Kazuchika Okada
At Wrestle Kingdom 14 in Tokyo Dome, Nagata was again on the pre-show, this time in a tag team match alongside Nakanishi to take on Tencozy, which they lost. This would be Nakanishi's final match in the Dome. On February 22, Nagata teamed up with Nakanishi &amp; Tencozy in Nakanishi's retirement match. They faced Chaos' Kazuchika Okada &amp; Hirooki Goto, and NJPW's Hiroshi Tanahashi &amp; Kota Ibushi in a losing effort when Nakanishi was pinned by Tanahashi following a 'High Fly Flow' (Frog splash). In June 2020, Nagata entered the 2020 New Japan Cup, which was delayed due to the COVID-19 pandemic, defeating long time rival Minoru Suzuki in round one, before losing to Kazuchika Okada in the second round. Suzuki angered by the loss, declared war on Nagata, with Suzuki eventually beating him in a singles match on Day 4 of New Japan’s Summer Struggle series, ending their feud. With Nakanishi retired and a smaller field in the 2020 World Tag League, Nagata didn't make it into the tournament.
