Thank you in advance for sharing your experience, ;)

Normally I do sports in weekend with friend.
You can find lots of get together around Tokyo among the foreigners and Japanese people. Where you can practice Japanese language and share cultural knowledge.
You can go sightseeing. Some recommended  places around Tokyo are Odaiba, Inokashira-koen, Ueno-park or doubutsukoen, Roppongi-hills, Shibuya/Harajuku window shopping. You can go for outdoor in Okutama, do BBQs and camping. Okutama can be visited by train.
