Koala's Silver Week Sale: Refresh Your Sleep Environment

As summer transitions to autumn, the upcoming Silver Week is the perfect opportunity for a sleep reset. Koala Japan Co., Ltd., headquartered in Shibuya, Tokyo, is hosting the "Koala Silver Week Sale" until September 23, offering discounts of up to 20% on popular items like mattresses and sofa beds. If you've been feeling fatigued from summer travel or the heat, now is the time to invest in a high-performance sleep setup.

Why Is Autumn Sleep Important?

Autumn is characterized by cooler temperatures at night, creating an ideal environment for restful sleep. However, the lingering fatigue from summer and shorter daylight hours can make it challenging for many to achieve quality sleep. As the saying goes, the “long autumn nights” present a great chance to reclaim rest that might have been missed during the hectic summer. To usher in a vibrant winter season, it’s essential to reassess and improve your autumn sleep habits.

About Koala®

In Japan, where sleep deprivation is prevalent, improving "Slipa" (sleep performance) is crucial. According to the OECD, Japan has the shortest sleep durations among its 33 member countries. Founded in 2015 in Australia, Koala adopted a direct-to-consumer model for bedding and furniture. Since its expansion into Japan in 2017, Koala has been dedicated to researching and developing mattresses that enhance sleep quality.

Our efforts have garnered recognition, with our Original Koala Mattress being awarded the number one spot in both the high-resilience and low-resilience mattress categories by the comparison service MyBest in September 2024. In October, we launched the "Koala Mattress® PLUS" and "Koala Mattress® SUPREME." Furthermore, in November 2025, the Original Koala Mattress received the prestigious sleeping category Grand Prize at the MyBest Award 2025. Each product features simple, elegant designs inspired by Australia’s beautiful nature.

Under our goal to create healthier and happier living environments, Koala has donated over AUD 1.5 million to the World Wildlife Fund (WWF) to support the protection of endangered species, including koalas.
