Individual information media has evolved from blogs to SNS (Instagram) and video (YouTube). Now, 'audio streaming' is the next big wave. As the audio business market grows rapidly, Karin Igarashi, an author who built a business with over 10 million yen in annual revenue using audio streaming on a single smartphone without showing her face, has compiled her know-how into a book for the first time.
◆The Rapidly Expanding Audio Business Market: Why 'Voice' is in Demand The domestic audio advertising market in Japan grew from 1 billion yen in 2019 to 3.8 billion yen in 2025—a 380% growth in just six years. While visual platforms like YouTube and TikTok are becoming saturated, 'audio streaming' has significant potential as it naturally fits into everyday spare time, such as during housework, childcare, or commuting.
◆Opportunity to Start Now! The Appeal of Audio Streaming The audio content market is often compared to the 'early days of YouTube.' With few rivals, there is a chance to monopolize early-mover advantages. No editing is required; all you need is a smartphone. You can start anytime, even while commuting or walking, with recordings taking only 15–20 minutes.
Furthermore, voice naturally conveys 'personality.' In reality, even with fewer followers than other SNS, audio streaming is said to have overwhelmingly higher participation rates in seminars and conversion rates.
◆Know-How Released by an Author Who Achieved Over 10 Million Yen Author Karin Igarashi went independent in 2024 after working at Daikin Industries and Panasonic. She used the audio platform 'stand.fm' to generate over 10 million yen in annual revenue. This book is packed with practical know-how that only someone who has achieved these results can share.
