Ishin-denshin & Shuhari

I also interested in Japanese Language, they have few sound pronounciation, so there will be a lot of words that will be pronounced the same ways. However the interesting part is how they use intonation to differentiate the meaning.

Since the Japanese strive for harmony and are group dependent, they rely on facial expression,
tone of voice and posture to tell them what someone feels. They often trust non-verbal messages more than the
spoken word as words can have several meanings.

"Ishin-denshin (Kanji: 以心伝心) "is a Japanese concept of communication through unspoken implication.The term is often used to describe nonverbal, mutual understanding that takes place between two people and is supposedly unique to the Japanese.[1]

This tendency can be repellent to Japanese workers, who practice "ishin-denshin" -- communication by the heart.This term is important in learning a technique from others. Most technique must be learn by watch and sense by own body.However this process sometime takes time and in business scenes it will interrupt with the standardizing of the work process.

Another term that i like is Shuhari (Kanji: 守破離)
Shuhari is a Japanese martial art concept, and describes the stages of learning to mastery.
It is sometimes applied to other Japanese disciplines.

Shuhari roughly translates to "first learn, then detach, and finally transcend."
Shu (守) "protect", "obey" — traditional wisdom — learning fundamentals, techniques, heuristics, proverbs
Ha (破) "detach", "digress" — breaking with tradition — detachment from the illusions of self
Ri (離) "leave", "separate" — transcendence — there are no techniques or proverbs, all moves are natural,
becoming one with spirit alone without clinging to forms; transcending the physical
