I'm stuck in Japan right now, but there is so much to see!

I'm here for a conference, but the city is so beautiful and fun I don't want to leave. I'll be here for a while longer and want to explore more. <br><br>Any tips, please! What should I see? What should I eat? How can I get around? I've been here for 4 days and have seen a good amount, but there is so much more to see.<br><br>**I'm already visited:**<br><br>* The Tokyo Tower (very fun!)<br>* The Tokyo Skytree<br>* Shibuya Crossing <br>* Asakusa (very nice park!)<br>* Meiji Shrine<br>* Harajuku <br>* Tsukiji Outer Market (great sushi!)<br>* The Japanese Fish Market (bleeding fish!)<br>* Aizome Street (amazing street food!)<br>* Tokyo Station (very cool!)<br>* Shinjuku (the neon lights are so cool!)<br>* Akihabara (very cool tech district!)<br><br>Next places to visit?
