I know:
hi (kunichiwa, but who doesn't know that)
goodbye (Sianara)
Dammit (Bleach in Japanese. Ca-so)
Strawberry (Ichigo)
Heart (Kokoro)
Thank you (Arigato)
Sorry (Ka-mi-no-sai)
Your welcome (can't remember it)
Peach (Momo)
I know more worthless words, but I don't think you care...
Yeep, sorry to nitpick but some of this is wrong and it would be bad for a beginner to get confused by wrong things.
'Kami no sai' would mean the 'age of paper' in Japanese ... or something like that. Sorry is usually 'sumimasen', 'sitsurei-shimasu' or 'ojamashimasu' depending on the situation.
For 'hi', you say 'ohayou gozaimasu' or 'ohayou' in the morning. 'konnichiha' in the daytime and 'konbanha' at night.
'Goodbye' is 'sayonara' in formal situations. When your friends are leaving your house or something like that, you'd say 'ja nee'.
'You're welcome' is 'dou ita simashite'
I don't know what you are going for with 'caso'. There is a similar word, but considering what it actually means it can't be written on these forums. The word a Japanses person would use in the same situations to where we would use 'damn' is 'shimatta'.
Again, sorry to nitpick. In apology, here are some phrases I like:
'Tonde mo nai' = 'of course not'
'kankei nai' = 'none of your bussiness'
'bikkuri shita' = 'I'm surprised' or 'you startled me' (It's fun to say)
Is there anything in particular you want to know how to say?
