This is the biggest library in Japan. It corrects all of the books, newspapers and magazines. I sometimes come here to look for books I need or my research. The books I need in my research is not so common, so in many cases I have to buy by myself or ask my professors, and coming here is my last choice. The reason I do not want to come here often is just it is not close my home. This place is very clean and well organized. So you can find what you need easily. If you were a researcher or someone who needs special knowledge or information, I think you might come here at least once. This is in the center of Tokyo and easy access on trains. You can enjoy other tourist spots near here. You can drop in some of them after this visit. You can read as many books as you want for free.
