We planned to go to Tokyo from Dec 28th - Jan 1st. Since lots of museums and shops are closed on those days, and we lack of other options. So, what do you think we should do to spend end of the year in Tokyo?
If you are interested in Japanese culture such as traditional buildings, I would like to recommend visiting Senso-ji where is in Asakusa. (http://www.senso-ji.jp/) There are many kinds of shops including food stalls, so you can try to eat traditional local snacks and buy some souvenirs.
