When did Kamon start ?

Kamon is used for family's mark to identify each other.It started heian-era(平安時代794 - 1185) Very old people such Japanese noble put kamon their many items.They put kamon mark on their car that works by cow first. I don't know truth,but it's said origin is Tomoe-mon.

Wow,that's powerful,simple mark.My favorite one.And real wheel kamon existed.It's called  源氏車 genji-kuruma "genji(源氏)" is Japanese old noble family's name.

Eight legs imagines 八正道(hatu-sho-do)(one of Buddhism's ideology).

Currency very old

Japanese old currency was made model of kamon,too. Okay,first is popular it.Do you know whose mon is this ?
 
This is 六文銭(roku-mon-sen).真田幸村(Yukimura Sanada)'s family symbol.He is so famous.He is taken as game or comic hero in Japan.

Japanese old currency must be pierced.I think this hall was strung by cord instead of wallet.

And let's see some arrangement pattern.'裏浪銭紋'(ura-nami-sen-mon) is mixed wave.And pierced too.(^^)

This pattern is '六ツ念銭紋'(mutu-nen-sen-mon).'念' means 'to pray silently'.These currency represent wish.

I don't know why currency was used as kamon design.They might be banker,generate currency,or rend money.

Arrangement for girls

I've seen it looks like this before and somewhere.Especially girls like it.

This base is 轡紋(kutuwa-mon).轡 means horse's bit.This mon made at Sengoku era.Pattern is pretty simple.

Currently,this mon becomes popular by comics title is 'Drifters'.轡紋 is the hero's family mon in this comics.The hero's name is 島津豊久(Toyohisa Shimazu).
