Japan proved a cut above in its last friendly before next year's Asian Cup, beating Kyrgyzstan 4-0 on Tuesday.

A second-minute strike by national team debutant Ryosuke Yamanaka set the tone, with Genki Haraguchi adding another midway through the first half and substitutes Yuya Osako and Shoya Nakajima finishing the job late as Japan dominated at Toyota Stadium.

The Kirin Challenge Cup victory improved Hajime Moriyasu's record to four wins and one draw since he was installed at the helm of the Samurai Blue, with three of the triumphs coming against South and Central American opposition.
