Japan will play Mozambique in a hastily-arranged final pre-World Cup friendly on Thursday as Takeshi Okada's side seek a much-needed confidence boost ahead of Monday's opener against Cameroon.

Japan have suffered four consecutive defeats ahead of a fourth consecutive World Cup campaign and face a tough task to reach the knockout stage in a group which also contains Holland and Denmark.

Mozambique lost 3-0 to Portugal in Johannesburg on Tuesday and will head to Japan's base in George for the behind-closed-doors match, which will be split into three 30-minute periods.
