Last month my Japanese language school that I take classes at had a used book sale (though some were new from kinokuniya in NYC). All the books were a $1 and the few new ones were $2. There were also some free ones that had some extra wear. Most of the ones I got were children’s books since they are suited to my Japanese reading level. Thought I did get a fashion magazine and an exercise book that has some really good things in it. The exercise book is named Real Simple. Also I got a Hello Kitty little kids activity book that I love so much. It’s super simple but has fun games while learning a little bit of Japanese, plus it has stickers!
A real good one for practicing kanji and general reading is the となりのトトロbook. Since I’m familiar with the story it’s an easy read and great practice. Another one that is short and cute is くまのスリーピー. It’s about a bear who is sleepy and tries finding different beds of other animals but none work out except his own. It’s cute. I also picked up the manga Death Note which is good since all the kanji has furigana. I got many others but these are my favorites.
