Scentdays, Digital Scent Streaming Service, Achieves Runner-Up at 4th Kokudozukuri Koshien

### Scentdays Claims Runner-Up at 4th Kokudozukuri Koshien

Scentdays, the scent streaming service operated by our company, has won second place at the "4th Kokudozukuri Koshien," held on June 16, 2026, at The Ritz-Carlton, Tokyo.

The competition was judged by a panel led by Toshio Tamaoka (former Air Staff Chief) as Chief Judge, with Ryuki Minamiwara serving as Deputy Chief Judge. Our company presented its ambitious vision of "digitizing scent"—a previously uncharted domain—and received high praise for its business concept.

### "Delivering Scent, Digitally." — Scentdays Tackles the Final Frontier

Music and video have long been digitized, enabling instant playback and distribution anytime, anywhere. Yet "scent" remains one of the last sensory experiences confined to physical consumption, left behind by the digital revolution.

We are tackling this final frontier. Scentdays aims to transform scent into digital data—just like MP3s for music—eliminating barriers of distance and cost. This is the world we are building.

At the heart of this experience is the smart diffuser "Scent Gem." Inspired by the CMYK four-color model used in printing, Scent Gem contains 12 base scents. By precisely controlling and blending each scent from 1% to 100%, it can theoretically generate an infinite variety of fragrance combinations.

### Key Features of Scent Gem:

- 12 Base Scents — Combine fundamental fragrances to create scents tailored to any mood or occasion

- Precise 1%–100% Output Control — Finely adjust intensity and blend ratios for nuanced scent profiles

- Integrated with Scentdays App — Select, play, and switch scents like music playlists

- Co-developed Cartridges — Developed in partnership with leading industry manufacturers, using fragrance ingredients trusted by global luxury brands and high-end hotels

Wake up to a refreshing citrus in the morning, shift to a woody scent for focus during work, and transition to soothing lavender at night. Simply choose your desired scent via the app—just like switching music playlists. Scent becomes a seamless companion throughout your day.

### The World Scentdays Aims to Create

Our mission is to "digitize scent as data, eliminate distance and cost barriers, and deliver fragrance universally." We envision a world where anyone, anywhere, can freely access and enjoy scent.

The runner-up achievement at the 4th Kokudozukuri Koshien, along with overwhelming support from our crowdfunding campaign, serves as a powerful momentum toward realizing this vision. Moving forward, we will continue to cultivate the culture of scent streaming together with more people.
