The Suntory Cup is a defunct invitational men's tennis tournament that was held at the Yoyogi National Stadium in Tokyo, Japan from 1978 to 1986. The indoor tournament was played in April each year and consisted of a four-man draw. The event was not recognized as an official tournament by the Association of Tennis Professionals (ATP) or the International Tennis Federation (ITF) but still attracted the world's leading players due to the financial rewards. Jimmy Connors won the event a record four times. The 1983 edition was noteworthy as it was Björn Borg's last tournament before his retirement.
