Typhoon Season in Japan: Home Preparation and Safety Tips for Expats
Discover how to protect your home and family during Japan’s typhoon season. From assembling the perfect emergency kit to securing your balcony and understanding evacuation alerts, this comprehensive guide provides essential, easy-to-follow safety tips for expats living in Japan.
Welcome to Japan’s Typhoon Season
Living in Japan offers an incredible experience, from the cherry blossoms of spring to the vibrant energy of its cities. However, part of adapting to life here means understanding and respecting nature. If you have recently moved to Japan, you might have heard the locals talking about “Typhoon Season.” While the word might sound intimidating, there is no need to panic. With the right knowledge and a little bit of preparation, you can keep your home safe and your mind at ease.
Typhoons are strong tropical cyclones that typically occur between June and October, with the peak activity often hitting in August and September. Unlike sudden earthquakes, typhoons give us warning. We usually know days in advance when a storm is approaching. This allows us ample time to prepare. The key is not to fear the storm, but to respect it by getting your home ready. By taking proactive steps, you are not just protecting your property; you are ensuring the safety and comfort of your family. Let’s dive into how you can turn your home into a safe haven during the stormy season.
Understanding the Timing and Impact
Before we start moving furniture or buying supplies, it is helpful to understand what a typhoon actually brings. In Japan, typhoons are numbered rather than named (though they have international names as well). For example, you will hear news about “Typhoon No. 19.” These storms bring heavy rain and very strong winds.
For expats, the most surprising element is often the amount of rain that can fall in a short period. This can lead to swollen rivers and localized flooding. However, modern Japanese infrastructure is built to handle significant weather events. The drainage systems in cities like Tokyo and Osaka are engineering marvels. Still, staying informed is your first line of defense. Knowing the typical patterns helps you plan your week and avoid unnecessary travel when a storm is near.
When you understand the rhythm of the season, you can plan your activities better. You might want to reschedule that camping trip or ensure your electric vehicle charging routine is adjusted so you have a full battery before the wind picks up. Being in sync with the weather is a big part of feeling at home in Japan.

Secure Your Balcony: The First Line of Defense
If you live in an apartment or a mansion in Japan, your balcony is one of the most critical areas to check. Japanese balconies are often used for drying laundry and storing miscellaneous items. However, during a typhoon, anything not secured can become a dangerous flying object.
The “Flying Object” Rule
The wind speed during a major typhoon can be strong enough to lift heavy objects. It is vital to clear your balcony of anything that isn’t bolted down. This includes:
- Laundry Poles: This is the most common hazard. Take your laundry poles down from their high hooks and lay them flat on the floor. If possible, tie them together so they don’t roll around.
- Potted Plants: Move small plants inside. For larger, heavy pots, move them close to the wall and group them together to increase stability.
- Plastic Hangers and Pegs: These can easily shatter or blow away. Bring them inside.
- Outdoor Furniture: If you have chairs or tables on your terrace, bring them indoors or secure them tightly with strong ropes.
By clearing your balcony, you are also protecting your glass windows. Many broken windows during typhoons are caused by an object from the resident’s own balcony crashing into the glass. A clear balcony means a safer living room. Additionally, ensure your balcony drains are clear of leaves and dirt. Heavy rain needs a place to go, and a clogged drain can cause water to pool and potentially leak into your apartment. Checking your drains is a simple home maintenance task that saves you from water damage.
Window Protection: Shutters and Myths
You might have noticed that many houses and apartments in Japan come equipped with metal shutters on the windows (called amado). These are not just for privacy; they are your best protection against typhoons.
Using Rain Shutters Effectively
If your home has shutters, close them as soon as the wind starts to pick up. They protect the glass from flying debris and reduce the noise of the wind, helping you sleep better during the storm. If you do not have shutters, don’t worry. Modern Japanese glass is quite strong.
The Tape Myth
You may see people taping their windows with an “X” or a grid pattern using curing tape. There is a debate about whether this actually strengthens the glass. The consensus among experts is that tape does not prevent the glass from breaking. However, it might prevent the glass from shattering into tiny, dangerous pieces if it does break.
If you choose to tape your windows, use “curing tape” (known as yojo tape in Japan), which is usually green or semi-transparent. It is designed to be peeled off easily without leaving a sticky residue. Do not use standard duct tape, as it will be a nightmare to clean later. A better alternative to tape is closing your curtains and blinds. If the glass breaks, the curtains will act as a net to catch the shards. This is a simple interior safety measure that everyone can do.
The Essential Emergency Kit (Bousai Bag)
Japan is a country prepared for natural disasters, and every household should have an emergency kit, known as a “Bousai Bag.” While this is often discussed in the context of earthquakes, it is equally important for typhoons. If the power goes out or you need to evacuate, this bag will be your lifeline.
You can buy pre-made kits at home centers or online, but customizing one for your family is often better. Here is a breakdown of what you should include.
Your Survival Checklist
| Category | Essential Items | Notes |
|---|---|---|
| Sustenance | Water (2L per person/day), Canned food, Energy bars, Vitamin jelly | Check expiration dates annually. |
| Light & Power | Flashlights, Extra batteries, Mobile battery (Power bank), Headlamp | A fully charged power bank is crucial. |
| Hygiene | Wet wipes, Portable toilet bags, Toothbrush, Feminine products | Keeping clean boosts morale. |
| Medical | First aid kit, Prescription medicines, Pain relievers, Band-aids | Keep a copy of your prescription (Okusuri Techo). |
| Documents | Copies of Zairyu Card (Residence Card), Passport, Cash (Small bills) | ATMs may not work during power outages. |
| Comfort | Warm blanket, Raincoat, sturdy gloves, Slippers | Slippers protect feet from debris. |
Having this bag ready near your entrance gives you a tremendous sense of security. You might also want to consider adding items specific to your lifestyle, such as pet food or baby supplies. If you are interested in more advanced gear, look into sustainable tech gadgets that can charge via solar power, adding an extra layer of resilience to your kit.

Power and Water: managing Utilities
Typhoons can sometimes cause power outages (blackouts) or water supply interruptions. Preparing for this scenario is straightforward and ensures you remain comfortable even if the grid goes down for a few hours.
The Bathtub Strategy
One classic tip in Japan is to fill your bathtub with water before the storm hits. This water is not for drinking, but for flushing the toilet. If the water supply stops, you can use a bucket to pour this water into the toilet tank to flush it. It is a simple backup plan that solves a major sanitation problem.
Charging Everything
Before the storm arrives, charge all your electronic devices. This includes:
- Smartphones and tablets
- Laptops
- Portable power banks
- Wireless earphones (useful for listening to news without disturbing others)
- Portable fans (if it is summer and the AC goes off)
If you own an Electric Vehicle (EV), ensure it is fully charged. Some modern EVs have a “V2L” (Vehicle to Load) feature that allows you to use the car’s battery to power home appliances. This is a brilliant application of electric vehicles in daily life, turning your car into a giant backup battery for your home.
Fridge Management
Turn your refrigerator to the coldest setting before the storm. If the power goes out, the colder temperature will keep your food fresh for longer. Once the power is out, try to open the fridge door as little as possible. A full freezer keeps cold better than an empty one, so filling empty spaces with water bottles (to freeze into ice) is a smart energy saving trick.
Information is Power: Apps and Alerts
Language barriers can be a concern during an emergency, but technology has bridged that gap significantly. You do not need to be fluent in Japanese to stay safe. There are fantastic resources available in English.
Essential Apps
- NERV Disaster Prevention: This is arguably the best app for disaster information in Japan. It provides real-time updates on typhoons, earthquakes, and floods in English. The interface is intuitive and accessible.
- NHK World-Japan: The national broadcaster provides excellent news coverage in multiple languages. Their app is a reliable source for official government announcements.
- Safety Tips: Developed by the Japan Tourism Agency, this app pushes alerts to your phone in English and other languages.
Understanding Warning Levels
Japanese authorities use a 5-level warning system. Understanding these numbers is critical for making quick decisions.
- Level 1 & 2: Advisory. stay informed and check the weather.
- Level 3: Elderly people and those with disabilities should evacuate. Others should prepare to move.
- Level 4: Everyone Evacuate. This is the critical instruction. Do not wait for Level 5. Move to a safe place or a designated shelter.
- Level 5: Emergency Safety Measures. The disaster is already happening (e.g., the river has flooded). It is too late to move to a shelter safely. You must save your life by moving to the safest part of your building (vertical evacuation).
Knowing the difference between Level 3 and Level 4 can save lives. It is also wise to check your local Hazard Map online. This map shows which areas are prone to flooding or landslides. Understanding your neighborhood’s geography is a key part of sustainable urban living.

Food Preparation: The “Typhoon Feast”
Being stuck at home doesn’t have to be miserable. In fact, many people in Japan treat it as a cozy time to relax, provided they are safe. Stocking up on food is essential, but avoid the panic buying at the last minute.
What to Buy
Focus on foods that do not require cooking, in case the gas or electricity shuts off.
- Bread and pastries
- Canned tuna, corn, and fruits
- Crackers and snacks
- Bottled tea and water
- Instant noodles (requires hot water, so keep a thermos of hot water ready)
Avoid buying too much fresh meat or fish that will spoil quickly if the fridge loses power. Instead, look for shelf-stable items. Preparing a “Typhoon Menu” can actually be fun for kids and helps distract them from the scary wind noises outside. It’s a good moment to think about smart food storage solutions for your kitchen.

Evacuation: When and Where?
Most people in sturdy concrete buildings (condominiums) will be safer staying at home than going to a shelter, provided they are not in a flood-prone ground floor unit. This is called “sheltering in place.” It is comfortable and private.
However, if you live in an older wooden house, near a river, or near a steep cliff (risk of landslides), evacuation might be necessary. Locate your nearest evacuation center (usually a local school or community center) before the storm. Walk there on a sunny day so you know the route.
If you go to a shelter, remember that it is a communal space. You need to bring your own food, water, and slippers. Pets are often allowed but must be in a cage. Checking the pet policy of your local shelter in advance is vital for pet owners in Japan.
After the Storm: Safety Checks
Once the typhoon passes, the sky often turns beautifully clear and blue. This is called “Typhoon Ikka” (Typhoon family passed). But before you rush out, do a quick safety check.
Inspect Your Home
- Balcony: Check for any debris that might have flown in.
- Windows: Inspect for cracks.
- Bicycles: If you have a bike in the parking area, check if it has fallen over.
- Solar Panels: If you have a solar system installed, do a visual check from the ground to ensure no panels are loose. Maintaining your system is crucial for long-term solar energy efficiency.
Insurance Claims
If you do suffer damage, take photos immediately. Document everything before cleaning up. In Japan, fire insurance (Kasai Hoken) usually covers typhoon damage. Contact your insurance agent or the management company of your building. They are used to handling these claims and will guide you through the process. Understanding your policy is a key aspect of financial planning for expats.
Staying Positive and Resilient
Experiencing your first major typhoon can be nerve-wracking. The wind can be loud, and the rain intense. However, remember that Japanese buildings are some of the toughest in the world. They are designed to withstand these forces.
Use the time indoors to disconnect from the busy pace of life. Read a book, play board games with your family, or catch up on sleep. If you have prepared according to these tips, there is very little to worry about. You have your water, your food, your safe zone, and your information sources.
By embracing preparedness, you transform a potential disaster into a manageable event. You are not just surviving; you are thriving and adapting to your new life in Japan. This resilience is at the heart of living sustainably and happily in a foreign country.
Conclusion
Typhoon season is just another season in the rich tapestry of life in Japan. It reminds us of nature’s power but also of the strength of community and preparation. By following these steps—securing your home, stocking your emergency kit, and staying informed—you can face any storm with confidence. Stay safe, stay dry, and enjoy the peace of mind that comes with being truly prepared.
