The Japan Evangelical Missionary Association publishes a prayer guide entitled "Operation Japan." The following is my summary of their description of the Aichi prefecture:
Eastern Aichi occupies the southern tip of the Kiso Mountain Range with plains on the east and west. The climate is mild with a lot of rain, but Winter brings much drier weather. Aichi has the fourth largest population of all the Japanese prefectures. The capital city of Nagoya lies midway between Tokyo and Osaka. It has become an economic and cultural force in Japan. Agriculture is the leading industry with a gross product that ranks sixth in the nation.

In 1875 Eikichi Ohara from Aichi came into contact with a Southern Methodist Missionary in Yokohama, was baptized, and returned home. The following year the missionary came to Ohara's home town to start a preaching outreach which resulted in the first church to be established in the region.
Today, there are still four cities in the prefecture with only one church each. There are 34 towns and villages in the prefecture that have no established Christian church. Eleven of those towns have a population of more than 20,000.
