Overview: Nemcaro at the GOOD LIFE Fair 2025
The wellness technology company Croix showcased its sleep-centric wellness speaker, Nemcaro, at the GOOD LIFE Fair 2025—one of Japan’s largest sustainable lifestyle events. Held at Tokyo Big Sight from September 26–28, the fair brought together innovators in mindfulness, health tech, and home wellness. Nemcaro was presented in collaboration with Relaxest, a Tokyo-based sleep-focused beauty acupuncture salon, creating a dedicated space where visitors could experience the product’s unique blend of sound and scent.
What Nemcaro Delivers: Deep Sleep through Sound and Aroma
Nemcaro is positioned as a holistic sleep solution: a wellness speaker designed to envelop a room with 360° audio while releasing natural, 100% essential-oil aromas. The core idea is to recreate a calming, nature-inspired environment that supports relaxation and sleep. A centerpiece of the experience at the fair was the use of Solfeggio frequencies, including 528 Hz, widely regarded in sound therapy as a soothing, “miracle” frequency that can help ease stress and rebalance the autonomic nervous system. The combination of immersive sound and aromatherapy aims to reduce sympathetic arousal and encourage a gentler transition to sleep.
The Booth Experience: A Green, Calming Space
Design-wise, the Nemcaro booth embraced a nature-forward aesthetic. Green and ivory tones dominated, with lush houseplants, wooden tables, and simple wooden chairs forming a tranquil enclave within the bustling exhibition hall. This space, described by attendees as welcoming and comforting, underscored the product’s promise: a soothing background that supports nightly rest and daytime recovery. The live atmosphere featured continuous soundscapes that aligned with the brand’s wellness messaging, making it easy for visitors to imagine Nemcaro in their own bedrooms.
Hands-on Listening: Four Soundscapes to Choose From
At the fair, visitors could freely sample Nemcaro’s four audio sources—Soundscape, Forest, Spa, and Ocean. Six Nemcaro devices were arranged around a wooden table, forming a circular listening setup to allow attendees to compare the different textures side by side. In addition to the audio, guests could observe how subtle aromatics complemented the sound, contributing to a fuller sense of relaxation. The ongoing crowdfunding campaign (Green Funding) runs until September 30, 2025, and fair attendees were among the first to experience how different soundscapes affected their mood and sleep readiness.
Soundscape Variants on Offer
Soundscape provides an ambient, evolving backdrop suitable for winding down after a long day. Forest offers a woodland-inspired mix with gentle rustling and birdsong to simulate a natural night, while Spa emphasizes a calm, hydro-massage-like feel; Ocean creates a coastal, breezy soundscape for relaxation. Attendees could audition all four tracks and decide which best suited their sleep goals.
<h2 Visitor Reactions: Aesthetic and Practical Appeal
Beyond its technical features, the Nemcaro experience resonated with attendees for its design and practicality. Many visitors commented that Nemcaro’s look is “cute” and would work as a stylish addition to their rooms. This blend of interior appeal with wellness functionality appears to widen the product’s appeal beyond traditional audio gear enthusiasts, reaching audiences who value home aesthetics alongside health tech benefits.
<h2 Availability Beyond the Fair
For those who wish to experience Nemcaro outside the expo, the device is available for in-person trials at Relaxest Ebisu, a sleep-centered salon in Tokyo. This makes it convenient for prospective users to explore how the 360° sound and aroma system fits into their nightly routine. Relaxest Ebisu offers a dedicated space to unwind, aligning with Nemcaro’s mission to craft a superior sleep environment.
