This limited express called Kamome runs from Nagasaki to Kitakyushu and was the first train I rode that made me feel in awe of Japanese style and technology. The seats are all soft black leather the floor is parquet and the walls are off-white (no first/second class disparity). There is a small pullout table hidden in each seat's armrest. Each pair of seats has a foot switch that can be used to rotate the seats to face the other direction making a group of four. If all four seat's tables is taken out then it will make one later table.  And of course, the ride is smooth, fast and quiet. Compared to the dirty plastic, chewing gum patterned carpet, diesel fume belching trains of the UK, it felt like something out of the distant future and still shines to this day.
