Positions
North Korea
Kikuchi has been a staunch advocate for dialogue in relation to North Korea's nuclear program and their diplomatic crisis with the United States of America. In August 2017 he expressed his hope that the Japanese government would undertake "an initiative of dialogue that involves all the sides concerned in this crisis to find a diplomatic solution". He also asserted that dialogue remains "the only solution to peaceful coexistence in this part of Asia". He also accused "new political leaders" of exploiting the confrontation for their own political purposes and called for renewed negotiations.
Evangelization
Kikuchi supports missionary and evangelization efforts. He affirms that it is vital to "sow and witness the Gospel in our society today" though ponders on "where and how to evangelize" in the community. Kikuchi continues that "it is up to us to proclaim and witness the joy of the Gospel to mankind today. The grace of Christ sustains us and guides us in this journey" to bring His message to others. Kikuchi spoke on evangelization during the visit of Cardinal Fernando Filoni to Japan in September 2017 and expressed his hope that evangelization efforts on the part of the faithful would be "humble" but bold and direct.
The environment
Kikuchi is a strong advocate of environmental protection and wrote a piece for Asia News in support of the pope's encyclicalLaudato si'. The bishop said that in the piece that it was the role of all Christians in the protection and development of the environment with the proper allocation of resources on an equal level. He further asserted that "we must act to protect the lives of future generations" if "environmental degradation" went unchecked and too far. He further elaborated that the encyclical provided a "solid foundation" to be built upon for committing oneself to environmental protection and activism.
