Hikaru Kaihatsu grew up in Myōkō City and started posting beatbox videos to YouTube in 2006. His 2010 "Super Mario Beatbox" hit a million views in a week, and two years later he quit his supermarket job to create full-time. By late 2015, his channel HikakinTV had become the most-subscribed in Japan with 2.57 million followers. He crossed 10 million in 2021 and 10 billion views by 2022. In 2023 he launched the food brand Bee, releasing miso ramen and rice bowls through 7-Eleven that sold 60 million meals by mid-2026, followed by a barley tea that moved 7.5 million bottles in two months. He co-founded the multi-channel network Uuum and now splits CEO duties at Bee while running a constellation of channels with 25.7 billion total views.
