japan has amazing depth.
japan has 168 at 1:04:30 or better this year in the half marathon.
usa has only 18 at 1:04:30 or better this year.
the one thing bad about japanese running is no runners at the very top as 62:00 is the fastest japanese time this year which is 109th on the 2008 yearly list.
the japanese national record is 60:25 which is 88th on the all time list.
in the mens marathon all time list only kenya and ethiopia have more runners in the top 100 all time list than japan which has 6 in the top 100 led by a 2:06:16.
the japanese women marathoners are the top country with 20 in the top 100 followed by kenya and russia with 11 each then ethiopia with 9. and with standouts akaba and kinukawa soon moving to the marathon japan should stay on top for a while.
