Interestingly, the word arigato has Buddhist and classical roots. It comes from the old Japanese phrase:
“arigatashi” (有り難し)
Which means “rare” or “difficult to exist.”
Originally, it was used to describe something that was so precious or rare that it was hard to come by—like a once-in-a-lifetime moment or a deeply meaningful favor. Over time, that evolved into arigato, a way to acknowledge and appreciate kindness or effort, even in small things.
So when you say “arigato,” you’re not just saying “thanks”—you’re recognizing that someone went out of their way for you. It’s subtle, but meaningful.
