The whole city around you is
full of speaking opportunities....but
you have to go out and put yourself in them.
If you are interested in reading Japanese literature, then take advantage of your time here to visit used bookstores (such as Book Off) where you can get lots of books to take back home with you for later reading. You will never have an easier opportunity to stock up on cheap Japanese books than you do right now. I've gotten quite a few good novels and non-fiction books from the used shops, often for only 100 or 200 yen each. Reading is like speaking: the more you do it the easier it gets. The first Japanese book I ever read was a pet care book called セキセイインコの飼い方増やし方 (The Care and Breeding of Parakeets). It was the sort of simple book you might find in your local pet shop. But I had parakeets, so it was useful. Before attempting regular books, though, I read
hundreds of collections of four-panel comics (4コマ漫画). After the parakeet book, I went through a couple of collections of short stories, then through about 15 detective novels by Uchida Yasuo, a half-dozen by Matsumoto Seicho, a couple of novels by Endo Shusaku, and a
big stack of non-fiction on all aspects of the Japanese criminal justice system. Recently I noticed that I live in a country with millions of Buddhists and knew
nothing about Buddhism, so I read
仏教入門 and am currently over half-way through
法華経大全. It is very nice to sit down and read a Japanese book just for enjoyment or just because you're interested in the content, instead of having to force yourself to read it as a study exercise. It also gives you tons of exposure that is very valuable for your listening and speaking as well. Most definitely work on your Japanese literacy skills and go hit the bookstores for some bargains to take home with you.
