KO-D Openweight Championship
At Budokan Peter Pan: DDT 15th Anniversary, Harashima and NJPW's Togi Makabe defeated Shuji Ishikawa and BJW's Ryuji Ito. Afterwards, Harashima formed a new veteran stable with generational rivals Kudo and Yasu Urano to go after the villainous Team Drift (later Team Dream Futures) stable of Keisuke Ishii, Shigehiro Irie and Soma Takao. On September 30, the veterans, now known collectively as "Urashimakudo", defeated Team Drift in the first six-man tag team match between the two stables. In October, both Kudo and Urano were sidelined with injuries bringing the future of the stable into doubt, however, the stable was kept alive when Hiro Tsumaki joined the veteran stable on October 21 as a replacement for the injured members. On November 25, Jarashima returned for one night only as part of Poison Sawada Julie's retirement match. Urano returned in December and on January 6, 2013, Harashima and Urano defeated Mikami and Tatsumi Fujinami to win the KO-D Tag Team Championships. On January 27, Kudo announced that he was returning to the ring in February. This led Fuma (formally Hiro Tsumaki) announcing that the stable was now called Urashimafuma and he was a full-time member. However, Yasu Urano ended up turning on Fuma, kicking him out of the stable and welcoming Kudo back. After four successful title defences, Harashima and Urano lost the KO-D Tag Team Championships to Hikaru Sato and Yukio Sakaguchi. Harashima quickly bounced back from the title loss, winning the Hard Hit Grappling Tournament on May 19 and entered the 2013 King of DDT On July 7, Harashima defeated Kenny Omega in the finals of the tournament and earned the right to challenge the KO-D Openweight Champ, Team Dream Futures' Shigehiro Irie. On August 17, during the first day of DDT's 16th anniversary weekend at Ryōgoku Kokugikan, Urashimakudo lost to Team Dream Futures in a trios match. The following day, at Ryogoku Peter Pan 2013, Harashima won his fifth KO-D Openweight Championship. On October 20, Harashima won the Ironman Heavymetalweight Championship for the first time since 2002 whilst successfully defending his KO-D Openweight Championship against Danshoku Dino. On November 4, Harashima continued his dominance, defeating Antonio Honda for the DDT Extreme Championship., becoming a triple crown champion in the process. Harashima lost the Ironman Heavymetalweight Championship to Yukio Sakaguchi on December 12 but regained in on December 23 during a KO-D Openweight Championship defence. On December 31, Harashima finished his extremely successful year by winning Tenka Toitsu! 3 Organization Strongest Determination Tournament, a one night knock out style tournament put on by DDT, BJW and Kaientai Dojo. After losing the Ironman Heavymetalweight Championship to Masa Takanashi on January 13, 2014, Harashima successfully defended his KO-D Openweight Title against Takanashi on February 23. After the match, Kudo quit the Urashimakudo stable and challenged Harashima to a match for the KO-D Openweight Championship. On March 1, Harashima lost the DDT Extreme Championship to Danshoku Dino. Harashima's misery continued as at Judgement 2014, Kudo defeated Harashima to win the KO-D Openweight Championship.
