Can you tell me please how can I know the correct words for it?
では、まいりましようぞ!
then, Mairimashi!

You said that まいりましようぞ! in Romaji is Mairimashi! I couldn't find a translation for it in the dictionary....

For any Japanese sentence how can I look up for words like these?
Sometimes I don't know how to form a word from the sentence..
