Inamoto was drafted into the squad that kicks off the three-team Kirin Cup tournament against Montenegro in Shizuoka on Friday at the last minute after he signed a two-year deal with German League club Eintracht Frankfurt on Tuesday.

The 27-year-old only joined up with the team on Wednesday after flying in from Germany but insists he is fit and eager to make an impact.
