Nice. Japanese literature is world class. Not to mention how many books written by foreigners about Japan are really good too. I Am a Cat by Natsume Soseki. The wind up bird chronicles. Anything by Haruki Murakami. There's some good murder mystery, surrealist, pop, and just plain weirdness also. Can't remember the names though. Have fun!

Load up my Kindle with multiple books of varied genres. Try to get ones that are set in the country you are flying to. It puts you in the mindset of the locale and helps to immerse yourself in the place you are going to visit.
