For someone whose travels were limited to South Asia and Europe, Japan was different. I cannot describe the difference in words, you have to go and experience it. A mixture of ancient culture seamlessly juxtaposed with modern technology. The hustle of Tokyo and the relatively relaxed way of life in the ancient capital Kyoto.
Tokyo is the largest city in the world and it shows in the crowds and also the efficiency with which the city operates. Shinkansen or the bullet train form the backbone of intercity travel. Mt. Fuji, a mere hour away by train (and a long trek up of course) beckons in the summer months.
Kyoto will mesmerize you with its beautiful temples and awesome food.
