These machines once stood in front of friendly candy shops, familiarly called “dagashiya” in Japanese, found near schools in every neighborhood in Japan. Thirty years later, they have been replaced entirely by smart phone games, Nintendo or PlayStation, etc. But this museum of old game machines pulls in a steady stream of locals, young and old. What’s the reason? Nostalgia or novelty? In Japan nostalgia lures middle-aged people who are financially well-off than the other generations. Nostalgia is a key to a new business nowadays.
