Travel to Tokyo and you can’t miss Hello Kitty, plastered on everything from stationery to bullet trains. Though she may hog the limelight, this theme park lets you meet her friends, too. Avoid the parties of pre-teens that take over on the weekend and visit during the week, when it’s blessedly quieter and those meet-and-greets last longer. A day in Tokyo without some pop culture fun is unthinkable, but getting your obsession going is easy.
