The best way to enjoy Harajuku is to first walk down the posh shopping street of Omote Sando Dori.
Take a turn at the GAP onto Meiji Dori
You soon arrive at the archway to the main pedestrian street of Takeshita Dori dense with the crowds of Harajuku
Unlike Omote Sando, here you can find some inexpensive, frivolous shopping.
People watching is the main draw in Harajuku, to see and be seen.
