No, not a Constellation. That was TWA's tradmark airplane from that era.
have to do a search but I do recall seeing big 4 engine planes at Haneda when I was a kid in the 50s and I don't think they were DC-6s.

Northwest flew L-188 Lockheed turboprops and DC-7s prior to buying DC-8 jets when they were first built. Neither of the propeller planes looks like what I remember tho.
