If you're spending some time in the Toyko area then be sure to put a day aside to visit Kawagoe. The city can be reached in only 30 minutes by train, making it the perfect destination for a day trip. Kawagoe is well known for its rivers (Kawa means "river" and Goe means "over") and is often referred to as "Little Edo" because the main street is said to retain the ambiance of the town during the Edo Period (1603-1867). Try scheduling your visit to coincide with the Kawagoe Festival, help for two days on the 3rd Saturday and Sunday of October.
