Brave Blossoms target key bonus point but know they must avoid mistakes against dangerous Bears.
Hosts Japan have fresh memories of facing Russia after they trailed 22-10 at half-time in England last November before securing a 32-27 test win.
Michael Leitch, pictured scoring above, was the hero on the day with two tries – both coming toward the end of each half – but the manner in which they dug themselves into a hole is the last thing they want to replicate.
Japan struggled with the Russian brawn up front in the first half, giving away five penalties plus a try following a misplaced pass from full-back William Tupou inside their own half.
