Virtual necessity: can VR revitalise Japan's ailing arcades?

One day, on my way past the outskirts of Kabukichō – Tokyo's red-light district, infamously depicted in the Yakuza games – I spot a curious advertisement. At first glance, it looks like nothing out of the ordinary: a woman cheerfully donning a VR headset, with kanji lettering welcoming passersby to come in and try the technology for themselves. As my eyes wander to the logo in the corner, I realise that the poster is promoting Soft On Demand – one of Japan's biggest porn, or "AV" (adult video), companies. A stone's throw away is Bandai Namco's massive VR Zone complex, an indoor, 38,000 sq ft all-VR theme park that opened just over a year ago. And further south, on the artificial island of Odaiba, Sega recently cleared out a massive room in its Joypolis amusement park to make space for Zero Latency VR, a "warehouse scale, free-roam, multiplayer virtual reality entertainment" where a team of zombie hunters are equipped with "military-grade" motion-tracking backpacks and let loose on the undead with an arsenal of plastic firearms.
