You can find several sites with useful phrases for travelers. However, in Japan you might easily find yourself unable to find the toilet, or to understand a coin's value (bills also use Western numbering, but coins only have kanji!) So, here's a list of (what I hope should be) most of the essentials :)
One useful tip is to always print out the kanji of everywhere you want to go, including station names, and keep it with you! Or, if you can't print it out, copy/paste it (or keep a screenshot) on your phone.

Still alive and breathing? :)
If you still want to study more, I suggest that you learn the Katakana. 95% of what's written in Katakana is actually English! Find a nice page with mnemonics and prepare your flashcards!
