Japan is an easy country to travel in, but there are a few things that can make your trip much more comfortable.
The good news is that you don’t need to buy every travel gadget you see on Amazon.
Many everyday items can be bought after you arrive in Japan. On the other hand, some things—especially those related to your smartphone—are much easier to prepare before your trip.
As a Japanese dad who often travels around Japan with my family, these are the items I think are actually worth bringing.
In a Hurry? Start With These 5 Items
| Priority | Item | Recommended for |
|---|---|---|
| ⭐⭐⭐⭐⭐ | Power Bank | Almost everyone |
| ⭐⭐⭐⭐⭐ | USB Charger | Almost everyone |
| ⭐⭐⭐⭐⭐ | Comfortable Sneakers | Everyone |
| ⭐⭐⭐⭐☆ | Foldable Umbrella | Summer & Rainy Season |
| ⭐⭐⭐⭐☆ | Eco Bag | Shopping & Souvenirs |
If you only prepare these five things, you’ll avoid most of the common problems travelers face in Japan.
1. Power Bank (My #1 Recommendation)
Recommended for: Almost everyone
If I could recommend only one item for a trip to Japan, it would be a power bank.
Travelers use their phones constantly in Japan—for maps, train apps, translation, hotel reservations, photos, messaging, and sometimes Mobile Suica.
I learned this from my own experience.
One day, I spent too much time browsing the internet on the train while going out. By the time I was heading home, my phone battery had dropped below 5%.
Since I use Mobile Suica, I kept thinking,
“What if my phone dies before I get through the ticket gate?”
Instead of enjoying the trip home, I spent the whole journey watching my battery percentage.
For visitors to Japan, the situation could be even worse. Without your phone, you could lose access to Google Maps, train route apps, translation, hotel reservations, and contact with your family.
That’s why I often say:
When traveling in Japan, your battery percentage is almost as important as your passport.
This is especially important if you plan to use your iPhone at train ticket gates. Before your trip, check whether Welcome Suica Mobile works with your device and payment card.

What I would buy
I’d look for:
- Around 10,000mAh
- Built-in USB-C cable
- Around 30W charging
- Battery level display
- Compact size
A model like the Anker Nano Power Bank is where I’d start.
Who should buy one?
- First-time visitors to Japan
- People using Google Maps all day
- Travelers taking lots of photos
- Anyone relying on their phone for transportation
Downside
Larger batteries are heavier. For most travelers, around 10,000mAh is enough.

2. USB-C Fast Charger
Recommended for: Everyone
A compact USB-C charger is another item I always recommend.
If you’re charging both your phone and power bank overnight, a fast charger with two USB ports is very convenient.
What I’d choose
- USB-C
- Fast charging
- Compact size
- Foldable plug if possible
A 30W charger is enough for most travelers.
Downside
Some chargers are extremely small but only have one USB port.
Families may prefer two-port models.

3. Comfortable Sneakers
Recommended for: Everyone
This isn’t really something I encourage you to buy for this trip.
Instead, bring the most comfortable sneakers you already own.
Japan involves much more walking than many visitors expect.
Even in Tokyo or Osaka, you’ll walk long distances inside train stations and between attractions.
If you do need new shoes, make sure you’ve worn them before your trip.
4. Foldable Umbrella
Recommended for: Summer travelers and the rainy season
Japanese weather changes quickly.
A lightweight folding umbrella is much easier to carry than buying a convenience-store umbrella every time it rains.
Look for
- Lightweight
- Compact
- Easy to open
- Strong enough for daily use
You don’t need an expensive umbrella.

5. Eco Bag
Recommended for: Shopping lovers
You’ll probably buy more souvenirs than you expect.
A foldable eco bag takes almost no space and is surprisingly useful.
You can also buy one at a Japanese 100-yen shop after arriving, so this isn’t essential.
👉 Check foldable eco bags on Amazon
6. Small Trash Bags
Recommended for: Families
Public trash bins are less common than many travelers expect.
When I go out with my children, I always keep a few small plastic bags in my backpack.
They’re perfect for snack wrappers or used tissues until I find somewhere to throw them away.
You can also buy them easily at Japanese 100-yen shops.

7. Compression Packing Cubes
Recommended for: Long trips
If you’re planning to buy souvenirs, compression packing cubes help create extra luggage space.
I prefer zipper-style cubes because they don’t require a vacuum cleaner.
Remember that they reduce volume—not weight.

8. Foldable Water Bottle
Recommended for: Summer travelers
Japan’s summers are hot and humid.
A foldable water bottle is useful if you’ll be walking all day.
That said, drinks are easy to buy almost everywhere in Japan.
👉 Check collapsible water bottles on Amazon
9. Coin Purse
Recommended for: Travelers carrying cash
Japan accepts cards more than before, but coins are still useful at shrines, temples, some local shops, and older coin lockers.
If your wallet already handles coins well, you probably don’t need another one.
👉 Check compact coin purses on Amazon
10. Card Holder or Travel Wallet
Recommended for: Travelers using a physical Suica card
Keeping your Suica card somewhere easy to reach saves time at train stations.
I don’t recommend storing your passport, cash, credit cards, and transportation card in one place.
Losing everything at once is much more stressful.
👉 Check travel wallets on Amazon
Optional Travel Items
These aren’t necessary for everyone, but they may be useful depending on your trip.
AirTag
Great for people worried about lost luggage.
👉 Check Apple AirTag on Amazon
Universal Travel Adapter
Necessary if your country’s plug type is different from Japan’s.
👉 Check universal travel adapters on Amazon
Digital Luggage Scale
Useful if you expect to bring home lots of souvenirs.

Things You Probably Don’t Need to Bring
You can usually buy these after arriving in Japan:
- Large umbrellas
- Drinks
- Everyday toiletries
- Plastic bags
- Charging cables
- Eco bags
Unless it’s medication or something you personally rely on, don’t feel pressured to pack everything before your trip.
Final Thoughts
You don’t need dozens of travel gadgets to enjoy Japan.
If you’re preparing for your first trip, I’d personally start with these five items:
- Power Bank
- USB Charger
- Comfortable Sneakers
- Foldable Umbrella
- Eco Bag
Buy only what solves a real problem for your trip.
The less unnecessary gear you carry, the more you’ll enjoy exploring Japan.
