If you have an iphone/ipad/ipod, check out either Kotoba or Japanese, two wonderful apps that helped me tremendously when I was in Japan. Also if you use Mozilla Firefox, get the Rikaichan add on. When activated, all you have to do is highlight any Japanese word and it comes up with a box that shows it's meaning and other helpful info. Hope that helps!

Yes くるま - a car あした - tomorrow おすし - sushi たべる - to eat わからない - I don't understand (I guess) lol I'm a begginer too. @_@ You can use online dictionary, if you don't have "book". http://tangorin.com/
