This one was built for Japan (so RHD).It’s also only 3.8m high, about 0.2m lower than the others.
From what I managed to translate from the web pages below, it seems that when this vehice was imported into Japan it was not road legal due to being oversize.
as a result of this it was used to take visitors around the "central park" which I believe to be a theme park.
Some sources suggest that a second Jumbocruiser was built for Japan, Please contact me if you know more.
