When I was living in Tokyo, it was theoretically possible to get from where I lived to the center of the most popular downtown hangout spot in 20 minutes by train. In reality, though, you had to tack on between 5 and 30 minutes of random delays depending on the train schedules and what time it was. If you're sitting in your living room, and decide "I want to go to $place, it's a 45 minute trip if I leave now and a 20 minute trip if I leave in an hour" I think you could make an argument either way. Within downtown Tokyo, you can often beat the train by just walking briskly from point to point, and almost always beat it by riding a bike. Maybe the guy above you is focusing entirely on those worst case walking/schedule-based delays and you're focusing entirely on the best case.
