What do the six hearts of Subaru logo stand for?

Mr. Kita, the first president of Fuji Heavy Industries (FHI), gave this car a Japanese name-Subaru.

Subaru is a cluster of Taurus. Among its stars, 6 stars can be seen with naked eyes, but about 250 other light blue stars can only be seen with telescopes.

In the west, this cluster is called the Pleiades; ; In China, it is called the Pleiades (Mao); It is called Subaru in Japan (meaning "ruling" or "gathering"). In Japan, it also has a name called Mutsuraboshi (meaning "six stars"), which appears more frequently in some occasions, such as in some Japanese official documents long ago, such as Kojiki, Manyosyu and Makura-no-soshi. Obviously, this is one of the clusters that the Japanese have loved since ancient times. More interestingly, Fuji Heavy Industries was formed by the merger of six companies, which shows how attractive Subaru is.
