Dive into the World of Pokémon Sleep at Soka Health Center

Indulge in a remarkable sensory experience at the collaboration event, Soka 'Sleep' Health Center, which features a unique blend of gaming and wellness. From November 26 to December 17, 2025, enjoy an exclusive opportunity to explore aromatic loofs inspired by the vibrant worlds of Pokémon Sleep. This innovative event was brought to life through a collaboration between Pokémon Sleep, a sleep game application, and Sauna Ikitai, Japan's largest sauna portal and search app. Hosted at Yunoizumi Soka Health Center in Saitama, the event showcases two distinct aromatic loof experiences reflecting the game's immersive environments: Wakakusa Island and Cyan's Beach.

Background of the Collaboration Project

This initiative stems from a joint experimental project titled “Sa to Su”, which began in August 2025. It explores the relationship between sauna activities and sleep enhancement through immersive experiences. The Yunoizumi Soka Health Center has been transformed into the Soka Sleep Health Center to promote relaxation and restorative sleep through this unique sauna experience. Taking inspiration from the iconic locations in Pokémon Sleep, IRiS Tokyo curated distinct aromas that capture the essence of the game, transforming the sauna setting into a multi-dimensional experience.

The aromatic loof sessions will embrace the game's environments, promising visitors a relaxing journey that leads to deeper tranquility after sauna use. Attendees can expect a playful atmosphere filled with Pokémon-themed elements throughout the facility.

Findings from the “Sa to Su” Research

Recent studies conducted under the “Sa to Su” project reveal insights into how warmth and sauna experiences can improve sleep. These findings are available to the public, demonstrating the potential impacts of temperature and environmental conditions on sleep quality.

The Two Unique Aromas on Offer

1. Earth & Breath (大地と息吹) - Inspired by Wakakusa Island
This aroma encapsulates the essence of breath galbanum, intertwined with the tender notes of young grass, herbs, and warm woods. It creates a scent reminiscent of serene deep breaths taken amidst the tranquility of a forest. With the sauna's heat, the aroma gently unfolds, allowing guests to naturally align their breathing rhythms, creating a harmonious atmosphere of calmness.

2. Ocean & Glow (海と光彩) - Inspired by Cyan's Beach
This fragrance evokes the clarity and serenity of a peaceful seashore. Featuring notes of bergamot blended with light herbs, vibrant citrus, and gentle wood, it harmoniously soothes the senses much like a calming sea breeze. Immerse yourself in a smell that reflects the ebb and flow of the ocean, allowing for a tranquil experience punctuated by moments of reflective peace.
