This was our first real day in Tokyo.
Japan is an incredible country, and I highly recommend Tokyo as the first city a traveler should visit. Most people speak enough English to help you out, and the young people could probably beat you on any English exam you had to take, but there is still a completely different culture.
Unlike North America or Western Europe, Japan has a whole different set of culture, religion and food, and this is just the shock you should look for if you're travelling.
We spent the day just wandering around the part of town we were staying in - Asakusa.
The highlight of this day, and the greatest temple we saw in Japan was Senso-Ji Temple. It is a huge complex, with a great market leading up to it. Admission is free, and the temple grounds are never closed.
