not possible in typical rental housing, such as "using fire," "gardening," and "DIY." The goal is to create a community where "people gather and connect" due to shared preferences, realizing the unique BESS resident lifestyle in rental properties. This unique added value became clearer during the collaborative discussions. Therefore, they decided to collaborate with Asahi Kasei Real Estate Residence, which has long managed rental properties that cater to the diverse lifestyles of residents in Asahi Kasei Homes' "Heimel Maison" community rental housing. Asahi Kasei Real Estate Residence has expertise and a proven track record in rental management, making it capable of high-quality, stable operations, from implementing the BESS rental concept to tenant recruitment and daily management. In March of this year, the first monitor was selected. While a prototype planning and design with monitors was initially planned, with the knowledge and expertise of Asahi Kasei Real Estate Residence, they will establish a consistent approach from concept realization in actual buildings to tenant recruitment and building management. Along with promoting the first monitor project, they aim to provide new value-added rental housing by leveraging the strengths of both companies. 1.
