Innovative PR Campaign Drives Women to Shinagawa Sauna's Special Event

In an exciting initiative running from March 3 to March 5, 2026, HIDANE Co., Ltd., based in Yokohama, Kanagawa, successfully managed a collaboration with Shinagawa Sauna, located in Shinagawa, Tokyo, to promote a special Women’s Day event titled “Totonou Spring Hair Festival.” This event witnessed an overwhelming response from women, with a total of 948 attendees over the three days, showcasing how experiential marketing can effectively engage consumers.

Event Overview

The exclusive Women’s Day event transformed a male-only facility into a welcoming space for women, providing a unique opportunity that was highly sought after, often selling out quickly. Attendees participated in a variety of activities while immersed in an atmosphere tailored to their interests. The strategic placement of products in essential areas such as shower rooms and powder zones encouraged spontaneous discussions among participants, with remarks like “This smells amazing! Where can I buy this shampoo?” reflecting the immediate impact on consumer interest and purchasing intent.

Social media activity surged during the event, with 187 posts generated across platforms, leading to a total potential audience reach of 864,000 followers. This remarkable level of engagement was measured according to Meltwater’s analysis from January 24 to March 5, 2026, showcasing the vast influence of user-generated content (UGC) in driving brand awareness.

Why a Women's Day Collaboration with a Sauna?

Shinagawa Sauna's Women’s Day is no ordinary event; it is a highly anticipated occasion where a typically male-centric facility opens its doors to women, creating a buzz that attracts ardent participants. The environment fostered a strong desire to share experiences, making it the perfect backdrop for UGC to flourish. Moreover, the natural sequence of using shampoo and drying hair in the sauna’s facilities allowed for an organic interaction with the promoted products.

The concept revolved around two key elements: gathering passionate women at a momentous occasion and presenting them with inevitable moments of product usage. By combining these aspects, HIDANE tailored their marketing strategy to ensure a memorable and effective experience for the attendees.

Campaign Details

1. Experiential Locations (Shower and Powder Zones)

Within the shower area, HIDANE strategically placed shampoo, conditioner, and body wash. Similarly, dryers positioned in the powder zone complemented the overall experience. Participants could ensure their hair was dry post-sauna, naturally integrating product use into their routine rather than merely showcasing the products. This seamless interaction heightened the impressions of scent and cleanliness, making the encounter more impactful than typical experiences.

2. Complimentary Sample Packs

Every attendee received a complimentary sample pack consisting of shampoo, conditioner, and hair oil. By allowing participants to continue their experience at home, HIDANE successfully bridged the gap from initial engagement to purchase.

3. Online Promotion via Sauna Collection

HIDANE leveraged their sauna-centric media, “Sauna Collection,” to extend the reach of event promotions. An Instagram reel announcing the event amassed over 129,000 views and 627 likes, enhancing visibility and interaction with existing followers.
