While in Japan , I filled 2 big notebooks with words. First I learned the words I needed to buy things and order at a restaurant. Then words needed to travel around on bus , train , and taxi. I always carried a small Japanese/English dictionary with me everywhere. I was lucky and found a Japanese friend who wanted to learn more English and he helped me learn Japanese. Kanji was the most difficult , so I learned the other two small alphabets first and only learned the kanji I needed to use everyday. I think I bought over 25 different Japanese books to study from. After 2 years of hard work , I think I was only on the level of a 7 year old Japanese child. It's a hard language for sure.
