Greetings!
I would like to gather as much information about various things about Japan before I leave for my trip which is sometime during next August.
The trip is only for a few days, but this is my first time ever leaving home outside of the US, and I am very excited.
I have a good concept of the Japanese language, but not to the extent of pure fluency. I can read, write, speak, and email in Japanese. Hence, there are mistakes that I make at times and I don't mind being corrected.

The information that I would like to know is:

-Would I need to get any shots or vaccines before leaving?
-Due to the rising temperatures in Japan, what would be the best clothing for those really hot days?
-Since I am unsure of where I am exactly going to be in Japan, does anyone know of any inexpensive bookstores in Japan? Maybe a secondhand book store? (I love to read Japanese books by the way!)
-Has anyone with asthma visited Japan? And if so, was their asthma ever effected?


Thank You for taking the time to read my post.
Have a great day!!
じゃ、またね！！
