Japan is an old country, especially compared to a newcomer like the United States. As such, there's a lot of history to accommodate in a relatively small space. Appreciably, they try to conserve this history whenever possible, meaning that your liable to stumble into multiple unexpected temples throughout the cities. Surrounded by all the modern trappings you can still readily find your zen zone.
Toyouke shrine, in the Nekozane area of Urayasu, is a beautiful structure and integral part of the cultural heritage of the area. Every four years there's a huge festival in the town called the Urayasu Sanja Matsuri, which includes Toyouke shrine among the three celebrated.
All was quiet when I visited this time, but I was lucky enough to catch the Sanja Matsuri in 2012!
Here's hoping I can catch the next one in 2016~
