🌀 Typhoon in Japan
A practical survival guide — alerts, shelter, transport, and insurance from a Gifu interpreter
Friend A messaged me at midnight: “The hotel just announced a typhoon warning. What do I do? Should I leave?” Typhoons sound scary, but Japan is incredibly prepared. Here is your step-by-step playbook — from decoding alerts to finding shelter, rebooking flights, and handling insurance claims. Stay calm, stay safe.
🌀 Typhoon season — August to October
Typhoons are a normal part of Japanese summer and early autumn. Japan has world-class infrastructure, early warning systems, and trained staff. Panic is unnecessary; preparation is everything. The 2026 season was already active by June, with Typhoon No. 6 forcing JR Central and JR East suspensions well before the traditional August–October peak — a reminder to check conditions even outside the "expected" months.
📌 Obon Warning (Mid-August): If a typhoon hits during Obon, hotels and trains are booked solid. Do not wait at the airport — use Live Japan or Navitime to find business hotels in smaller nearby cities before they sell out.
⚠️ Decoding typhoon alerts — the 1–5 system
| Level & JMA Naming | Action Required | Japanese Term |
|---|---|---|
| Level 1 & 2 Advisory | Information only. Check the weather; travel as usual. No need to worry yet! | 早期注意情報／注意報 (Souki Chui Jouhou / Chuihou) |
| Level 3 Warning | Elderly / High-risk groups should evacuate immediately to a shelter. | ้ซ้ฝข่ ็ญ้ฟ้ฃๆ็คบ (Koresha-to Hinan Shiji) |
| Level 4 Danger Warning | Everyone in designated at-risk areas must evacuate now. | 避難指示 (Hinan Shiji) |
| Level 5 Emergency Warning | Immediate danger. Disaster has occurred. Take life-saving measures (Vertical Evacuation). | 緊急安全確保 (Kinkyu Anzen Kakuho) |
🆕 2026 update — the names got clearer: Since 29 May 2026, the JMA renamed most of its rain, flood, and landslide warnings to include the level number directly in the name itself — e.g. "Level 4 Heavy Rain Warning" or "Level 4 Landslide Urgent Warning." If a warning name has a number in it, that number is the level in the table above. The one exception that matters for typhoons: wind, blizzard, and heavy snow warnings were deliberately left out of this renaming (moving during high wind is its own danger), so you may see both an old-style wind warning and a new numbered rain warning on the same day — treat whichever is higher as the one to act on.
🧠 Interpreter’s Secret: On station screens, “運休” (Unkyu) means cancelled. “調整中” (Chosei-chu) means they are still deciding — that is your cue to find a hotel nearby immediately before they sell out. Don’t confuse it with “一部運休” (Ichibu Unkyu) though — that just means reduced service, where you might wait longer for your next train or bus.
📋 Before the typhoon — what to do
- Charge everything — phone, power bank, laptop. Aim for 100%.
- Download offline maps (Google Maps) and save your hotel’s address in Japanese.
- Stock up at a konbini — water (3L per person per day), CalorieMate, energy jellies, canned fish, inari sushi, onigiri. Bread and instant noodles vanish first.
- Withdraw cash — ¥20,000–¥30,000. Power outages can disable ATMs and credit cards.
- Take photos of your room (for insurance, in case of damage).
- Check your airline app — many issue travel waivers 24–48 hours before.
🍱 Konbini Lockdown List: Youkan (sweet bean bars), In-Jelly pouches, canned yakitori/mackerel, barley tea (Mugicha). No microwave or hot water needed.
🏠 During the typhoon — staying safe
- Stay indoors — away from windows. Keep curtains closed to catch flying glass.
- Vertical evacuation — if you are near a river or coast and cannot reach a shelter, move to the highest possible floor of a sturdy concrete building (modern hotel or school).
- Never use elevators — power outages can trap you. Use stairs only.
- Listen to hotel staff — they run drills and know the local risks.
- Do not go outside to “see the storm” — flying debris is deadly.
📦 Window Safety in Rural Areas: If you are staying in an older building or outside the city center, windows are often thinner, single-pane glass without heavy shutters. Skip taping an “X” on the glass—disaster studies show it won't stop a window from breaking and actually creates larger, more dangerous shards if it fails. Your truest shield is the fabric barrier: draw your heavy curtains or blinds tightly closed and clip them shut. If flying debris does break the thin glass, the fabric acts as a vital secondary wall to catch loose fragments inside the frame and away from you.
🚆 Transport and “Planned Suspension” (Keikaku Unkyu)
In 2026, Japan uses a “Proactive Shutdown” strategy. JR Central is conservative and usually publishes planned suspensions (計画運休, keikaku unkyu) about 24 hours before a typhoon’s peak impact — not the day of. When a Shinkansen is running, it is safe; JR would rather cancel early than let a train get caught mid-route.
- The 24-Hour Rule: If a shutdown is announced for tomorrow, leave today. Do not wait for the “last train” — it will likely be cancelled.
- Why it stops even when Gifu is sunny: The Tokaido Shinkansen operates under strict rainfall limits — if rain gauges in Shizuoka (the main mountain chokepoint on the line) register too much water, the entire Tokyo–Osaka line can halt regardless of conditions elsewhere.
- If you're flying via Kansai (KIX): The airport sits on an artificial island connected to shore by a single bridge. A severe typhoon can flood the airport island or damage the bridge access (as happened in 2018), stranding arriving and departing passengers alike — build in extra buffer time and a backup plan if your itinerary routes through KIX during a storm.
📸 Proof for insurance: Take a photo of the station screen showing “Cancelled” or obtain the Certificate of Delay (遅延証明書 — Chien Shoumeisho) from the ticket gates. Insurers require this document.
🍱 Survival — food and shelter quick guide
| Category | Top Recommendation | Jin’s Tip |
|---|---|---|
| Food | Youkan, Canned Fish, In-Jelly | Bread sells out first. Grab CalorieMate — it lasts for years. |
| Water | 3L per person per day | Mugicha (barley tea) or Pocari Sweat work too. |
| Shelter | Reinforced concrete, high floor | Use stairs only! Elevators are a trap during power outages. |
| Refunds | 100% for cancelled trains | Take a photo of the “Cancelled” sign for insurance proof. |
💰 Cash is king again: If power fails, ATMs and card terminals go down. Withdraw ¥20,000–¥30,000 before the storm hits.
⚖️ Aviation law and your rights
The Reality Check: Unlike Europe (EC 261), Aviation Law in Japan does not require airlines to pay for hotels or meals during weather-related delays (Force Majeure).
- Your Safety Net: Your travel insurance is your only source of reimbursement for extra hotel nights.
- Mandatory Doc: You must get a Kessei Shoumeisho (欠航証明書 — Cancellation Certificate) from the airline’s app or counter to file a claim.
💡 Stay connected during the storm: see the 2026 Digital Traveler Guide for the best data SIMs and emergency apps.
📄 Digital proof: Screenshot your airline’s “Flight Delay Certificate” page. Without it, many travel insurance policies will deny your claim entirely.
🔧 After the typhoon — recovery and rebooking
- Be patient — transport may take hours to resume. Staff are working as fast as possible.
- Check your airline app — rebooking is often automatic, but you may need to confirm your new flight.
- Some tourist sites may close for inspection — have indoor backup plans (museums, aquariums, shopping).
- Rural and mountain areas recover slower — a town near Takayama or Hakone might be reachable by train again while its hiking trails, cable cars, or open-air baths stay closed for safety inspection. Check the local tourism board, not just the train schedule, before you commit to a day trip.
- Monitor local news — NHK World (English live stream) is reliable and free.
⛰️ Gifu-specific tips — mountains and valleys
In rural Gifu (Shirakawa-go, Hida mountains, Gujo), the biggest risk is landslides (土石流 — dosekiryu), not wind.
- Listen to Community FM or outdoor speakers. Even if you do not understand Japanese, follow what locals do.
- Look for QR codes at bus stops — they lead to real-time digital evacuation maps for that specific area.
- If you are in a valley and water levels rise, move to higher ground immediately — do not wait for an official order.
- ⚠️ Watch out for "Senjo Kousuitai": In May 2024, the JMA began tracking these "Linear Precipitation Bands" with real-time, 2-to-3-hour advanced push alerts. If your phone or hotel staff mentions a Senjo Kousuitai hitting your area of Gifu, it means an extreme volume of rain is about to stall over your valley—treat this immediately as an urgent trigger to stay off mountain roads.

❓ Typhoon FAQ — 2026
Not necessarily. Typhoons pass quickly (often within 24 hours). If your flight is still running and your hotel is safe, you can ride it out indoors. Check your airline’s waiver policy — many allow free changes.
In short: No. Level 1 and 2 are strictly for information and preparation. They are very common during Japanese summer. Since May 2026, many of these warnings spell the level number out in their own name, which makes them easier to judge at a glance. Check the weather and your airline’s app, but you can continue sightseeing as planned. The “action” only starts at Level 3 (Elderly/High-risk evacuation).
Airlines will cancel flights if wind speeds exceed safety limits. Do not go to the airport unless your flight is confirmed — you might get stranded there if transport shuts down around you. If you're routed through Kansai (KIX), be extra cautious: its single-bridge, artificial-island setup has been cut off by severe storms before.
Landslides are the main risk. Listen to local speakers or community radio. Follow the locals. Use QR codes at bus stops for digital evacuation maps. Your ryokan will have an emergency plan — ask them when you check in.
Most comprehensive policies cover weather-related cancellations and delays, but you need proof (the airline’s delay or cancellation certificate). Always check your policy’s “natural disaster” clause. Without insurance, you pay out of pocket.
If you are in a low-lying area or near a river, move to a higher floor of a sturdy concrete building (like a modern hotel or school). Do not try to reach a public shelter if floodwaters are already rising outside.
