In Japan sandwich panels by core materials is divided into EPS, mineral wool, PIR, and PU insulation are conducted within a dual framework of JIS Japanese Industrial Standards and the MLIT Ministry of Land, Infrastructure, Transport, and Tourism building regulations, which focus on earthquake safety and energy performance. According to JIS A 9511, expanded polystyrene EPS is assessed for compressive strength, heat conductivity, and stability in size. Despite its widespread use in home insulation and off-site construction due to affordability and light weight, MLIT guidelines limit its application in specific fire-rated structures, mandating protective coverings to meet fire resistance and seismic safety requirements. Mineral wool, categorized under JIS A 9504, is regarded as non-combustible and is preferred in commercial and industrial establishments where fire safety is crucial. MLIT energy regulations in line with Japan’s ZEH/NZEB initiative also acknowledge mineral wool for its sound insulation and longevity, although moisture defense is essential in Japan's humid weather. Polyisocyanurate PIR and polyurethane PU foams are governed by JIS thermal insulation regulations, with PIR being favored due to its enhanced thermal resistance and excellent fire safety, meeting MLIT's updated fire safety standards. Both PIR and PU are widely utilized in cold storage facilities, transportation centers, and modular building, as their high R-values lessen energy usage, aligning with Japan’s Energy Conservation law. Notably, MLIT mandates that all insulation systems fulfill earthquake safety standards, ensuring that panels do not separate or jeopardize structural integrity during seismic events. Current research and development in Japan has concentrated on flexible adhesives, pliable coverings, and moisture-resistant coatings to guarantee compliance in diverse climates and seismic areas. JIS and MLIT guidelines ensure that insulation materials provide a balance of heat retention, fire safety, and earthquake resilience, fostering innovation and dependability in Japan’s energy-efficient and disaster-ready construction industry.

In Japan sandwich panels by facing materials is divided into aluminum, cement board, and steel facings used in sandwich panels are evaluated according to strict JIS fire regulations and MLIT construction standards, focusing on safety in areas prone to earthquakes and high humidity. Aluminum facings fall under the JIS H 4000 series for aluminum sheets, making them lightweight, resistant to corrosion, and commonly utilized in roofing and exterior cladding for modular and industrial buildings.
