Mega Earthquake Advisory Unchanged Tourists to Japan Changing Plan
Mega Earthquake Advisory Unchanged: Tourists to Japan Changing Plans
Overview
In this urgent update filmed at Tokyo Station, John Daub addresses the widespread concern surrounding the Nankai Trough megaquake advisory issued in early August 2024. With misinformation spreading rapidly on social media, John clarifies the actual status of the advisory, noting that the Japan Meteorological Agency (JMA) and NHK report no changes in seismic activity. He contextualizes the advisory alongside other summer risks like heat stroke and typhoons, emphasizing that while residents should prepare, tourists generally do not need to cancel trips.
John breaks down the science behind the advisory, explaining it was triggered by a slow slip event and a magnitude 7 earthquake in Miyazaki, not a prediction of an imminent catastrophe. He shares practical advice for travelers, suggesting alternative destinations like Hokkaido or Tohoku for those uneasy about western Japan, while reassuring viewers that Japan's infrastructure is among the best in the world. The video also features a conversation with a guest, Max, who compares the situation to living in earthquake-prone Northern California, reinforcing the message of preparedness over panic.

Japan Travel Tips
- Monitor Official Sources: Use the NHK World app or website and the Japan Meteorological Agency (JMA) for earthquake info. Avoid social media rumors.
- JNTO Support: Call the JNTO Safe Travel hotline (050-3816-2787) for 24-hour support in English, Chinese, and Korean.
- Alter vs. Cancel: If uneasy about the Nankai Trough zone (Osaka, Kyoto, Wakayama, etc.), consider visiting Hokkaido, Tohoku, or western Japan areas like Yonago instead of canceling entirely.
- Disaster Prep: Tourists don't need resident-level kits, but know your hotel's evacuation route and keep a charged phone.
- Heat Safety: August brings heat stroke advisories across Pacific Honshu. Drink water constantly and avoid midday sun.
- Earthquake Etiquette: If shaking occurs, duck, cover, and hold under a table. Do not run outside during strong shaking.
Japanese Language & Culture Notes
- Nankai Trough (南海トラフ): A subduction zone off the Pacific coast of Japan where seismic activity is closely monitored.
- Shindo (震度): The Japanese seismic intensity scale (0-7) used to describe local shaking strength, different from magnitude.
- Advisory System: The "Megaquake Advisory" is a specific warning level introduced after 2011, triggered by statistical probability increases, not definite predictions.
- Resident Preparedness: Japanese residents keep bousai goods (disaster goods) like water, rice, and radios ready. This is standard culture, not panic.
- Infrastructure: Modern buildings, especially in Tokyo (like Tokyo Station), are retrofitted for seismic resilience.

- Travelers can adjust itineraries for comfort but canceling trips entirely is generally unnecessary.
Notable Quotes
- 00:01:32 "It's not a prediction—despite comments saying otherwise. There's higher risk within 7 to 10 days after Miyazaki, based on seismic data from sensors nationwide."
- 00:03:24 "Nothing wrong with altering plans—go to Hokkaido (cooler, no street-watering), western Japan like Yonago, or Tohoku."
- 00:04:55 "Tokyo Station's buildings are world-best, renovated 1912 facade earthquake-proofed. No city is perfectly prepared, but Japan handles it best."
- 00:10:15 "Uncertainty sparks questions—get info from sources like JNTO's Safe Travel site/hotline."
- 00:21:26 "Japan safest country—no violent crime, low rip-offs, clean, delicious food. Don't cancel over advisory."
- 00:31:53 "Point of discussions: take seriously, prep as tourist—they happen anytime. You've felt mediums? Common sense: don't panic, duck/cover/hold under table/bathtub."

Full Transcript
00:00:01 John Daub: Greetings from Tokyo Station. I'm now walking on water. There's a heat stroke advisory for many prefectures in Japan. It's not just the megaquake, which is one of the dangers of being in Japan in the summer. We also have heat stroke. We also have typhoons—one rolling through Tohoku right now. Number seven is projected to come next week near the Tokyo area. So there's a lot going on weather-wise, but it's this Nankai Trough megaquake advisory that's dominating.
00:00:31 John Daub: I've been getting so much feedback and comments—a lot wrong, some corrections, and growing misinformation. I don't want to propagate that, so it's important to look at this today. We'll check better sources tomorrow. The Nankai Trough megaquake advisory continues, announced about five days ago. NHK reports it remains unchanged. No changes in seismic activity observed—that's today's update from NHK, the government broadcaster and most authoritative source alongside the Japan Meteorological Agency (JMA).
00:01:32 John Daub: We're all living on pins and needles, but we've prepared: charged batteries in earthquake kits, extra water stocked. Should supply chains be cut, residents are ready anyway—this is just a reminder. The advisory was automatically triggered by a slow slip event with the Nankai Trough and the Miyazaki magnitude 7 earthquake. It's not a prediction—despite comments saying otherwise. There's higher risk within 7 to 10 days after Miyazaki, based on seismic data from sensors nationwide. Since then, 26 microquakes (magnitude 1 to 5) have relieved stress—NHK has the article. I hope it doesn't happen, but you can't predict earthquakes. Claims of predictions are misinformation, like August 14th rumors. Relax, don't cancel trips.
00:03:24 John Daub: A TikTok from our Discord showed a Welsh-Swedish couple altering their Japan trip—not canceling, but skipping Osaka and impacted areas. I've gotten emails from Instagram, Discord, Patreon asking what to do. Nothing wrong with altering plans—go to Hokkaido (cooler, no street-watering), western Japan like Yonago, or Tohoku (typhoon aside). Lots of safe spots outside the advisory zone. I don't blame cancellations, but big earthquakes are rare. More chance nothing happens. The advisory's for residents like me with go-kits.
00:04:55 John Daub: Tokyo's not in the Nankai Trough advisory, but there's a 70-80% chance of a Kanto megaquake in 30 years (now 20). My wife got a 5kg rice bag, water jugs, charged radio batteries—basics just in case. Her spider senses tingle despite Tokyo not being advisory-listed; it makes sense for residents to prepare. Tourists, that's not for you. Green areas on maps are impacted zones taking measures—Osaka included—but doesn't mean a quake hits. Relax, don't cancel trips. Odds are small. Tokyo Station's buildings are world-best, renovated 1912 facade earthquake-proofed. No city is perfectly prepared, but Japan handles it best. I've been through them—not worried. Post-311 upgrades everywhere.
00:07:15 John Daub: Some call it sensationalized, clickbait, fear-mongering. Japanese government warned on Nankai Trough—not Tokyo primarily, but we prep anyway. Chance of magnitude 8-9 up just 0.5%? We listen to advisories. Government psychosis? People worry, news skepticism valid. Coming in September? Don't worry. Avoid trains/bridges/Fuji? Good advice, but Fuji might be in warning anyway—tough climb regardless. Elevated Tokyo risk exists; I live in Chuo Ward near Tokyo Bay—wife wants out over land fears. Understandable—we'll move soon. Stop, drop, think about trips—don't cancel. Quakes can hit anytime; I've seen strong ones in 26 years here. Same as California (yesterday's LA magnitude 4).
00:10:15 John Daub: Uncertainty sparks questions—get info from sources like JNTO's Safe Travel site/hotline (050-3816-2787, 24-hour English/Chinese/Korean support). Heat stroke advisory blankets Pacific Honshu—Fukushima to Yamaguchi. Freaking hot; drink water. NHK World app/YouTube for authoritative updates. Recent Miyazaki aftershock (magnitude 4, Shindo 3)—expected, plate moving good. Government advice: secure furniture, check evac sites, family plans, special needs evacuate quick. Hotels guide tourists to shelters if needed.
00:14:19 John Daub: Geographer commenter: info sound, effects beyond Nankai Trough—Sagami Trough, Fuji pressure (Hakone data). Spring trip fine—useful prep video thanks. Tourists canceling? Rare event, elevated risk only. JMA auto-advisory post-2011 Tohoku parallels (slow slip + M7.1 before M9). First-of-kind, media fresh on it—concerns without scaring off travel. Earthquakes anywhere: Tottori, Niigata, Kumamoto, Miyazaki, Hokkaido.
00:21:26 John Daub: Japan safest country—no violent crime, low rip-offs, clean, delicious food. Don't cancel over advisory—avoid Mie/Wakayama/Kochi short-term maybe. Listen to geologists/seismologists via JMA/JNTO/PMO/NHK/US Embassy apps. Foreign media misunderstands Nankai Trough—use Japan English sources (huge improvement in 25 years). Warning continues; no more videos till lifted. Not fearmongering—be prepared regardless. Watch my 2M-view Tokyo Fire Dept video: duck/cover/hold under table—even weak quakes can intensify.
00:24:42 John Daub: Mom experienced Shindo 5—stayed calm to calm her. First-timers panic naturally. East vs. west Japan: east convenient via Shinkansen, west more driving/car culture. TV homogenized dialects post-WWII; regional food/sake/shochu/seasonality fun. Hospitality similar. Advisory not for tourists—prep like NYC mugging risk. TikTokers altering plans smart for comfort; Kyoto/Osaka shaking possible but infrastructure solid.
00:28:00 John Daub: Studied geology—Earth time scales immense. Fun class with storm chaser Mike Bettis. Tie-up: 2M-view Fire Dept video key. Quakes minimized here (even Noto). Tokyo/modern cities resilient—reconsider cancellations informedly.
00:30:20 John Daub: How you doing? Found me on screen? Just from inside—no sweat? First Tokyo August? Brutal—slow-baking convection oven. Did Chubu (Tateyama Alpine Route, Kamikochi), Akita festivals (Nebuta, Kanto, Kanto Kawara)—cooler north.
00:31:14 Max: Megaquake? Watched some—just be prepared. From Northern California, San Andreas Fault—earthquakes constant. Like flying: ready, but no massive plan changes.
00:31:53 John Daub: Point of discussions: take seriously, prep as tourist—they happen anytime. You've felt mediums? Common sense: don't panic, duck/cover/hold under table/bathtub. Keep head, get low if shaking hard. Thanks, Max.
00:32:55 John Daub: Thanks for watching—questions in comments. Main channel Fire Dept video comforts/preps best. See you.
