Omega Zones & Cities
Reaching ALL of Japan
YWAM has developed a mapping initiative called “4K” which aims to help Christian workers all over the world better understand where the spiritual and physical needs are.
The world has been divided up into around 4,200 Omega Zones. These are determined by population, geopolitical divisions, availability of the Gospel, spiritual needs, and basic life needs.
A vision of YWAM is to establish ministries and disciple-making movements (church planting) in all of these 4,200 Omega Zones.
As most people in Japan live in urban areas, we can also highlight the most populous urban areas as Omega Cities. This is based on the Metropolitan Employment Areas (MEAs) as defined by the government.
Omega Zones & Cities in Japan
Japan has a total of 53 Omega Zones. Currently 38 Omega Zones have no YWAM ministries. There are also 17 urban areas with a population of over 1 million. 9 of these Omega Cities have no YWAM ministries.
Here you can find a table detailing all of the Omega Zones in Japan, separated by region. The Omega Cities having over 1 million people have also been highlighted.
