I especially like Japanese anime and manga. They are very colorfal and exciting. Many people all over the world love Japanese anime and manga. There are many kinds of anime and manga in the world, but I think Japanese anime and manga are special. There are three reasons. First, in Japan there are many anime and manga not only for children but also for adults. Second, their pictures are beautiful and delicate. Third, their stories are very interesting. For example, we can enjoy history, comedy, friendship, sportsmanship, battles, and so on. What kind of anime and manga do you like? I like Princess Mononoke the best. My younger sister Judy likes Spirited Away, and many poeple in the world love the Ghibri anime. I read Japanese manga every day when I was in the U.S. I like One Piece the best of all Japanese manga, so I choose Kumamoto to study Japanese. I heard that statues of One Piece characters such as Luffy are standing in Kumamoto. I want to visit all the statues during my stay in Kumamoto. Now I see many anime and read many manga in Japanese every day, so I can learn Japanese culture from them. Thanks to reading Japanese manga, I become able to speak Japanese little by little. And I like Japanese food, too. Japanese food is usually healthy and delicious, so many people in the U.S. eat it to lose weight. Sushi, soba, udon, and tofu are very popular there.

About a month ago, we had natto at school lunch. First I couldn't eat it, but 3 many of my Japanese freinds looked happy when they ate it, so I tried it. The smell was not good, but the taste was better than I thought. Now I eat natto at school lunch with my friends.
