Traveling in the UK
I don't think it's going to happen. The hotels are just far too expensive. Relative to Japan, train travel is roughly equivalent in price. However, the hotels are just a shitload more expensive and there don't seem to be as many package deals that essentially give you a hotel room for free for a night or two once you get the train/plane ticket. In London, you'll spend about $100 for a single before you can get a bathroom, and you'll probably spend $80 in smaller cities. In Japan, I often stayed in a single that was around $50 a night.
