Thanks for the well wishes, and interesting question, Peter! I'll tackle it in two (rather rambling, sorry) parts...first, as to classic U.S. shows, it's a mixed bag. When I first moved to Osaka back in 2004, a cable channel called AXN gave me my first exposure to shows like The Persuaders!, The Magician, The Immortal and a handful of others. Nowadays, AXN's content is all recent stuff, mostly CBS crime dramas and the like. Columbo is still popular in Japan and I caught nearly the entire run of original shows (and the few good ones from the later run) on network TV channels. Now, it mostly only shows up on AXN Mystery (as do things like the Joan Hickson Miss Marple, Poirot with David Suchet, the Jeremy Brett Sherlock Holmes and other, more recent British mysteries.) Occasionally, I'll come across an original Mission: Impossible or Bewitched on network TV as well, but as with classic American films, the schedule is hit or miss, and so I depend on DVD and Blu-Ray content (or YouTube and Amazon Prime) 99% of the time. There's no Turner Classic Movies or similar station here, alas - though it must be said that I have been able to see many vintage Hollywood films on NHK, and in HD as well...however, there is a tendency to repeat the same 200 or so movies over and over again. While I've never seen more than a few minutes of Key Hunter (love that title sequence!), understandably the situation is much, much better for classic Japanese television, and being a fan, you'd likely be in hog heaven, depending on the day and time (and channel), as many of the shows you mention are indeed run off and on. I haven't seen UltraQ shown here (although it likely has been), but '70s and '80s-era Ultraman is shown often enough, usually in the late afternoon kiddie slot. There's a "Samurai" chambara channel here that runs all sorts of '70s and '80s swordplay TV shows, and many of these also run during the day on over-the-air network stations, too (my wife's dad frequently catches these around lunchtime or late afternoon). I've caught the Lone Wolf & Cub and Zatoichi TV shows on cable TV at times, too. Classic anime is all over the place, and I've seen my share of Lupin the Third movies on Sunday nights over the years. Of course, all of these home-grown delights are in Japanese only, not an English subtitle or dub to be found.
