I can pick either AB or HJ in row 25 going and 22 returning from Tokyo. My wife likes the window and I like the aisle. Any suggestion as to best side? Normally I sleep on my left side.

Row 25 going is the only row with seats left together not in the middle. I'd prefer a different row, I think, but there is a lot of space behind the row before the start of the main cabin. Unless people congregate there and talk, that could be a plus.
