Renxa, with Support Track Record for 60,000 Individuals from 102 Countries, Announces Partnership with Infinistone, a Real Estate and Life Support Specialist for Foreign Nationals

Renxa Inc. (Headquarters: Toshima-ku, Tokyo; Representative Director: Koji Sakamoto; hereinafter "the Company") announces that it has entered into a business partnership with Infinistone Co., Ltd. (Headquarters: Toshima-ku, Tokyo; Representative Director: Unryu Fujisawa; hereinafter "Infinistone"), a company specializing in real estate services for foreign nationals.

Background and Objectives

According to the Immigration Services Agency's report "Number of Foreign Residents as of the End of 2025" (*), the number of foreign residents in Japan reached approximately 4.12 million by the end of 2025, marking the highest level on record—an increase of 356,418 (9.5%) from the previous year. While Japan continues to expand its acceptance of foreign nationals, many face challenges during relocation, such as language barriers, unfamiliarity with local living norms, and complicated utility registration procedures, making it difficult to smoothly start their lives in Japan.

In response to these challenges, Infinistone operates under the corporate mission of "realizing a society of coexistence and co-creation across nationalities," offering specialized real estate brokerage services for foreign nationals (under the brand "Bangaku Fudousan"), life support services, Japanese language education, and employment support. A key strength unique to Infinistone is that all staff members, including Representative Director Unryu Fujisawa, are former international students themselves, enabling them to deeply understand the confusion and difficulties foreigners face.

Meanwhile, since January 2024, the Company has provided a lifestyle support service for foreign nationals called "Lifestyle Advisor Global," assisting over 60,000 individuals from 102 countries with essential utility registrations. The service supports contracts for electricity, gas, water, and internet in 14 languages and emphasizes dialogue to clearly explain Japanese living rules and the reasoning behind various procedures, helping prevent misunderstandings and friction in daily life.

Infinistone, which supports housing acquisition and pre- and post-move-in life assistance, and the Company, which provides native-language support for setting up essential utilities, share a common mission of solving challenges faced by foreign talent. Recognizing the synergistic potential of combining their expertise, the two companies have decided to form this business partnership.

Expected Benefits

With this partnership, Infinistone’s comprehensive support system will now include the Company’s utility contract assistance, enabling tenants to complete both housing arrangements and essential utility setup through a single point of contact. The partnership also allows flexible support for customers without credit cards or those with special circumstances. For individuals who do not yet have a Japanese phone number, communication channels via WeChat and LINE are available, ensuring a smooth process from immediately after arrival in Japan.

For Infinistone, access to the Company’s 14 supported languages will allow service expansion to a more diverse, multinational clientele, broadening its customer base. For the Company, collaboration with Infinistone’s extensive network—including over 50 institutions in China and more than 30 educational institutions in Japan—offers significant potential for increased awareness among Chinese nationals. The partnership is expected to deepen cooperation with Chinese-focused real estate agencies, enhancing the Company’s role in supporting the integration of Chinese talent.

Future Outlook

Through this partnership, both companies aim to expand collaboration with organizations that host foreign talent—such as Japanese language schools, corporations, and local governments—and to roll out a nationwide, one-stop system for housing and essential utilities. Leveraging field-tested insights accumulated by both companies, they will continuously enhance services tailored to regional needs and implement initiatives to prevent issues during the initial settlement phase, ultimately fostering an environment where foreign talent can live and work sustainably in Japan over the long term. The Company will continue striving to become a bridge between foreign talent and Japanese society, working toward a multicultural, inclusive society where everyone can live with peace of mind.
