These places still exist, but you need to look for them. Here in Japan, some remote islands, you can travel overnight boat. I love those. There might be a speed boat or plane, but I love boarding the boat in the evening, everyone feels like having a party, sleeping in a bed and arriving fresh in the morning. (If you are in Tokyo, the nearest is Oshima Island).
There is also slow rail travel, with pretty trains, sleeper car and restaurant. I think Europe has sleeper trains too. I am also interested to go to Europe once by the trans Siberian railway.
You’d love Canada and the US. Nothing but slow travel on trains.
Flying a turboprop from Yakushima to Kagoshima on my way back to Tokyo was a highlight of my trip. Especially the domestic airport lounge with shoe-less tatami mat areas to hang out.

Europe has sleeping boats too: you can go from, say, south east of France to the Baelaric island (like Ibiza) in 12 hours overnight.
I think you miss the point. Think of the movie Titanic, where people were on the boat for a very long time, as opposed to merely an overnight trip.
There are good overnight ferries from England to France, Ireland and the Netherlands. Cheap too.
We live in France and often spend the summer visiting family in the north of England. For a family of four, it works out about the same price to take the Rotterdam to Hull night ferry (outside cabin, meals and all) as it would to go through Calais and spend the night in a hotel instead.
And then it’s 2 hours of driving instead of 8 at the end.
Even when plans take us south, we’ll often take a night ferry from Portsmouth instead of the tunnel, just because it’s a better experience for roughly the same price.
