The main language that is spoken in Japan is Japanese. Japanese is the official language of Japan. English is the second-most-spoken language in Japan since it’s a common class for students in grade school, but many people struggle to speak it and don't have a chance to practice after they graduate.
The currency used here in Japan is the Japanese Yen (JPY). Currently the USD to yen ratio is $1 USD to about 159円.
A bottle of water costs about 120 yen at the convenience store and about 140 yen in vending machines. That makes it about $0.76-$0.88 cents.
The best meal I had this week was hot pot at a Chinese chain called Haidilao. I had it with a couple of friends and I loved it. I had pork belly, beef, fish, veggies and a really good pudding.
I listened to a variety of music. When it comes to music, I haven’t really been listening to anything new. But when I’m out in public, it's common to hear K-pop, J-pop, RnB and Hip-Hop.
