Discover 'Nemuribito': The New Sleep Mask Brand

On December 15, 2025, the Tokyo-based company, Train Co., will launch its new sleep mask brand, 'Nemuribito'. In a world where people often struggle to achieve quality sleep due to short sleep durations and digital distractions, Nemuribito aims to revolutionize the way we sleep by providing customizable solutions tailored to individual needs.

A Range of Choices for Every Sleeper

With six distinctive types of sleep masks, users can select the perfect mask based on their daily conditions and sleep goals.

1. 3-D Light Blocking Eye Mask - Priced at ¥2,640
This innovative mask features a unique 3-D structure that blocks out even the slightest light, enveloping you in a darkness comparable to a deep forest, regardless of your surroundings. The slow-recovery cushion hugs your eyes gently, and an adjustable velcro strap ensures a perfect fit.

2. Weighted Eye Mask - Priced at ¥3,190
Designed with 270 grams of natural stone beads, this mask delivers a calming weight around the eyes, promoting relaxation. The beads' mobility ensures a snug fit, enhancing its light-blocking capabilities, while the smooth rayon-blend fabric offers a comforting touch.

3. Warm Eye Mask - Priced at ¥1,980
Recognizing the benefits of warmth, this mask helps activate the parasympathetic nervous system for deeper sleep while also blocking out disruptive sounds. Crafted from soft, fleece-like material, it offers a warm embrace and generous coverage that effectively shields from light.

4. Cooling Eye Mask - Priced at ¥1,980
Made from a specially formulated cooling fabric, this mask is designed for hot nights or post-screen fatigue, providing a refreshing chill. Boasting a remarkable Q-max value of over 0.4, it retains its cooling properties even after washing. The built-in nose pad enhances light-blocking by filling gaps around the nose and cheeks.

5. Travel Eye Mask - Priced at ¥2,200
This 3-D molded design contorts to your unique facial shape, ensuring optimal light blocking. Complete with slow-recovery earplugs to dampen noise, it's perfect for refreshing power naps during travel and conveniently packs into a special pouch for easy transport.

6. Natural Silk Eye Mask - Priced at ¥2,640
Made entirely from luxurious, natural silk, this mask promotes high-quality sleep. Silk, known for its similarity to human skin, protects the delicate skin around the eyes from dryness, delivering comfort that lasts through all seasons.

The launch of 'Nemuribito' signifies a thoughtful response to the modern challenges of sleep. The brand not only focuses on efficient sleep support but also encourages users to enjoy the ritual of selecting their sleep accessory.

You can purchase these masks at the official online store Train Co. or at selected variety shops nationwide.
