 On January 4, 2013, at Wrestle Kingdom 7 in Tokyo Dome, Otani made a special return to New Japan, when he replaced an injured Daichi Hashimoto in a tag team match, where he and Keiji Mutoh were defeated by Hiroyoshi Tenzan and Satoshi Kojima.Beginning in September 2015, Otani downgraded himself back to the junior heavyweight division, proclaiming that the division had "lost its way" and "needed more heart".On September 23, he reformed his junior heavyweight team with Tatsuhito Takaiwa and defeated NWA International Lightweight Tag Team Champions Takuya Sugawara and Brother Yasshi to win the titles, the team's fourth tag team title overall and their first in 15 years.
