Briefly, the relationship between the Korean and Japanese Christianity could be established under the influence of Treaty on Basic Relations between Japan and the Republic of Korea which was signed on June 22, 1965. The new era for the relationship between the two countries exchanges also the relationship between the Korean and Japanese Christians. The starting point of the development for the relationship between the Korean and Japanese Christianity is “The Confession of Japanese Christian Denomination’s Responsibility at the Second World War” which had pronounced by Masahisa Suzuki, the chairman of UCCJ, on March 26th 1967. Thus the Korean Christianity, in approaching to the national unification, needs the partnership of the world churches, the brotherhood in Christ Jesus. The world churches sympathized with the suffering of the Korean Christianity and fully agreed with us and supported our will for the peaceful reunification. Since the ‘Tozanso Consultation’ in October 1984, they have been appealing for the reunification of Korea to the World. At the First Glion Conference in September 1986, the South-North Korean Christians gathered to share the Holy Communion and worship God in front of the world churches. Though there were structural limits with the international political and ideological system, the peaceful reunification of the Korean peninsula became the most important international issue. It is the fruit of the South-North Korean Christianity who worked together to overcome the barrier. And it is the result of the world churches and many people around the globe who tried to alleviate the sufferings of the Korean people. As Japanese Christians’ view on the division issue of the Korean peninsula, they have the responsibility or feeling of guilty. The division of the Korean peninsula was due to the split occupation by the United States of America and the Soviet Union. Furthermore, in accordance with Japanese view, it is due to Japanese colonial dictatorship over the Korea. Japanese Christianity analyzed “A Basic Treaty of Korea and Japan” and criticized that Japan fix the division of the Korean peninsula. Even though Japanese Christians tried to look at the North Korean Christianity and its people with the object view. With this regard, we conclude that we have to approach to the Korean division with the historical, scientific and practical view. Besides, with the regard of objective view on the North Korea, we concluded that we should enlarge the theological area of ‘modesty view’ in the Korean Christianity.
