About いい声ボイトレ研究所
いい声ボイトレ研究所 is a Japanese-language YouTube channel run by Daisuke Mouri, a voice trainer and CEO of Voice Crew, a Tokyo company offering business voice training. The channel posts tutorials on voice exercises, clear speech, throat care, and presentation delivery, usually as talking-head lessons of 8 to 16 minutes, with a steady pace of about 50 uploads a year.
The audience is estimated to be mostly Japanese adults in their 25 to 44 range, skewing slightly toward women, who are looking to improve how they sound at work or in personal life. The website, which is a cited source of Mouri's background, describes him as a speaking coach who has been hired as a speech adviser to executives and a voice adviser to a sitting member of parliament. Median views sit near 1,800 per video, so a sponsored integration is estimated at $150 to $250 per video, which works out to roughly $20 to $35 per 1,000 median views, comparable to a $10 to $30 CPM paid ad.
Brands in voice care, speaking seminars, or business communication tools who want a focused Japanese audience should consider booking this creator.
