Packing for Japan: 9 Must-Haves You’ll Regret Forgetting

Planning your trip to Japan is exciting. You’re likely dreaming about cherry blossoms, bullet trains, sushi, and maybe even a visit to a cat café. But before you get swept up in the magic, make sure your suitcase is packed with everything you’ll truly need. While it's easy to remember the basics like clothes, passport, and toothbrush, there are some essentials that first-time travelers often forget.

Here are 9 must-have items for your Japan adventure. Forgetting any of these might not ruin your trip, but they can definitely cause some frustration.

1. Comfortable Walking Shoes

Japan is a country best explored on foot. From temple grounds and shopping streets to subway transfers and scenic gardens, you’ll be walking a lot. Having a good pair of comfortable walking shoes is a must for exploring Japan with ease. Choose shoes that you’ve already broken in and that support your feet for long days out. Avoid brand-new shoes or anything that prioritizes fashion over comfort.

2. Travel Adapter and Power Bank

Japan uses Type A and B electrical outlets, with a voltage of 100V. While this is similar to the U.S., travelers from other countries will likely need an adapter. A universal travel adapter works well and saves space in your bag. Make sure to bring a power bank along to keep your devices charged while you're out and about. Whether you're navigating train schedules or taking photos at every corner, your phone battery will drain quickly. Having backup power keeps you connected all day.

3. Reusable Water Bottle

Tap water in Japan is safe to drink, and you’ll find water fountains in many public places. Bringing a reusable water bottle not only saves you money but also helps reduce plastic waste. Many convenience stores sell bottled water, but filling up your own is cheaper and more eco-friendly. Some train stations even have water bottle refilling stations.

4. Tissues and Hand Sanitizer

One of the surprises many travelers face is the lack of soap and paper towels in public restrooms. While Japan’s toilets are famously high-tech, they don’t always come with the basics. Tuck a pocket-sized pack of tissues and a mini bottle of hand sanitizer into your bag for quick cleanups on the go. They’re light, easy to carry, and incredibly handy when you least expect it.

5. Lightweight Jacket or Layers

No matter the season, Japan’s weather can be unpredictable. Even in summer, trains, cafes, and shopping centers often blast cold air conditioning. In spring and autumn, temperatures vary throughout the day. A lightweight jacket, cardigan, or hoodie is perfect for layering and can save you from being too cold or too hot.

6. Reusable Shopping Bag

Plastic bags are no longer free in many Japanese stores. If you plan on doing any shopping at supermarkets, convenience stores, or markets, you’ll need to bring your own bag or pay extra. A foldable reusable shopping bag takes up almost no space in your backpack and can be used again and again.

7. eSIM Plan or Pocket Wi-Fi

Internet access is a huge help when traveling in Japan. You’ll need it for train directions, translations, and staying in touch. Public Wi-Fi is available, but it's not always reliable or fast. A great solution is to purchase an eSIM plan before you arrive. It lets you skip the hassle of picking up a physical SIM or renting pocket Wi-Fi. Just activate it on your phone and you’re good to go. It’s a simple solution to stay online without the hassle of bringing additional gadgets.

8. Cash and a Coin Purse

Japan is still a cash-focused society. While credit cards are becoming more common, especially in big cities, many smaller restaurants, temples, and shops only accept cash. You can easily find ATMs in locations like post offices, airports, and most 7-Eleven convenience stores across Japan. Carrying a small coin purse is also very helpful. Japan uses coins frequently, and your pockets will fill up quickly without one. Having change on hand is great for vending machines, lockers, and bus fare.

9. Basic Japanese Phrases

While major cities have signs in English and many locals are helpful, you’ll still encounter situations where a little Japanese goes a long way. Knowing a few basic phrases can improve your experience and show respect for the local culture. Learn how to say hello (konnichiwa), thank you (arigatou gozaimasu), excuse me (sumimasen), and ask simple questions. Writing down addresses in Japanese can also help when asking for directions or using taxis.

Final Thoughts

Japan is one of the most organized, clean, and safe countries to travel to, but being prepared makes a big difference. These nine must-haves aren’t just nice to have, they’ll help you travel smarter and more comfortably. From staying powered up and connected to respecting cultural habits, every item on this list serves a purpose.

Before you close your suitcase, run through this list and make sure you’re covered. With the right gear in your backpack, you’ll be ready to enjoy everything Japan has to offer without unexpected stress.

Safe travels and happy exploring!
