Local Commercial Door Specialists – Your Project Partners

With the largest team of certified fire door professionals in the region, we provide:
✓ Complete commercial door system audits
✓ Fire code compliance consulting
✓ Precision installation by licensed technicians
✓ Ongoing maintenance programs

🔥 Japan Fire Door Certification: Regulatory Framework

1. Core Legislation

  • Building Standards Act (建築基準法)
    • Mandates fire doors in public/commercial buildings
    • Requires fire compartmentalization (max. 500m² per zone in high-rises)
  • Fire Service Act (消防法)
    • Specifies installation rules and maintenance protocols
    • Enforces linkage to central fire alarm systems

2. Japanese Industrial Standards (JIS)

StandardScopeKey Criteria
JIS A 1304Fire resistance testingIntegrity (E) + Insulation (I); e.g., EI 60 (60 mins @ ISO 834 curve)
JIS A 1311Fire door-specific testsSmoke leakage <3m³/h·m² at 50Pa; max. 3mm door-frame gaps
JIS A 1321Material combustibilityClass 1 (Non-combustible) or Class 2 (Quasi-non-combustible)

🔍 Fire Door Classes:

  • Class A (甲種): ≥60 mins fire resistance (mandatory for buildings >30m)
  • Class B (乙種): ≥30 mins fire resistance

⚙️ Certification Process

4-Step JIS Approval

  1. Testing
    • Conduct fire/smoke tests at accredited labs (e.g., Building Research Institute, BRI)
  2. Documentation
    • Submit technical files: Test reports, ISO 9001 FPC records, Japanese installation manuals
  3. Factory Audit
    • On-site assessment by JQA or JIS Mark certification bodies
  4. Certification
    • Grant JIS Mark with unique ID for door labeling

Ongoing Compliance

  • Annual surveillance audits + retesting every 3 years

🏙️ Sector-Specific Requirements

Building TypeAdditional Requirements
HospitalsAntibacterial coatings; zero-smoke leakage (Sa); ≥800mm clear width
High-Rises (>50m)EI 90+ doors; seismic-rated frames (JIS A 1414); central alarm integration
HotelsPanic hardware (EN 1125 / Hanedashi system); self-closing force ≤80N
Historical SitesFire-treated wood doors passing JIS A 1301 radiant ignition test

✅ Installation & Maintenance Rules

  • Labeling: Permanent JIS Mark with fire rating (e.g., “甲種60”) and manufacturer ID
  • Inspections:
    • Bi-annual functional checks (closing force, seal integrity)
    • Annual reports submitted to Fire Department (消防署)
  • Installers: Licensed Fire Equipment Technicians (消防設備士) must certify installations

⚠️ Key Compliance Challenges

ChallengeSolution
Seismic ResistanceFlexible frame connectors (tested to JIS A 1414)
High HumidityEPDM/Nitrile seals (95% RH tolerance)
DocumentationJapanese-language technical manuals

📅 2025 Regulatory Updates

  • Digital Certification: Mandatory use of JIS Mark Online Database
  • Sustainability: Public projects require EPD (ISO 14025) carbon footprint declarations
  • Penalties: Non-compliant installations face ¥1M+ fines and project suspension

🚀 Recommendations for Foreign Manufacturers

  1. Pre-certify to EN/UL: Streamlines JIS testing (60% test overlap)
  2. Partner Locally: Collaborate with Japanese agents (e.g., Mitsubishi Materials) for:
    • Documentation translation
    • Fire Department liaising
  3. Prioritize:
    • Seismic-ready designs
    • Hospital/high-rise compliant solutions
    • EPD-certified sustainable products

YK Door Industry’s Commercial Fire‑Door Solution for TOFROM Yaesu Tower (B Block), Tokyo

When Tokyo’s landmark TOFROM Yaesu Tower (B Block) called for a fire‑safety partner, YK Door Industry stepped in to deliver more than just code‑compliant doors—we delivered confidence. Nestled atop Tokyo Station, this mixed‑use podium blends high‑end retail, a boutique hotel, and Class‑A offices. Our brief was clear: supply commercial fire doors that withstand millions of footsteps, seal out smoke in pressurized corridors, and integrate seamlessly into a 5G‑driven “smart building” environment.

From the start, YK’s engineering team collaborated with the tower’s architects to pinpoint critical zones—lobby entrances, back‑of‑house corridors, and glazed retail fronts—where EI 60 fire rated doors would form the first line of defense. Recognizing Tokyo’s seismic and humidity challenges, we specified galvanized‑steel cores, intumescent seals tuned for the city’s salty winters, and Class Sa‑rated smoke barriers to ensure less than 3 m³/h·m² leakage at 50 Pa.

On the logistics front, our “pre‑hung” approach meant each door arrived factory‑fitted with C5‑rated self‑closing closers, panic‑bar hardware, and smart‑hold sensors that tie into the building’s digital management platform. YK’s local crew then executed laser‑precise gap scans—every clearance held to within 2 mm—so that when the fire‑alarm test cycle ran, each fire door snapped shut in under 0.8 seconds, just as we promised.

By project handover, YK had installed 180 doors in under eight weeks, with zero post‑inspection defects. The result: a fire‑rated door system that not only meets EN 1634‑1 and EN 16034 standards but also elevates TOFROM Yaesu Tower’s everyday functionality and luxury experience.
