Program Overview

Program Name: 'Sakamaki-san and the Mysterious BAR'

Broadcast Schedule: Starting July 2, 2026 (Thursday) at 9:54 PM JST; 6 consecutive weeks

Cast: Higuchi Hina and others

Official Website: https://www.bs4.jp/sakamaki-bar/

A mysterious bar quietly exists in an unknown location. 29-year-old Shizuku Sakamaki (played by Higuchi Hina), troubled by work, love, and relationships, stumbles into this surreal space.

As Shizuku takes a sip, anthropomorphized characters representing the characteristics of the alcohol she drinks appear before her. These quirky, witty 'alcohol personifications' gently comfort her heart and offer insights into living authentically. A 5-minute human drama dedicated to adults navigating modern life.

Background: Creating an Engaging SNS Campaign Aligned with the Drama's Universe

In recent years, promotional strategies for dramas, anime, and IP-based content increasingly require interactive elements that encourage spontaneous audience participation.

BS Nippon TV has launched the 'Heartbreak Drink Diagnosis' as a companion campaign for 'Sakamaki-san and the Mysterious BAR,' enabling viewers and social media users to easily engage.

YONDE designed both the questions and results based on the drama’s concept of 'anthropomorphized alcohol characters.' The diagnostic content is structured not just as a standalone quiz, but as a foundation easily expandable into social media posts, short videos, and cast-related campaigns.

Additionally, YONDE handled the illustration design, creating nine distinct original characters, each uniquely tied to a diagnosis result.
