I am. Good story about him from Japan Running News:http://japanrunningnews.blogspot.com/
There, on a course well-suited to his strengths, he hopes to run fast enough to make at least the top five. "I want to beat Meb Keflezighi," he told JRN, "because he finished ahead of Nakamoto at the Olympics. Tsegaye Kebede also outran Nakamoto in Moscow, so if everything goes right I'd like to beat him too. And of course Stephen Kiprotich."
Sounds like he's aiming high. I'll be rooting for Kawauchi, but not to beat Meb.
