Kagome crest

The Kagome crest or is a star-shaped emblem related to the kagome lattice design. The Kagome mon can be depicted as, either, a six-pointed star (a hexagram) and as an eight-pointed star (an octagram): 
Regardless of which one, both the six-pointed star and the eight-pointed star are also known as "kagome". It can be found in many of the oldest Shinto shrines, dating back to at least the 5th century BCE, and is present on almost all the stone lanterns approaching the Ise-jingu. Its presence in Shinto shrines is believed to ward-away evil. This symbol is also synonymous with the "Cintamani", a "wish-fulfilling stone"(a Mani Jewel), both being icons associated with the goddess, "Lakshmi/Kisshōten". 
In regards to heraldry, the Kagome crest is also often associated with the Hata clan.
To a Western audience the six-pointed version of the "Kagome" crest as religious symbol perhaps most closely resembles the Star of David, however, any direct connection between the two is unlikely. If a cultural connection involving the Kagome crest does exist, it is most likely related to the "satkona" of Hinduism.
