Infrequent Sazanami limited express trains via the Keiyo Line leave once every few hours, generally at 30 past, with more frequent runs during the late afternoon and evening. This will get you to Kisarazu in as little as 55 minutes for �2490.
The cheaper and more frequent alternative is to use the JR Sobu line at a cost of �1280. A direct train to Kisarazu (last stop Kimitsu) leaves once per hour and takes 80 minutes, or else a change of trains will be required.
