Circle of Collaboration

What Circle of Collaboration does

Circle of Collaboration (有限会社　協業の輪) is a privately held Japanese limited liability company (Yūgen gaisha) founded in 2018 and headquartered inside Office Toshikawa in Hikone City, Shiga Prefecture, in Japan's Kansai region. The company operates three documented business lines: real estate services, business consulting, and cancer patient support activities. The real estate and consulting functions constitute the commercial revenue base, structured as one-time real estate transactions and professional consulting engagements, while the cancer patient association activities — seminars, networking events, and gatherings centered on employment support for cancer patients — function as a community-facing social initiative with no disclosed monetization mechanism.

The company's primary persona segment is individuals affected by cancer who are seeking employment support, peer connection, and community resources, primarily within the Kansai region. Distribution is conducted entirely through direct community events and a Facebook page; there is no technology platform, mobile application, API, or third-party integration referenced in any source. All documented activity is anchored to a single individual (Iwaya), who serves as the primary contact via personal mobile phone and email, and the website is a static AmebaOwnd page with content dating from 2018-2019.

No revenue, headcount, pricing, customer count, funding, institutional investors, parent company, patents, certifications, or third-party partnerships are disclosed. The company's documented activity is concentrated in the founding period and the launch of the first cancer patient meeting in January 2019; no subsequent product launches, geographic expansion, capital raises, or growth milestones have been recorded in the input data.
