Overview
JC Service Co., Ltd. (株式会社JCサービス) was a Japanese company engaged in the design, development, installation, and maintenance of renewable energy power generation systems, primarily solar power. It was founded in March 2003 by Masami Nakakubo, a former Hyogo Prefectural Government employee. The company was headquartered in Hyogo Prefecture and operated mainly in the Japanese market, later expanding into domestic biomass power and overseas hydropower projects. At its peak, JC Service reported sales of 6.216 billion yen for the fiscal year ending November 2016. However, sales declined to 5.767 billion yen for the fiscal year ending November 2017 as project numbers fell. The company then shifted focus to biomass and overseas hydropower, but delays in land-use rights acquisition and the impact of the COVID-19 pandemic in 2020 worsened its business conditions. In March 2021, JC Service filed for civil rehabilitation (民事再生法) with the Tokyo District Court after its subsidiary Green Infrastructure Lending faced a bankruptcy petition from maneo Market. The court initially issued a preservation order, but later decided on a supervised rehabilitation with a trustee, rejecting the management's request for debtor-in-possession proceedings. The rehabilitation proceedings were discontinued on September 9, 2021, and bankruptcy proceedings commenced on October 9, 2021, with total liabilities of 15.342854 billion yen. Founder Masami Nakakubo himself received a bankruptcy commencement decision on July 28, 2021. The company is now defunct.
History
JC Service Co., Ltd. was established in March 2003 by Masami Nakakubo, who had previously worked as a Hyogo Prefectural Government employee. The company focused on the design, development, installation, equipment sales, and maintenance of renewable energy power generation systems, including solar power. For the fiscal year ending November 2016, JC Service recorded sales of 6.216 billion yen. However, by the fiscal year ending November 2017, sales had fallen to 5.767 billion yen due to a decrease in projects, signaling that its expansion strategy was losing momentum. The company subsequently shifted its focus to domestic biomass power generation and overseas hydropower projects. Nevertheless, significant delays occurred in procedures for acquiring land-use rights, and the COVID-19 pandemic in 2020 further delayed development processes, worsening business conditions. In a further blow, its subsidiary Green Infrastructure Lending received a bankruptcy petition from maneo Market on March 8, 2021, and on April 9, 2021, the Tokyo District Court granted a third-party bankruptcy petition filed by maneo Market, initiating bankruptcy proceedings for Green Infrastructure Lending. JC Service, facing the possibility of a third-party bankruptcy, filed for civil rehabilitation under the Civil Rehabilitation Act with the Tokyo District Court on March 24, 2021, and received a preservation order on March 31, 2021. JC Service denied allegations from creditors of fraudulent conduct with Green Infrastructure Lending. President Nakakubo sought a debtor-in-possession (DIP) type civil rehabilitation and solicited opinions from creditors. However, his request was not granted; on May 27, 2021, the Tokyo District Court decided to commence a supervised civil rehabilitation with a trustee who had stronger authority than management. Nakakubo himself received a bankruptcy commencement decision from the Tokyo District Court on July 28, 2021. JC Service continued operations under the trustee, but with no new projects and considering business costs, the trustee determined that there was no need to continue the business and that transitioning to bankruptcy proceedings was appropriate. JC Service received a decision to discontinue the civil rehabilitation proceedings on September 9, 2021, and a bankruptcy commencement decision on October 9, 2021. Total liabilities amounted to 15.342854 billion yen. An affiliated company, Biomass Project No. 1 LLC, was also petitioned for bankruptcy by JC Service's bankruptcy trustee and received a bankruptcy commencement decision from the Tokyo District Court on April 13, 2022. A separate attorney was appointed as the bankruptcy trustee for Biomass Project No. 1 LLC. Former subsidiaries included Green Infrastructure Lending, which received a bankruptcy commencement decision on April 9, 2021, and JC Securities, which received a bankruptcy commencement decision on September 1, 2021.
