The brand is Hitachi Japan

Hitachi, as a global leader in the social innovation business, carries out business in the fields of power, energy, industry, distribution, water, urban construction, finance, public ****, healthcare and other fields to provide high-quality solutions through co-creating with customers. China is one of the most important markets for Hitachi. As of the end of FY2015, Hitachi Group has 180 group companies in China, with about 47,800 regular employees, and sales in the Chinese market amounted to 1,055.5 billion yen, accounting for about 10% of Hitachi Group's total global sales.

The main ones involving ordinary people are air conditioners and other home appliances. But now China's technology and Japan's is almost the same, so from the support of national industry out, do not recommend buying.
