Subaru is the name of a star cluster in the Taurus constellation. Six of its stars are visible to the naked eye, but about 250 bluish stars can be seen if one uses a telescope.

In the West the cluster is called Pleiades, in China, Mao, and in Japan, Subaru ("to govern" or gather together"). In Japan, it also goes by the name Mutsuraboshi ("Six Stars"), under which title it appears frequently in very old Japanese documents such as Kojiki and Manyosyu and literature such as Makura-no-soshi. Clearly, this is one of the clusters much loved by the Japanese from ancient times. Interestingly enough, FHI was created by the merger of six companies, so you can see what a truly evocative name Subaru is.
