Picture this: kimono-clad locals, tranquil streets peppered with claywalled buildings, street-food vendors selling sweet-potato snacks, a historic bell tower ringing four times a day. Welcome to “Little Edo,” as the locals call it. Time seems to stand still at this town, which preserves a 19th-century atmosphere, and that’s exactly why urbanites descend upon it when ultramodern Tokyo feels too, well, modern. Immersing yourself in tradition has never been so easy.
