The Yakuso series is music therapy that combines inspirational messages that have been analyzed and originated from the aspect of cognitive psychology, with good-quality music. There are 36 million times of narration recorded at the volume, frequency, and speed that make it audibly indiscernible for 50 minutes within the songs, and the (audibly indiscernible) narration becomes a suggestive message that naturally creates subconscious awareness. During the clinical trial for 2 years, about 80% of people answered that they felt the effects.
