Nishikawa to Showcase Sleep Tech Innovations at 3rd SPEXA Exhibition

Nishikawa's Debut at the 3rd SPEXA

Nishikawa Corporation, headquartered in Chuo, Tokyo, is making its debut at the 3rd SPEXA (International Space Business Exhibition), which will take place from May 27 to May 29, 2026, at Tokyo Big Sight. The company will join the joint booth "HELLO SPACE ECONOMY," led by the space transportation company ISC, alongside nine other partners, showcasing the future of space conditioning technology.

As private-sector rocket launches continue to make strides towards regular space travel, there is a growing focus on the prospect of existing businesses expanding and thriving on a cosmic scale. This transition toward a future where everyone can venture into space brings the critical challenge of ensuring optimal physical and mental conditioning, particularly the quality of sleep, which is essential for successful missions and risk management in the extreme conditions of space.

At SPEXA, Nishikawa will introduce its proven sleep tech solutions designed to optimize conditioning through sleep enhancement. The company aims to demonstrate how its advanced technology and extensive experience can serve as a healthcare infrastructure throughout the entire spectrum of space travel in the near future.

Visitors to the booth will be presented with concrete solutions showing how current ground-based services and technologies can be adapted to the space environment. Furthermore, Nishikawa will discuss the concept of a circular sleep solution, where sleep research data gathered in space can eventually be applied back to developing terrestrial products (Earth Return).

Exhibition Overview

Purpose of Participation

In the space environment, sleeping is not merely about comfort; it represents a vital risk management effort. Factors such as the disruption of circadian rhythms due to the 90-minute cycle of sunrises and sunsets, sleep disturbances caused by weightlessness, and heightened sympathetic nervous system activity from extreme closed environments hinder deep sleep and differ greatly from Earth's norms. Nishikawa aims to address these three significant sleep risks scientifically, striving to create robust support for safe and effective recovery for space travelers under challenging conditions.

Solutions Supporting Pre-Departure, During Space Stay, and Post-Return

In the Nishikawa section of the joint booth, a seamless technical approach will be presented, covering the entire process of space travel. This will include actual showcases and four special panels elaborating on:

1. Pre-Departure (Ground-Based Preparation)
Utilizing the sleep app goo-mo, users' vital and sleep data will be scored in advance to maintain optimal physical condition for space travel. Building on insights from ground-based measurements, Nishikawa will gradually explore the application of these findings into a conditioning program prior to space missions.

2. Space Stay Approach
The sensing mattress, the AIR-Connected SX, which has successfully integrated non-contact vital measurements and comfort, is at the forefront of this approach. Nishikawa will continue to research and validate its applications for use in space environments. Although data management and application are still in the conceptual stage, collaborations and validations with various companies are planned. In addition, there are efforts to establish a concierge system that maximizes rest quality by personalizing nutrition, fragrance, exercise, and sleep environments based on data input.

3. Post-Return Recovery Support (Ground-Based Rehabilitation)
Nishikawa intends to leverage advanced recovery technologies developed on Earth, such as wearable recovery gear, to support the recovery from the physical burdens accumulated during space living and gravitational changes. By enhancing sleep quality, the company aims to contribute to swift social reintegration and recovery through partnerships in the rehabilitation sector.

Key Exhibition Contents

The booth will prominently feature a bed display based on an actual mattress, allowing attendees to experience measurements via Nishikawa's unique autonomic nervous balance visualization service, Kokoromie. Participants can calibrate their physical and mental conditions with this innovative technology, along with recovery wear designed to support physical conditioning, all aimed at a futuristic vision for sleep and rest solutions.
