Overview
Mansyo (株式会社萬松, MANSHO CO., LTD) was a Japanese company engaged in the molding and processing of phenolic resin and plastic products, primarily supplying automotive manufacturers. It was founded in February 1958 as Mansyo Paint Shop (萬松塗料商店), initially selling paints, and was reorganized into a corporation in March 1960 as Mansyo Paint Co., Ltd. (萬松塗料株式会社). In December 1973 the company changed its trade name to Mansyo Co., Ltd. (株式会社萬松). Over the decades Mansyo expanded its manufacturing footprint, opening the Saitama Plant in February 1974 and the Kyushu Plant in July 1977, and establishing Mansyo Philippines, Inc. in October 1994. In February 2011 it set up MANSHO DE MEXICO, SA DE CV. At its peak, for the fiscal year ending April 2000, the company recorded sales of 5,124,370,000 yen. However, the Mexican subsidiary established in 2011 suffered major losses due to mold defects and coating defects caused by Mexico's particular climate. Financial support provided to the Mexican subsidiary worsened Mansyo's cash flow, and a decline in orders amid weak automaker sales compounded the problem. The company obtained a principal repayment moratorium from financial institutions and in January 2018 requested support from the Small and Medium Enterprise Revitalization Support Council. Sales for the fiscal year ending April 2019 fell to about 2,835,000,000 yen, and the COVID-19 pandemic in 2020 further reduced automaker production, causing March and April 2020 sales to drop 30% year on year. Unable to secure funds for settlement at the end of April 2020, Mansyo filed for bankruptcy with the Tokyo District Court on April 28, 2020, and received a bankruptcy commencement decision on April 30, 2020. Its Saitama and Kyushu operations continued under the bankruptcy trustee; the Kyushu Plant was transferred on July 1, 2020 to Oita Dry Lube Co., Ltd. (established June 11, 2020 by Toyo Dry Lube), and the Saitama Plant was transferred on July 31, 2020 to YSP Co., Ltd. (established by Saitama Spring). Mansyo's corporate legal personality was extinguished on May 17, 2021.
History
Mansyo was founded in February 1958 as Mansyo Paint Shop (萬松塗料商店). In March 1960 it was reorganized into a corporation under the name Mansyo Paint Co., Ltd. (萬松塗料株式会社). Initially the business centered on the sale of paints, but it later moved into the manufacture of plastic products for automotive manufacturers and expanded its business relationships with major automakers. In December 1973 the company changed its trade name to Mansyo Co., Ltd. (株式会社萬松). It opened the Saitama Plant in February 1974 and the Kyushu Plant in July 1977. In October 1994 it established Mansyo Philippines, Inc. (フィリピン萬松株式会社). In February 2011 it established MANSHO DE MEXICO, SA DE CV. At its peak, for the fiscal year ending April 2000, sales reached 5,124,370,000 yen. However, the Mexican subsidiary established in 2011 generated large losses due to mold defects and coating defects caused by Mexico's particular climate. The financial support Mansyo extended to the Mexican subsidiary worsened its cash flow, and a decline in orders following weak automaker sales added further pressure. Mansyo obtained a moratorium on principal repayment from financial institutions and in January 2018 requested support from the Small and Medium Enterprise Revitalization Support Council. Sales for the fiscal year ending April 2019 fell to about 2,835,000,000 yen. The COVID-19 pandemic that emerged in 2020 led automakers to cut production, and Mansyo's sales in March and April 2020 fell 30% year on year. With no prospect of securing settlement funds for the end of April 2020, Mansyo filed for bankruptcy with the Tokyo District Court on April 28, 2020, and received a bankruptcy commencement decision on April 30, 2020. The Saitama Plant (in Yorii, Saitama Prefecture) and the Kyushu Plant (in Nakatsu, Oita Prefecture) continued operations under the bankruptcy trustee. The Kyushu Plant was transferred on July 1, 2020 by the bankruptcy trustee to Oita Dry Lube Co., Ltd., which had been established on June 11, 2020 by Toyo Dry Lube. The Saitama Plant was transferred on July 31, 2020 by the bankruptcy trustee to YSP Co., Ltd., established by Saitama Spring. Mansyo's corporate legal personality was extinguished on May 17, 2021.
