Simply say it after someone does something nice for you. You can add a small bow to make it more sincere. The bow doesn't need to be deep. A simple nod of the head while speaking works wonders. If you want to be extra polite, add doumo at the beginning. This makes it doumo arigatou gozaimasu. It is like saying 'thank you very much indeed.'

Use it at a convenience store when you get your change. Use it at a restaurant when the waiter brings your food. It is perfect for the office when a colleague helps you. If a stranger gives you directions, this is the phrase to use. It works for people you don't know well or those above you. It keeps your social interactions smooth and respectful. Think of it as your 'polite shield' in daily life.

Don't use this with your best friend or siblings. It sounds too stiff and formal for close relationships. In those cases, just a simple arigatou is much better. Also, be careful with the tense. If the favor happened in the past, use arigatou gozaimashita. Using the present tense for a past favor sounds a bit like you're still waiting for it! Finally, don't mumble it. A clear delivery shows true appreciation.

The phrase has its roots in Buddhist teachings. It originally described things that were 'rare' or 'miraculous.' Over time, it evolved into a way to thank others for their 'rare' kindness. Japanese culture places a massive emphasis on harmony and mutual debt. By saying this, you are acknowledging the effort someone made for you. It is more than just words; it is a social glue.

Arigatou is the casual version for friends. Doumo is a very short, slightly masculine way to say 'thanks.' Arigatou gozaimashita is the past tense for completed favors. In the Kansai region, you might hear ookini. Some young people use the slang azasu, but keep that for the gym! Stick to the full version until you are comfortable.
