Ootsuka Akio’s Latest Sleep BGM from BARTH Takes You on a Heartwarming Call with a Worried Father!
The popular voice actor Ootsuka Akio, renowned for his roles as Jigen Daisuke in Lupin Sansei and All For One in Boku no Hero Academia, is back with the second installment of a sleep BGM series from Earth Pharmaceutical’s night wellness brand, BARTH. This latest offering, titled “Long Phone Call with a Worried Father -105 Minutes-“, was released on November 26th, coinciding with “Ii Furo no Hi” (Good Bath Day), a day dedicated to the enjoyment of baths. Fans who missed out on the first installment will be delighted to hear that “The Principal’s Long Speech -67 Minutes-” has also been re-released for a limited time.
The Beloved Principal is Back, This Time as a Doting Father
BARTH Sleep BGM “Long Phone Call with a Worried Father -105 Minutes-“
BARTH’s sleep BGM series first captivated audiences in March this year with “The Principal’s Long Speech -67 Minutes-,” which was also available for a limited period. In this first installment, Ootsuka Akio, portraying a principal delivering a lengthy speech, aimed to create a comfortable sleeping environment, especially when used in conjunction with BARTH’s bedroom reed diffusers. The BGM received widespread acclaim, with listeners praising it as “perfect for sleep,” expressing a desire to “keep listening if Ootsuka-san is the principal,” and frequently asking for “more installments.” Responding to this overwhelming positive feedback, BARTH decided to produce a second sleep BGM.
A Familiar Yet Comforting Scenario: The Long-Distance Call
In the second installment, “Long Phone Call with a Worried Father -105 Minutes-,” Ootsuka Akio takes on the role of a concerned father. The storyline unfolds as a worried father, living in the countryside, engages in a long phone call with his daughter who lives far away, showering her with an abundance of love. The BGM aims to deliver heartwarming moments from the time of bathing right up until sleep.
The father, calling his daughter who lives alone in Tokyo, expresses his concern for her well-being while interweaving personal anecdotes and life advice. His profound love for his daughter leads him to unintentionally repeat similar stories multiple times, gently guiding her (and by extension, the listener) into a cozy, sleep-inducing space.
More Than Just a BGM: An Immersive 105-Minute Experience
This new production, exceeding its predecessor, boasts an impressive total length of 105 minutes, with a script spanning 35 pages and approximately 30,000 characters. To align with BARTH’s recommended 15-minute bathing time, the initial 15 minutes of the BGM feature “Father’s Monologue,” where he leaves heartfelt messages for his daughter on her answering machine. Following this, 90 minutes of “Call with Father” are recorded, timed for the period between bathing and falling asleep. The BGM is meticulously crafted to make listeners feel as if they are the daughter themselves, allowing them to fully immerse in their night routine. We highly recommend enjoying this heartwarming relaxation time, from bath to sleep, accompanied by Ootsuka Akio’s soothing voice as the caring father.
BARTH’s official X (formerly Twitter) account has also released the full transcript of the BGM, encouraging listeners to follow along and try to spot the ad-libs that Ootsuka Akio seamlessly incorporates throughout his performance.
