Top 5 Things You’ll Regret Not Bringing to Japan

We all want to make our trips special and unforgettable, right?

I’ve traveled to several countries with a spontaneous, go-with-the-flow style—minimal planning, just pack what I can think of, and off I go. It felt cool and adventurous… until I landed in places thinking, “Why didn’t I research more?”

Now older (and hopefully wiser), I’ve learned that a little preparation makes travel way more comfortable—especially in Japan, where the culture comes with a few surprises.

So whether you’re planning to sip matcha in Kyoto or get blissfully lost in Shinjuku’s neon maze, here are 5 must-have things to bring to Japan—based on real experience and a few lessons learned the hard way.

1. Cash (Especially Yen in Small Bills)

Keyword tip: “Do I need cash in Japan?” – Yes. You really do.

As I have written in another post “Things to Know Before Going to Japan”, cash is still king!

Credit cards have been becoming more common in major cities, but if you’re planning to visit temples, local restaurants, rural towns, or even some train stations, you’ll need Japanese yen—and lots of it.

Small businesses,family-runs restaurants, and street vendors often don’t accept cards, and splitting the bill with a group at a sushi place? Much easier in cash.

Why it matters:

• Some places still don’t accept cards—especially outside Tokyo and Osaka
  
• Taxis, markets, and coin lockers usually require cash
  
• IC card* machines (like Suica or PASMO) often only accept cash top-ups
  * IC cards are very helpful when you use transportation like trains or buses. For more information, you can refer to the article “IC Cards”at Japan-guide.com!

Note: Many bank ATMs now accept foreign cards, especially at convenience stores like 7-Eleven, Lawson, and Japan Post Bank. However, some smaller or rural bank ATMs may not, so it’s smart to plan ahead and carry some cash as backup.

Pro tip: Bring a coin purse. Seriously. Japan uses a lot of coins (¥1, ¥5, ¥10, ¥50, ¥100, ¥500), and your wallet will get heavy fast.

2. Pocket Wi-Fi or SIM Card – Stay Connected Anywhere

Keyword tip: “Internet access in Japan for tourists” – essential info.

Japan isn’t known for abundant free Wi-Fi, especially once you leave airports or major hotels. If you’re navigating train transfers in Tokyo, translating menus in Osaka, or uploading Mt. Fuji selfies, a stable internet connection is your best friend.

You can rent a Pocket Wi-Fi device or buy a prepaid SIM card to ensure constant access to maps, messaging apps, translations, and travel guides.

Why it matters:

• Google Maps and Japan transit Planner are life-savers for train routes
  
• Translation apps are incredibly useful in rural areas
  
• Staying connected = peace of mind
  

Pro tip: Pre-order a Pocket Wi-Fi online and pick it up at the airport. You can even return it in a mailbox when you leave! To get the best price, you should book your JR Pass Pocket Wifi before your trip.

3. Comfortable Slip-On Shoes – For All the Shoe-On, Shoe-Off Moments

Keyword tip: “Shoes to wear in Japan” – comfort meets cultural etiquette.

Japanese culture loves clean floors and cozy indoor spaces, which means you’ll be removing your shoes a lot—at temples, traditional restaurants, ryokans, and even in fitting rooms. Laced boots? Not your friend here.

Opt for comfortable, easy-to-remove slip-on shoes that you can quickly step in and out of without holding up a line or looking like you’re losing a wrestling match with your footwear.

Why it matters:

• You’ll remove shoes at many indoor spots (even some museums and castles!)
  
• Traditional tatami rooms require bare or socked feet
  
• You’ll walk a lot—so comfort is key
  

Pro tip: Pack clean socks (maybe even cute ones). In Japan, sock etiquette is a thing—holes are a no-no!

4. Reusable Trash Bag or Ziplock – Because Trash Cans Are Rare

Keyword tip: “Why are there no trash bins in Japan?” – it’s one of the most Googled questions by tourists.

You’ll notice something odd while exploring Japan: there are almost no public trash bins. This stems from a culture that values personal responsibility for waste and also from security changes after the 1995 Tokyo subway sarin attack.

What this means for you: you’ll be carrying your trash for hours unless you’re prepared.

Why it matters:

• Street food wrappers? You’ll hold them for a while.
  
• Empty drink bottles? Bring them back to your hotel.
  
• Japan is spotless—you won’t want to be that tourist.
  

Pro tip: Pack a reusable ziplock or a compact foldable trash bag in your daypack. It’s a tiny thing that makes a huge difference.

5. Basic Japanese Phrases or Translation App – Speak the Local Love Language

Keyword tip: “Do I need to speak Japanese in Japan?” – short answer: not really, but it helps.

While Japan is incredibly tourist-friendly, English isn’t spoken everywhere—especially once you leave the big cities. But don’t worry! You don’t need to be fluent. A few key Japanese phrases can go a long way in building connection and respect.

Even saying “Sumimasen” (excuse me) or “Arigatou gozaimasu” (thank you very much) can earn you big smiles.

Why it matters:

• Local hospitality increases when you try a little Japanese
  
• It can help with directions, shopping, or restaurant menus
  
• You’ll stand out—in the best way—as a respectful traveler
  

Pro tip: Download the Google Translate app and set it to Japanese ↔ English. The camera translation feature is magic for reading menus and signs.
