If I recall correctly, you did not go to Naoshima (the art island) on your last trip. This does not tick all your boxes, but my wife and I thougroughly enjoyed our 2 nights there a few years ago. For something unusual, you can take the LTD. EXP SUNRISE SETO (one of the very last Japanese sleeper trains) to Takamatsu and then the short ferry ride. Fly back or vv.
