Robot Start Inc. (Headquarters: Shibuya-ku, Tokyo; Representative Director: Yoshihiro Nakahashi; hereinafter 'the Company') has implemented Podcast advertising support for Jeans Kobo Ogata, which develops the denim brand 'isa' originating from a dedicated jeans factory in Kuroshio Town, Kochi Prefecture.
Through this initiative, significant results were confirmed, ranging from increased awareness to actual purchasing behavior, including improved EC sales and an increase in visits by younger customers.
[Background]
Jeans Kobo Ogata established its original brand 'isa' in 2009 as the only dedicated jeans factory in Kochi Prefecture, based in Kuroshio Town. The factory provides high-quality denim products with skilled artisans handling everything from planning to sewing in their own workshop. Meanwhile, reaching out to the younger generation to further expand brand awareness and strengthen EC sales had become a challenge.
[Implementation Summary]
With the support of Robot Start Inc., Jeans Kobo Ogata conducted a nationwide distribution utilizing Podcast advertisements from April 2025 to March 2026.
Programs with high affinity for listeners, including younger generations, were selected, and the campaign was designed to convey the brand's worldview and story through audio advertisements.
[Results]
The following results were confirmed as a result of this measure:
- EC Sales: Achieved 125% compared to the previous year.
- Store Visits: Increase in visitors from outside the prefecture (reported by store staff).
In particular, notable effects were seen in expanding awareness among younger generations, with whom there had been little previous contact, and in promoting visits to physical stores.
[Features of Podcast Advertising]
Podcast advertising is a medium where listeners engage for long periods and consistently, characterized by the natural transmission of brand messages through trust in the personalities. In this case, it led to concrete behavioral changes such as EC purchases and physical store visits, rather than just awareness expansion.
[Future Outlook]
Robot Start Inc. will continue to promote the use of Podcast advertising as a method to support the nationwide expansion of regional brands. We will continue to contribute to creating results in both awareness and purchasing through communication designs that convey brand worldviews and stories.
