In the Japanese language there is formal and informal speech. Formal speech is used when speaking to someone who is one’s superior (i.e. teacher, boss, elder) and informal speech is used when speaking to someone who is an equal or inferior (i.e. friend, employee, child).
If you are expressing gratitude to someone who is your superior, “Dōmo Arigatō Gozaimashita” would be used.
If you are expressing gratitude to someone who is your inferior, you would use “Dōmō Arigatō” or simply, “Dōmō.”
These phrases would be the English equivalent to “Thank you very much,” “Thank you” and “Thanks.”
Dōmō Arigatō Gozaimashita for stopping by and reading this blog. See you on the mat!
