Marcus Smith's standout performance led England to a decisive 52-17 victory over Japan in Tokyo in their summer tour opener. Smith scored a try and set up two more before receiving a yellow card in the second half. England's eight-try display saw contributions from Chandler Cunningham-South, Alex Mitchell, Ben Earl, Harry Randall, and Sam Underhill. Despite Japan's early lead through a Seungsin Lee penalty and late consolation tries from Koga Nezuka and Takuya Yamasawa, England dominated the match. Charlie Ewels was red-carded late in the game for a dangerous clear-out. England now face tougher challenges with upcoming tests against New Zealand.
