so i'm from england, though i now live here in japan, out in the sticks. in england, much moreso than in japan, there's a healthy history of road biking, lots of clubs and events every week, though the roads tend to be pretty poor - potholes, bad surfaces, angry drivers! and of course no mountains to speak of.
here in japan, it's hard to find races (and to get in with the racer crowd, very secretive ninja-like society!), but the road surfaces, even up on a mountain in the middle of nowhere, are incredible, almost always beautifully paved, not a pothole in sight, and you're often biking up mountain-sides next to babbling brooks and waterfalls, lush forests and rice paddies - on top of that, the drivers are generally ok. perfect for cycling.
seriously, i recommend japan for anyone planning a far-out biking holiday.
i've biked in france, switzerland too on holidays, but anyone got any other recomms? anywhere to avoid? anyone biked through cambodia, india etc?
