Hitachi is currently one of the eight major motor manufacturers in Japan, along with Panasonic, Sony, Mitsubishi and other companies. In 2018, the company ranked 79th on the Fortune Global 500 list. Hitachi's two business segments are Home Appliances and Professional Machinery, targeting the consumer market and the professional market, respectively.
 
Hitachi's home appliance business started late in Chinese mainland, and it is difficult to compare with brands such as Panasonic in the traditional home appliance market, so the company has invested more in emerging markets. Today, Hitachi Home Appliances has gained a good popularity and reputation in the Chinese market with a series of high-quality products with Meijian home appliances and projectors as the core.
 
Hitachi currently has three beauty instruments on sale, the models are CM-N50000, CM-N48000, CM-N40000, these three beauty instruments take the import and export function as the core, and rarely mention the concepts of ion, radio frequency, and current in the publicity, and the functions are more practical. All three devices use the same design language, with the main color being white. The fuselage carries two guide heads. The main head is made of titanium, which is safe and not easy to cause allergization in contact with the skin. Through changes in the frequency of heating and vibration, the dominant head provides a secondary cleanse to the skin and promotes the absorption of lotions and masks. The guide on the back is a low-temperature guide head, which can be pre-cooled and touched to the skin, which can cause the skin to shrink when it is cold.
 
Among the three products, CM-N40000 is priced at more than 1,000 yuan, which is the most cost-effective. The CM-N48000 is sold for hundreds of yuan higher, and the difference with CM-N40000 is only in the panel color. The latest upgraded version of CM-N50000 is priced at about 2000 yuan, and the guide head has a spot detection function, which can adjust the vibration intensity according to the depth of the color of the facial spots, but this function is relatively weak in actual use, so it is recommended that consumers buy CM-N40000 and CM-N48000.
