Majority of the travelers or tourist would make their way here via the JR Yamanote line and exit at the Harajuku Station (原宿駅). From here, the first thing you would notice is the massive crowds surrounding the entire area. A large majority would be mostly teenagers who come here to shop or just hang out. The weekend is the best time to visit Harajuku and you should spend at least half a day there. Go in the late mornings till the late afternoons.
