Atsushi Onita
Upon his retirement, Kobayashi has remained involved in puroresu, currently as caretaker of the NJPW Dojo. He occasionally wrestles in legends matches, including a series of matches in 2011 against Sayama and a team with him in 2013 against Atsushi Onita (who led the AJPW junior heavyweight division in 1983, before Kobayashi showed up). He would also do color commentary for NJPW shows.
