Overview

Nankinken Foods (株式会社南京軒食品, Nankinken Shokuhin) is a Japanese noodle manufacturer headquartered in Toda, Saitama Prefecture. It traces its origins to 1914, when it was founded as Nankin Seimenjo (南京製麺所), a limited partnership. The current corporate entity was established in March 1973, inheriting the business of Nankin Seimenjo. The company specializes in the manufacture and sale of various Chinese-style noodles (中華麺), tailoring its products to the preferences of ramen shops. Its product lineup exceeds 300 items. It built its sales base primarily in the Greater Tokyo metropolitan area, and for the fiscal year ending February 2010 it recorded sales of approximately 1.248 billion yen. A subsidiary, Marunan Food, operates the ramen shop chain Ganso Sapporo-ya. However, because about 90% of its customers were individually owned ramen shops and Chinese restaurants, the company was severely affected by the wave of closures, business cessations, and bankruptcies among such establishments. Sales fell below 1 billion yen in the fiscal year ending February 2015, and from the fiscal year ending February 2017 through the fiscal year ending February 2019, the company posted three consecutive years of declining revenue and net losses. In the fiscal year ending August 2020, sales plunged to approximately 164 million yen due to the impact of the COVID-19 pandemic. As a result, on April 21, 2021, Nankinken Foods, together with Marunan Food, filed for civil rehabilitation proceedings (民事再生法) with the Tokyo District Court, and received a supervision order the same day. Total liabilities were approximately 650 million yen. Yamato Foods, headquartered in Utsunomiya, Tochigi Prefecture, was selected as the civil rehabilitation sponsor. In July 2021, Yamato Foods established new companies—Nankinken Foods (new) and Marunan Food (new)—to succeed the businesses of the two former companies. On August 1, 2021, the two new companies took over the businesses from the old Nankinken Foods and old Marunan Food. The new company's headquarters is located in Toda, Saitama Prefecture, where the factory is situated. The old Nankinken Foods and old Marunan Food changed their trade names to NKK Co., Ltd. and MNF Co., Ltd., respectively, on August 1, 2021, and continue to proceed with the civil rehabilitation proceedings. The brand remains active under the new entity backed by Yamato Foods.

History

Nankinken Foods traces its origins to 1914, when it was founded as Nankin Seimenjo (南京製麺所), a limited partnership (合資会社). The current corporate entity, Nankinken Foods Co., Ltd., was established in March 1973, succeeding the business of Nankin Seimenjo. The company manufactured and sold various Chinese-style noodles, tailoring its products to the preferences of ramen shops, and its product lineup grew to exceed 300 items. It built its sales base primarily in the Greater Tokyo metropolitan area. For the fiscal year ending February 2010, sales were approximately 1.248 billion yen. Its subsidiary Marunan Food operated the ramen shop chain Ganso Sapporo-ya. However, because about 90% of its customers were individually owned ramen shops and Chinese restaurants, the company was hit hard by the successive closures, business cessations, and bankruptcies of such establishments. Sales fell below 1 billion yen in the fiscal year ending February 2015, and from the fiscal year ending February 2017 through the fiscal year ending February 2019, the company recorded three consecutive years of declining revenue and net losses. In the fiscal year ending August 2020, sales dropped to approximately 164 million yen due to the impact of the novel coronavirus. Consequently, on April 21, 2021, Nankinken Foods, together with Marunan Food, filed for civil rehabilitation proceedings under the Civil Rehabilitation Act with the Tokyo District Court, and received a supervision order the same day. Total liabilities were approximately 650 million yen. Yamato Foods, headquartered in Utsunomiya, Tochigi Prefecture, was selected as the civil rehabilitation sponsor. In July 2021, Yamato Foods established two new companies—Nankinken Foods Co., Ltd. (new) and Marunan Food Co., Ltd. (new)—to succeed the businesses of the two former companies. On August 1, 2021, the two new companies took over the businesses from the old Nankinken Foods and old Marunan Food. The new company's headquarters is located in Toda, Saitama Prefecture, where the factory is situated. The old Nankinken Foods and old Marunan Food changed their trade names to NKK Co., Ltd. and MNF Co., Ltd., respectively, on August 1, 2021, and continue to proceed with the civil rehabilitation proceedings.
