BARTH Launches Heartwarming Sleep BGM Featuring Renowned Voice Actor Akio Otsuka

BARTH's New Heartwarming Sleep Soundtrack

In a delightful announcement, BARTH, the night wellness brand that promotes an elevated nighttime routine from bath time to sleep time, has revealed its latest sleep BGM titled "Heartfelt Phone Call with a Worrywart Father -105 minutes-". This new soundscape, which features the talented voice of the well-known voice actor Akio Otsuka, is set to be released on November 26, coinciding with "Good Bath Day" in Japan.

This immersive audio experience is meant to be enjoyed alongside BARTH's bath products, creating a gentle and relaxing ambience from bathing to bedtime, allowing listeners to bask in comforting moments.

The Soothing Soundtrack: A Closer Look

The newly released sleep soundtrack follows the success of the first installment, "Principal's Long Talk -67 minutes-", which aired in March 2023. In that edition, listeners were enveloped in a cozy sleep environment provided by BARTH and the comforting storytelling of Otsuka, who portrayed a school principal. Feedback from the audience was overwhelmingly positive, with many expressing how the BGM was perfect for sleep, and some wishing for its return. In response to this enthusiastic reception, BARTH decided to produce a sequel.

In the latest piece, Akio Otsuka takes on the role of a loving but worried father. In this narrative, the father engages in a lengthy call with his daughter living in Tokyo, sharing nostalgic stories and life advice, all driven by a concern for her well-being. His repetitive anecdotes gently transition the daughter into a serene sleep environment.

The second soundtrack is a comprehensive 105 minutes long, written across 35 pages and approximately 30,000 words. Designed to enhance the recommended 15-minute bathing experience, the first 15 minutes consist of a captivating monologue from the father expressing his feelings on a voicemail directed towards his daughter. The following 90 minutes are a simulated phone conversation, allowing listeners to immerse themselves in a nurturing nighttime routine that feels incredibly realistic.

Story Overview

The narrative unfolds with a father from the countryside dialing his daughter who is living alone in Tokyo. Mixing stories from his past and providing life advice, he shares his worries about her urban lifestyle. His overflowing affection leads him to repeat similar stories multiple times, serving as a gentle guide into a peaceful sleep state for the daughter.
