Shiojuku’s Latest Venture: AI-Generated Music Video

Shiojuku, a prominent learning media for public relations operated by Kyodo News PR Wire, has launched a themed music video titled 'What Day Is It Today?' on YouTube as of September 3, 2026. This project utilizes cutting-edge AI technology for both the song and visuals, with the Shiojuku editorial team responsible for everything from lyrics to video editing.

A Significant Date in PR History

September 3 marks a critical anniversary: it was the day Shiojuku led Japan into a new era of public relations with the launch of its first press release distribution service in 2001. Celebrating 25 years of innovation in the field, the release of the music video aligns perfectly with this milestone.

The Cultural Impact of 'What Day Is It Today?'

On platforms like X (formerly Twitter), posts beginning with 'What Day Is It Today?' or hashtags related to special occasions have become a cultural fixture, with corporate accounts promoting relevant anniversaries, and individuals engaging with trending topics. Recently, about 900 such posts have been reported daily, with a total of 25,879 occurrences just in the month prior to the release (August 4-31, 2026), underscoring the relevance of this phrase in daily online conversations.

The song serves as the theme for Shiojuku's irregular short video series, which dives into the PR aspects of various commemorative days. The lyrics encourage audiences to question why specific dates are significant, shedding light on how these events shape perceptions and narratives in everyday life.

An Engaging and Informative MV Experience

The music video, running 2 minutes and 33 seconds, is a visually engaging piece created using animation generated by AI. It depicts a character flipping through a calendar and discovering small 'whys' in familiar settings, in accordance with the song's lyrics. This compelling narrative draws viewers into a reflection on the significance of commemorative days and PR strategies.

Why This Initiative Matters

Creating a music video as a public relations learning platform is not an arbitrary choice. Anniversaries have long been a pivotal tool for companies to generate discussions about relevant topics. Shiojuku's ethos of exploring the 'whys' behind commemorative days illustrates a shift from merely consuming such information to understanding its roots.

For a company that has diligently provided information for 25 years, this venture is an experimental attempt to engage audiences through the prevalent realms of social media and music.

Musical Innovations Available for Public Use

Shiojuku has made the 15-second and 30-second versions of the song accessible for public use in anniversaries, as long as the credit is given. This move is designed to encourage inclusion and creativity in how people celebrate special days. Further details about usage conditions can be found on Shiojuku’s website.
