New Standards for Closed-Type Sprinkler Heads Set to Enhance Fire Safety
Tokyo, Japan – July 30, 2025 – The Fire and Disaster Management Agency (FDMA) of Japan today announced the promulgation of new ministerial ordinances and amendments to existing regulations concerning fire safety standards. Among the key updates is the establishment of technical standards for closed-type sprinkler heads, a move expected to significantly bolster fire prevention and response capabilities across the nation.
The newly released “Ministerial Ordinance Establishing Technical Standards for Closed-Type Sprinkler Heads and Partial Amendment to the Fire Service Act Enforcement Regulations” (announced on July 30, 2025) follows a comprehensive public comment period, indicating a thorough review and consideration of stakeholder input. This promulgation signifies the culmination of efforts to modernize and refine fire safety measures in alignment with evolving technological advancements and the pressing need for enhanced protection in various building types.
Closed-type sprinkler heads, a critical component of active fire suppression systems, are designed to activate only when a specific temperature threshold is reached, ensuring a more targeted and efficient response to fires. The establishment of clear and stringent technical standards is vital for guaranteeing the reliability and effectiveness of these systems. This includes specifications related to their design, manufacturing, performance, and installation, ensuring they meet the highest benchmarks for fire safety.
The FDMA’s proactive approach in updating these regulations underscores its commitment to safeguarding lives and property from the devastating impact of fires. By setting precise technical criteria for closed-type sprinkler heads, the agency aims to:
- Improve System Reliability: Ensure that sprinkler systems equipped with these heads function as intended during a fire event, providing consistent and dependable suppression.
- Enhance Firefighting Efficiency: Facilitate more precise activation, minimizing water damage to unaffected areas while effectively containing and extinguishing fires.
- Promote Technological Advancement: Encourage manufacturers to develop innovative and high-performance sprinkler head technologies that meet the new regulatory requirements.
- Standardize Safety Measures: Create a uniform and robust framework for the implementation of sprinkler systems nationwide, regardless of geographical location or building type.
The public comment period, which preceded this announcement, provided an opportunity for industry professionals, fire safety experts, building owners, and the general public to offer their insights and feedback on the proposed changes. The FDMA’s careful consideration of these submissions reflects a commitment to a collaborative and transparent regulatory process.
This update to fire safety regulations is a significant step forward in Japan’s continuous efforts to build a safer society. The enhanced technical standards for closed-type sprinkler heads are expected to contribute to a reduction in fire-related incidents and their associated damages, ultimately leading to greater peace of mind for all citizens. The FDMA will continue to monitor the implementation of these new standards and adapt regulations as necessary to maintain the highest levels of fire safety.
