Both NRT and HND have experimented with streamlined transiting for passengers coming from the US, but those trials have been "off again, on again." I think all passengers need to go through security now. Perhaps someone can post a recent experience. Don't expect past experience to be a guide to future performance - as you can see from the anecdotes in these threads:

NRT
Transfer security at Narita

HND
International to International connection at HND
