The word “don don” is another word that describes state or conditions in Japanese, but it is such a super versatile word that we use on many occasions. So, I figured why not cover this in today’s lesson. Once you are immersed in Japanese language, you will hear this word sooner or later. 
Don Don (ใฉใใฉใ,ใใณใใณ) – loud noise (such as, knocking the door, beating a drum, and pounding the table loudly) bouncy noise, steadily, fast, away, rapidly, gradually, go ahead, etc.
