At 1996 Olympics, although Japan won 2 matches, Japan lost in the First round. At this time, Japan beat Brazil in first game. It was known as the "Miracle of Miami" in Japan. In 1997, Nishino returned to Kashiwa Reysol and became a coach. In 1998, he became a manager. In 1999, he led the club to win the 1999 J.League Cup.

In April 2018, Japan national team manager Vahid Halilhodžić was sacked and Nishino was named as the new manager. A big challenge for Nishino was lack of time for preparation, while also being doubted because of his lack of coaching experience. Nonetheless, in the 2018 World Cup, he registered history by helping Japan to beat Colombia 2–1, the first ever defeat of a CONMEBOL team to an Asian side. His brilliant tactics continued to be demonstrated when Japan held Senegal in a 2–2 draw. His Japan lost 0–1 to Poland in the final group match, but as Japan received lesser yellow cards than Senegal, Japan qualified to the knockout stage, becoming the only Asian team to do so in the 2018 World Cup. However, his Japan lost 2–3 to Belgium despite having led 2–0, thus were eliminated from the tournament. Nishino is scheduled to step down once his current term expires at the end of July, following the World Cup. Nishino consented to take charge of the Thailand's senior and under-23 national sides on 17 July 2019, became the first Asian to coach Thailand, and on 24 January 2020, this contract has been extended until 2022.
