The main language spoken here is Japanese. Some people also know some English, especially in big cities like Osaka, as well as in stores and train stations.
Japan uses the Japanese yen.
A bottle of water costs around 100–200 Japanese yen (equivalent to 50 cents--1 US dollar) depending on the store or vending machine you are using.
The best meal I had this week was yesterday when I made fried rice and salad with a friend from my dorm. She is a really good cook and it's fun cooking new things with new people!
I listened to a mix of American music and Japanese music while walking or riding the train.
I went to a basketball club on Monday this week, and that was the most fun I had this week. It is really fun trying to speak Japanese while playing basketball! But the gyms are a little bit smaller over here.
