Here is another user question; "did you find it easy to make Japanese friends at japan?"
Short answer: "yes!" ☺
The best way to make friends and meet new people in my opinion, is to go to small student bars in waseda and takadanobaba, and people will quickly start speaking to you even if you don’t take the initiative... as long as you speak a little japanese its very easy to start making new japanese friends. ☺
Also make sure you get out of the dormitory on your own, as you are hard to approach for a japanese person if you are with a bunch of foreigners. It is a lot easier to meet people if you are alone or maybe 2 people and not afraid to start a conversation.
I recommend this very small but cozy bar called “10 degrees bar” near takadanobaba station and kandagawa river. It is a student bar created and run by Waseda students, and they are all very nice people ☺http://tinyurl.com/2992e5y
Here they have made the famous ”rainbow drink” and as everything else in the bar it is 500 ¥ ;)
Also Waseda will arrange several cultural events but beware that at these events mainly foreigners show up. Alternatively there are many student clubs at Waseda that focuses on international students and partying. But chances are that at these clubs everyone will be speaking English which it great for making new international friends...but that’s not why you came to japan is it?
Get some friend, even if(or maybe espacially) they are not from Waseda, they will take you places that the others don’t know about, and to places that are not in “Lonely Planet” ;) and the will be the ones that inadvertently help you speak more fluently Japanese. They are also the ones most likely to be able to help you with non-university-related issues like getting a job in japan later and the likes. It’s always good to have a network outside of the “academic sphere” in japan. And you will no doubt find that “shakaijin” (working people) are another “sort” of Japanese that you are used to at university.
