Learned few words.
OHAIO GOZAIMASU - Correct, right? U is almost silent, right?
KONICHIWA - A normal greeting.
ITADIKIMASU - You say this before eating, but sounds funny and might bring embarrassment IMO.
Need to learn phrases.
How do you say. "How are you", beside those greetings.
Japanese alphabet is funny. Instead of having vowels and consonants, each consonants has its own vowel version
