San Francisco’s Japantown, America’s largest, is in the midst of a makeover, complete with direct-from-Tokyo bookstores and toy shops, and soon, a three-story Japanese pop culture center. Our pick for an overnight: the new Hotel Tomo, where lobby vending machines sell T-shirts and watches, guest rooms have manga murals, and a shabu-shabu restaurant operates on-site. Reserve a game suite and watch Godzilla on a monster six-foot screen. 888/822-8666;; doubles from $149; game suite $550.
