They made their international debut at the 2003 IWCC Trophy in the Netherlands. These were the first ODI matches played by any Japanese team, with the Japanese men's team yet to play at that level. They did not meet with much success though, losing all five matches and giving away an incredible 104 extras in their match against The Netherlands. They were bowled out for just 28 against Pakistan in that competition, with 20 of those runs coming in extras and just 8 from the bat, with the openers top scoring with 3 runs apiece.
Their return to international level did not come until September 2006 when they faced Papua New Guinea in a three match series of one day games to decide which country would represent the East Asia/Pacific region in the World Cup Qualifier in Ireland some time in 2007. Japan showed some improvement from the IWCC Trophy, but still lost all three games.
