On September 14, 2023, the company changed its name to “NIMASO JAPAN K.K.” to unify its corporate name with its brand name. The corporate registration number is “2010501040822,” which can also be verified via the Ministry of Economy, Trade and Industry’s gBizINFO.
Ms.GadgetsWhy did it change from Benisong Co., Ltd. to NIMASO JAPAN?
Mr.GadgetsAccording to the company’s press release, the purpose was to achieve consistency between their business activities and corporate philosophy. It is believed that as the “NIMASO” brand name gained sufficient recognition, they adopted the brand name for the company name as well.
Although the Japanese subsidiary is relatively small, with 4 full-time employees and 19 part-time staff (as of September 2023), product development and manufacturing are said to be conducted in collaboration with affiliated companies in China. A branch office was also established in Shenzhen, China, in 2017, and the business is operated through a structure spanning both Japan and China.
Their sales channels are extensive; in addition to e-commerce sites such as Amazon, Rakuten Ichiba, Yahoo! Shopping, and Qoo10, they also sell directly via their official website and are carried by major electronics retailers like Yamada Denki, Yodobashi Camera, and Bic Camera.

However, please check, as the warranty period varies by product.
