I wrote an article for the December 2006 issue of the Japanese DX Magazine 
"Five Nine" with an analysis of the JA path on Topband (over 9.000 km).
The JA's are active every day in each call area (when the BY jammer is not 
killing the band): in my 160 log there are  400  "different" JA stations.
So Pete, that's a feel of how popular is really 160 meter band in Japan.

Best 73
