Overview

ReNK CHANNEL Co., Ltd. (リンクチャネル株式会社) is a Japanese information technology company headquartered in Shibata, Niigata Prefecture. It operates as a wholly owned subsidiary of Hard Off Corporation, a major retailer of second-hand goods in Japan. The company was originally established on July 1, 1997, under the name Infonorth Co., Ltd. (インフォノース株式会社), based in Tokamachi, Niigata. For many years, Infonorth provided contracted POS system development services, primarily for Hard Off Corporation. On February 12, 2020, Hard Off Corporation announced its intention to acquire Infonorth as a wholly owned subsidiary, effective April 1, 2020, in order to bring POS system development in-house. On that date, Infonorth became a wholly owned subsidiary of Hard Off Corporation, changed its corporate name to ReNK CHANNEL Co., Ltd., and relocated its headquarters from Tokamachi to Shibata, aligning with Hard Off Corporation's headquarters location. The name "ReNK CHANNEL" reflects the company's role in integrating Hard Off's physical stores with its online mall, Hard Off Net Mall, creating a unified retail channel. ReNK CHANNEL's core business is software development related to POS systems, as well as systems integration. It also engages in the sale of Seiko Epson products. The company maintains several offices in Niigata Prefecture, including its headquarters in Shibata, a development center in Tokamachi (the former head office), a customer service center in Nagaoka, and the "Hard Off Mirai Lab" in Niigata City. It also has a Tokyo office in Minato, Tokyo. As a subsidiary of Hard Off Corporation, ReNK CHANNEL supports the parent company's retail operations and technological infrastructure.

History

ReNK CHANNEL Co., Ltd. was originally founded on July 1, 1997, as Infonorth Co., Ltd. (インフォノース株式会社), headquartered in Tokamachi, Niigata Prefecture, Japan. The company specialized in software development related to POS systems and systems integration, and it also sold Seiko Epson products. Over the years, Infonorth became a key external contractor for Hard Off Corporation, a major Japanese retailer of second-hand goods, providing POS system development services. On February 12, 2020, Hard Off Corporation announced its decision to acquire Infonorth as a wholly owned subsidiary, aiming to internalize POS system development. The acquisition was completed on April 1, 2020, through a share transfer. On the same date, Infonorth changed its corporate name to ReNK CHANNEL Co., Ltd. and relocated its headquarters from Tokamachi to Shibata, Niigata Prefecture, to share the same address as Hard Off Corporation's headquarters. The new name "ReNK CHANNEL" was chosen to represent the integration of physical stores and the Hard Off Net Mall online channel, a concept referred to as the "Re"NK CHANNEL. Following the acquisition, ReNK CHANNEL continued its core business of POS system software development and systems integration, while also supporting Hard Off Corporation's retail technology needs. The company maintains several offices in Niigata Prefecture: the headquarters in Shibata, the Tokamachi Development Center (the former head office), the Nagaoka CS Center, and the Hard Off Mirai Lab in Niigata City. It also operates a Tokyo Office in Minato, Tokyo. As of the available information, ReNK CHANNEL remains an active wholly owned subsidiary of Hard Off Corporation.
