ROXX

ROXX, inc. (株式会社ROXX) is a Tokyo-based HR technology company that applies software to supply-demand mismatches in the Japanese labour market with the stated goal of raising incomes across Japan. Its current business line is Z Career (Zキャリア), which includes a job-change platform specialising in the recruitment of full-time employees without prior experience in the role, and recruitment-support tools including Z Career AI Interviewer (Zキャリア AI面接官), a service intended to make interviewing more efficient and less burdensome for employers.

The company frames its mission around demographic and labour-market conditions in Japan, citing figures that non-university graduates account for roughly 70% of the working population, non-regular employment for about 30%, and people earning under ¥4 million a year for about 53%. Its stated approach is to raise the incomes of people without academic or career credentials and connect them with employers.

As of the end of September 2025, ROXX had 380 employees (excluding contractors and those on leave) and share capital including capital reserve of ¥3,470,320 thousand. It is headquartered at Shinjuku Eastside Square, 6-27-30 Shinjuku, Shinjuku-ku, Tokyo. Leadership includes founder and Representative Director/CEO Taro Nakajima, COO and SVP of Business Daisuke Ueki, SVP of Corporate Hiroto Nishimura, CAO Toshiki Takase, CTO Kota Matsumoto, CFO George Yoshimoto, and executive officers Kazuhito Owa, Yuhei Kagi and Shun Fujimine, with outside directors Masanori Sugiyama and Hiroshi Fukudome and auditors Tsuyoshi Kabaya, Shigeru Omura and Miki Amemiya.

Founding story

Taro Nakajima, born in Tokyo in 1992, initially pursued a career as a hard-rock musician before founding ROXX in 2013 while enrolled at Aoyama Gakuin University; he left the university in 2015. The company was formally established on 1 November 2013.

Business model

ROXX operates HR-tech services under the Z Career brand: a job-change platform focused on placing candidates into full-time roles that do not require prior experience, and recruitment-support products such as Z Career AI Interviewer, which is sold to employers to reduce interview workload. The company holds Japanese licences for fee-charging employment placement (13-ユ-307543) and worker dispatch (派13-316322), and has separate contact channels for job seekers and for corporate clients, indicating a two-sided model serving both candidates and hiring companies.

Revenue is generated from employment-related services provided to companies, operating under paid employment placement and worker dispatch licences, alongside recruitment-support software services such as Z Career AI Interviewer offered to employers.

Traction

The company reported 380 employees as of the end of September 2025 and share capital including capital reserve of ¥3,470,320 thousand at the same date. Its earlier agent bank business grew revenue approximately sixfold over three years from December 2018 under its business lead. By November 2022 it had raised approximately ¥3,500 million in total funding, and it listed on the Tokyo Stock Exchange Growth Market in September 2024.
