Universal Design for Advancing All People’s Comfort in Air Travel

Concept Development of an Inclusive Aircraft Lavatory

The Japan Aerospace Exploration Agency (JAXA), together with JAMCO Corporation and Panasonic Electric Works Co., Ltd., has launched a new collaborative initiative to develop an inclusive aircraft lavatory concept that can be used comfortably by all passengers.

To date, JAXA and JAMCO have collaborated on the Metamorphic Lavatory, an innovative aircraft lavatory concept designed to maximize the efficient use of cabin space while allowing the lavatory to be temporarily transformed into a larger, more accessible space when needed. The concept has received strong support from a wide range of stakeholders, particularly wheelchair users. While the Metamorphic Lavatory was primarily focused on addressing the needs of wheelchair users, creating a truly inclusive lavatory environment requires consideration of the diverse needs of passengers, including those with visual impairments and developmental disabilities.

With the participation of Panasonic Electric Works Co., Ltd., which has expertise in aircraft lighting and ambient design, the newly launched initiative by the three organizations aims to further enhance the accessibility and practicality of the Metamorphic Lavatory concept. By reimagining the aircraft lavatory not merely as a functional sanitation facility, but as a comfortable and thoughtfully designed space, this joint initiative seeks to develop a more accessible lavatory concept that can be used comfortably by all passengers.
