Join a team to Prayer Walk through cities in this least-reached country. Japan, with a population of over 123 million, is home to 26 Unreached People Groups (98% of its population). Why walk & pray? Many around the world do not know the Living God. We may not know the best way to reach them, but God does. Jesus said, “God is spirit” (John 4:24). So, we should use spiritual tools to reach our spiritual objective of introducing people to Christ. Prayer is a major spiritual tool!
