Match ends, Japan 0, Ghana 2.
Akira Nishino suffered defeat in his first game as Japan manager after losing 2-0 to Ghana on Wednesday.
Nishino played a new formation with five at the back, while Borussia Dortmund's Shinji Kagawa started on the bench in Yokohama.
Ghana - who failed to qualify for the 2018 finals - took the lead in the ninth minute through a free-kick from Atletico Madrid's Thomas Partey.
Emmanuel Boateng sealed the victory from the penalty spot on 51 minutes.
A poor display on a rain-drenched night means Nishino, 63, has some difficult decisions to make before he announces his final 23-man squad in the next 24 hours.
Japan continue their tournament preparation with friendlies against Switzerland and Paraguay ahead of their opening Group H match with Colombia on 19 June. Senegal and Poland are the other two teams in Group H.
