KO-D無差別級王座
In 2016, Takayama began working primarily for DDT Pro-Wrestling, and in April 2017 won both the KO-D Tag Team Championship with Danshoku Dino and the Right to Challenge Anytime, Anywhere contract for the KO-D Openweight Championship. He lost the contract to Yasu Urano on May 4, after suffering a spinal cord injury. Because of the injury, Takayama and Dino were stripped of the KO-D Tag Team Championship on May 9.
