I concur. Having been in Japan for 1 1/2 months, I can say that coverage is spotty with dismal throughput...at least with my provider (silly me for not going with NTT Docomo). I had high hopes for wireless in Japan, but service appears to be a step backwards and the costs are high. I do miss my VZW.
