It is said our national language was borne 5,000 years ago.
I would like to assimilate our ancient wisdom by it.
During Johmon period (14,000-1,000b.c.), no weapon to people remains were found.
Johmon people seems to have been very happy. A man worked only 4 hours to feed his family. As far as they were easy to get food, no need to struggle.
If you study Japanese language, especially ancient Japanese, Yamato kotoba, you can learn real Japan culture.
For example, こ means;
1.small(with things)
2.very few
3.infant young
4. about (with counting noun)
5.little motion(with body part)
6.small(with adverb)
7.disrespect(with noun)

Hiragana is very simple but very deep.
