Country Brief: Japan
Energy Profile
| Metric | Value |
|---|---|
| Crude oil consumption | ~3.1M bbl/day (2025) |
| Crude oil imports | ~2.3M bbl/day (~95% from Middle East) |
| Domestic production | Negligible (~3K bbl/day) |
| Hormuz-dependent imports | ~1.6M bbl/day (~70% of crude imports) |
| LNG imports | ~66M tonnes/year (~6% via Hormuz) |
| Strategic reserves (government) | ~324M barrels (146 days of consumption) |
| Total reserves (government + commercial) | ~440M barrels (254 days of consumption) |
| Refining capacity | ~3.0M bbl/day |
Key Infrastructure
- ENEOS Kawasaki Refinery: 247K bbl/day. Located in Keihin industrial zone, Japan’s largest refining corridor
- ENEOS Mizushima Refinery: 350K bbl/day, largest single refinery in Japan
- Idemitsu Chiba Refinery: Major complex in Tokyo Bay area serving Kanto region demand
- Idemitsu Hokkaido Refinery: 140K bbl/day; northernmost major refining facility
- Kiire SPR Base (Kyushu): 46M+ barrels capacity, largest national stockpile site
- Shibushi SPR Base: National oil storage base; directed to prepare for release on Mar 8
- Okinawa SPR Terminal: 8M+ barrels capacity (crude and refined product storage)
- JERA LNG Terminals: Japan’s largest LNG buyer; operates Kawasaki thermal power station and multiple receiving terminals across Kanto
Key Actors
- METI (Ministry of Economy, Trade and Industry): energy policy, emergency coordination, SPR release authority
- ANRE (Agency for Natural Resources and Energy): METI sub-agency; operational control of reserve releases
- ENEOS Holdings: Japan’s largest oil refiner (1.93M bbl/day total capacity); dominant downstream player
- JERA: Japan’s largest power generator and LNG buyer; JV of TEPCO and Chubu Electric; METI’s agent for strategic buffer LNG procurement
- Idemitsu Kosan: second-largest refiner; multiple refinery and petrochemical complexes
- JOGMEC (Japan Organization for Metals and Energy Security): manages national SPR sites; upstream resource development
- INPEX: Japan’s largest upstream E&P company; operations in Abu Dhabi (ADNOC partnership), Australia (Ichthys LNG)
Crisis Exposure (Hormuz Closure, Day 40 — Ceasefire Active)
- ~70% of crude imports transit Hormuz, approximately 1.6M bbl/day at risk. Japan gets 93% of its crude via Hormuz — the highest exposure of any major economy
- Iran approved Japan-flagged Hormuz transit (Mar 21): FM Araghchi confirmed to Kyodo: “the strait is open… closed only to ships belonging to our enemies.” Japan is one of 9 countries on Iran’s selective whitelist (with China, Russia, India, Pakistan, Malaysia, Thailand, Bangladesh, Philippines)
- SPR released: 22.46M barrels. Part of IEA-coordinated 400M barrel release (Mar 11). Japan was among 6 nations in the Mar 19 coalition statement committing to Hormuz reopening
- Government reserves provide 146 days of cover; combined with commercial stocks, 254 days. Strongest buffer in Asia, but 40 days of crisis have eroded the margin
- LNG exposure limited: only ~6% of LNG imports transit Hormuz; 4M+ tonnes in storage provides adequate near-term cover
- JERA securing at least one LNG cargo (~70K tonnes) per month under strategic buffer LNG scheme
- Refinery utilization under sustained pressure as sour crude supply from Gulf remains disrupted despite whitelist access; average runs of ~2.4M bbl/day facing throughput reductions
- Ceasefire oil crash: Brent fell ~13.8% to ~$94.13 (Apr 7-8) on two-week ceasefire announcement. Significant relief for yen depreciation pressure and import costs
- But structural risks persist: Mines remain active in the Strait, P&I clubs have withdrawn, and 800+ vessels are trapped. Iran’s ceasefire terms require transit “via coordination with Armed Forces and with due consideration of technical limitations” — Japan-flagged ships may face operational delays even with whitelist status
- Dual chokepoint risk: Houthis joined the war (Mar 28) and threatened Bab el-Mandeb closure. Japan’s alternative supply via Saudi Yanbu (Red Sea) is also at risk. Houthi status under ceasefire is unclear
Structural Vulnerabilities
- Near-total import dependency for crude oil (~95% from Middle East), the most concentrated sourcing of any G7 economy
- 70% Hormuz dependency with zero pipeline bypass options; entirely seaborne supply
- Aging, shrinking refining sector. Capacity down from 4.5M to ~3.0M bbl/day over past decade as domestic demand declines
- Yen weakness amplifies oil price shocks: every $10/bbl increase costs Japan ~$8.4B annually at current import volumes. Brent’s crash to ~$94 from $110+ provides significant relief but remains ~$20/bbl above pre-crisis levels
- Industrial cascading risk: Toyota, Honda, Nippon Steel and major manufacturers dependent on stable fuel and petrochemical feedstock supply. Production disruptions propagate through global auto and electronics supply chains
- Nuclear restart pace slow, with only ~14 of 33 operable reactors restarted; continued fossil fuel dependency for power generation
- Demographic decline reduces long-term demand but does not resolve near-term crisis exposure
TankerBrief Coverage Angle
Japanese trading houses (Mitsui, Mitsubishi, Itochu), VLCC charterers on the AG-Japan route, energy-focused hedge funds, and defense analysts tracking JMSDF operations. They need: ceasefire compliance monitoring (whether Japan-flagged ships can actually transit under Iran’s “military coordination” terms), SPR drawdown tracking (22.46M bbl released; further releases?), ENEOS and Idemitsu refinery utilization rates, JERA LNG procurement shifts, yen-oil price sensitivity (Brent crash to ~$94 vs. $110+ range eases pressure), alternative crude sourcing from Russia (Sakhalin) and Southeast Asia, industrial production impact data from Toyota/Honda supply chain disruptions, and dual chokepoint risk assessment (Hormuz + Bab el-Mandeb). Japan’s 93% Hormuz dependency and whitelist status make it the most critical test case for whether the ceasefire translates into actual cargo flow restoration.
