Though Shirakawa may be the most talked-about practitioner of this needle-happy technique, he’s certainly not alone. A quick Google search will show that there are around 500 acupuncturists in Japan specializing in this “root acupuncture” method. While this may sound like a large number, it’s worth noting that Japan boasts over 120,000 acupuncturists in total, making Shirakawa’s style somewhat rare, and perhaps adding to its allure.

In the end, it’s clear that Shirakawa’s trendy acupuncture method isn’t just about relieving pain. It’s a deeply personal experience, where the needles are said to align more than just your muscles—they realign your energy, lift away your bad luck, and might even bring you closer to inner peace. And with a legion of satisfied celebrities vouching for its effectiveness, it’s no wonder this unconventional practice has gone viral. Therefore, although the concept of transforming into a human porcupine may not appeal to everyone, it appears to be highly effective for those who dare to attempt it.
