What to Pack for Japan With Kids

We Packed Wrong for Japan the First Time. Here’s What Actually Matters.

Our first trip to Japan with kids, we showed up with two massive suitcases, lace-up hiking boots, a portable car seat, and three guidebooks. Within 48 hours we’d abandoned the car seat at the hotel, bought slip-on shoes at a Uniqlo, and hadn’t opened a single guidebook. Lesson learned the hard way.

Japan is one of the most family-friendly countries on the planet, but it rewards a specific kind of packing. Light. Practical. Flexible. The stuff you think you need? You probably don’t. The stuff you’d never think to bring? That’s what saves you. After multiple trips with kids ranging from toddler to ten, we’ve dialed in our packing list to exactly what works — and ruthlessly cut everything that doesn’t.

Here’s the real list. No filler. No “don’t forget your passport” nonsense.

Shoes: The Single Most Important Thing You’ll Pack

This is not an exaggeration. Shoes will make or break your Japan trip with kids.

You take your shoes off constantly in Japan. Temples. Restaurants. Ryokans. Some museums. Fitting rooms. Friends’ homes if you’re lucky enough to visit one. Hotel rooms. The entrance to certain castles. It never stops. Every single time, you’re standing in a genkan (entryway) wrestling footwear on and off while a line of patient Japanese visitors waits behind you.

Lace-up shoes are a disaster here. Full stop. Every adult needs slip-on walking shoes, and every kid does too. We like Allbirds or Merrell slip-ons for adults and easy-on sneakers with elastic laces for the kids. Velcro works fine for younger ones. Just nothing that requires sitting down and fiddling with knots twenty times a day.

Comfort matters enormously too. You will walk more than you think. We averaged 15,000 to 25,000 steps daily — and that’s with kids who needed breaks, snack stops, and the occasional bribe. Those steps add up fast on cobblestone temple paths, Tokyo station corridors, and Kyoto hillsides. Bring shoes that are already broken in. Japan is not the place to debut new footwear.

One pair of good walking slip-ons per person. That’s it. Maybe sandals if you’re going in summer. Done.

Clothing: Pack for the Season, Not for Fashion

Japan has four distinct seasons and they’re no joke. What you pack in April looks nothing like what you pack in August. Get this wrong and you’ll be uncomfortable the entire trip.

Spring (March through May): Layers. Mornings start cool, afternoons warm up, evenings drop again. A light jacket over a t-shirt works for most days. Early March can still feel like winter in northern areas, and late May edges toward summer heat. Pack a mix and plan to adjust daily.

Summer (June through August): Brutal. Genuinely oppressive humidity, especially July and August. Pack the lightest, most breathable clothing you own. Cotton and linen. Hats for every family member — non-negotiable. High-SPF sunscreen, though you can buy excellent Japanese sunscreen there too (and honestly, the Japanese brands are better than what we get at home). Pick up a tenugui towel at any 100-yen shop once you arrive. These thin cotton towels are a lifesaver for wiping sweat, cooling down with water, and drying hands. Japanese people carry them everywhere in summer for good reason.

Autumn (September through November): Similar to spring. Layers again. October is arguably the most comfortable month to visit. Light jacket, maybe a sweater for evenings. Nothing heavy until late November.

Winter (December through February): Cold. Not Midwest-cold, but a damp, penetrating cold that gets into your bones. Bring a proper coat. Warm layers underneath. Hats and gloves for the kids. If you’re heading north to places like Sapporo or Takayama, expect snow and pack accordingly.

One dress code note: some temples require covered shoulders and knees. This isn’t universal, but it comes up enough that you should plan for it. A light cardigan or shawl that rolls into a day bag handles this. We learned after being turned away from a temple entrance in Kyoto with our daughter in a tank top. Not a fun moment.

Luggage Forwarding: The Best Thing About Traveling in Japan That Nobody Tells You

Takkyubin. Remember that word. It will change how you travel.

Japan has a courier luggage forwarding service that lets you ship your suitcases from one hotel to the next. You hand your bags to the hotel front desk in the morning, fill out a simple form, and your luggage arrives at your next hotel by the following day. It costs roughly 2,000 yen per bag (about $13 to $15 USD), and it works flawlessly.

This means you travel between cities with just a day bag. Your kids carry their own small backpacks. No dragging suitcases through packed train stations, no fighting with overhead luggage racks on the Shinkansen, no sweating through Kyoto Station with a stroller in one hand and a rolling bag in the other.

You can ship from any hotel front desk or any convenience store (7-Eleven, Lawson, FamilyMart — they all do it). Yamato Transport runs the most popular service, and their black cat logo is everywhere. The hotel staff will help you fill out the shipping label. It’s that simple.

For families, this is a game changer. An absolute game changer. We ship our big bags ahead on every travel day now and just carry day packs. The kids are happier, we’re faster through stations, and the whole day feels lighter. Budget for it. Worth every yen.

Electronics: The Non-Negotiable Tech

Pocket WiFi or eSIM. You need internet access in Japan. Google Maps is how you navigate. Translation apps are how you read menus. Train apps are how you figure out which platform to stand on at 6:47 AM in Shinjuku Station. A pocket WiFi rental (pick up at the airport) gives the whole family coverage on one device. Or grab an eSIM before you leave if your phone supports it — Ubigi and Airalo both work well. Do not rely on free public WiFi. It’s spotty and unreliable.

Universal power adapter. Japan uses Type A plugs (same as the US) but the voltage is 100V. Most modern phone and laptop chargers handle this fine. If you’re bringing anything with a three-prong plug, you’ll need an adapter because Japanese outlets are two-prong.

Portable battery pack. You’ll burn through phone battery fast between maps, photos, translation apps, and the kids watching videos during downtime. Bring at least one good 20,000mAh power bank. Two if you have older kids with their own devices.

Tablets loaded with content. Download shows and movies before you leave. Long flights to Japan need entertainment, and so do three-hour Shinkansen rides when the novelty of watching the countryside blur past wears off after twenty minutes. Pre-download everything. Don’t count on streaming.

For Toddlers: Less Than You Think

If you’re bringing a toddler to Japan, you need two things for getting around: a lightweight stroller and a baby carrier. Not one or the other. Both.

The stroller handles long walking days and gives your toddler a place to nap. The carrier handles stairs, temples, crowded trains, and any situation where a stroller becomes a liability — which happens more often than you’d expect. We used our carrier at Fushimi Inari (stairs everywhere), in packed rush-hour trains, and through narrow Kyoto alleyways where the stroller simply didn’t fit.

Diapers? Don’t overpack them. Japanese convenience stores and drugstores sell diapers everywhere, and the Japanese brands (Merries, Moony, GOO.N) are genuinely superior to what we buy at home. Softer, more absorbent, better fit. Bring enough for your first day or two and then buy locally. Same goes for baby wipes.

What you should bring from home: a few familiar snacks. Goldfish crackers, granola bars, whatever your toddler reliably eats when they’re tired and melting down. Japanese convenience stores have plenty of kid-friendly food, but in a crisis moment you want something familiar, not an experiment. A couple of small, quiet toys for trains round out the toddler kit. Sticker books were our secret weapon.

A Reusable Water Bottle for Every Family Member

Japan has vending machines on practically every block. We’re not exaggerating — there are over five million of them across the country. Drinks cost 100 to 160 yen each. Multiply that by a family of four, several times a day, for two weeks? The plastic waste and the cost both add up fast.

Bring a reusable water bottle for every person in the family. Many train stations and parks have water fountains for refills. Hotels always have them. The tap water in Japan is clean and safe to drink everywhere. A collapsible bottle works well if you’re tight on space — it flattens when empty and takes up almost nothing in a day bag.

Cash and Cards: Japan Is Still a Cash Country

Japan has changed a lot in recent years, and credit cards are accepted at more places than before. But plenty of smaller restaurants, temple entrance fees, vending machines, market stalls, and some train ticket machines still only take cash. You’ll need yen on you at all times.

Don’t bother exchanging currency at home. The rates are terrible. Instead, withdraw yen from 7-Eleven ATMs when you arrive. They accept international cards, the interface has English, and the fees are reasonable. Withdraw enough to last a few days at a time.

Get an IC card (Suica or PASMO) for every family member at the airport or any major train station. These rechargeable transit cards work on trains, buses, and most convenience stores. Tap and go. Kids under 6 ride free on most transit, but ages 6 to 11 need a child IC card at half-fare. Load them up with a few thousand yen and top off as needed. Saves you from buying individual tickets at machines for every single ride, which with kids in tow is a sanity-saving move.

What NOT to Pack (Seriously, Leave It Home)

Too many clothes. Nearly every hotel in Japan has a coin laundry, and many have it right on-site. Laundromats are everywhere in cities too. Pack five days’ worth of clothes and wash mid-trip. We do laundry every three or four days and it takes an hour. This alone cuts your luggage in half.

Towels. Every hotel provides them. Ryokans provide them. Many public baths provide them or rent them for 200 yen. You do not need to bring towels from home.

A car seat. You almost certainly don’t need a car in Japan. The train system is so thorough and efficient that driving is actually slower and more stressful in most areas families visit. We’ve done Tokyo, Kyoto, Osaka, Hiroshima, Hakone, and Nara entirely by train. Leave the car seat at home.

Guidebooks. Heavy, outdated the moment they’re printed, and redundant when you have a phone with internet access. Save the suitcase space. Bookmark a few good blog posts instead. (Ours, obviously.)

What to Buy When You Get There

Japan is ridiculously good at selling you exactly what you forgot to pack, often cheaper and better than what you’d have brought from home.

Uniqlo basics. Undershirts, socks, kids’ leggings, lightweight layers — all cheap, all high quality. Uniqlo stores are in every major city and many train station malls. If you realize mid-trip that you need another base layer or your kid spilled ramen on their last clean shirt, Uniqlo solves it for under 1,000 yen.

100-yen shops. Daiso, Seria, and Can Do are the big chains. They sell travel bottles, tenugui towels, rain ponchos, snack containers, small toys to keep kids busy, phone accessories, and about ten thousand other things you didn’t know you needed. We always make a Daiso run on our first day. Budget 2,000 yen and walk out with a bag of essentials.

Convenience store snacks. Onigiri rice balls for 120 yen. Melon bread. Egg sandwiches that somehow taste incredible. Japanese convenience store food is legitimately good, and your kids will find favorites fast. Don’t waste suitcase space packing snacks from home beyond a few emergency items.

Cheap umbrellas. If it rains — and at some point during your trip, it will — buy a clear vinyl umbrella from any convenience store for 500 to 700 yen. Everyone in Japan carries these. They work perfectly fine. Bringing umbrellas from home is dead weight when you can grab one for a few bucks the moment you need it.

The Actual Packing Mindset for Japan

Here’s the thing we wish someone had told us before our first trip: Japan is not a developing country where you need to “bring everything just in case.” It’s one of the most convenient, well-stocked, family-friendly countries on Earth. Convenience stores on every corner. Vending machines everywhere. Pharmacies stocked with everything you’d find at home plus better versions of most of it.

Pack light. Trust that Japan has what you need. Use takkyubin to forward your bags. Wear slip-on shoes. Carry cash. Load up the tablet. That’s the formula.

Your biggest enemy on a Japan family trip isn’t forgetting something — it’s carrying too much. Every extra kilogram you pack is a kilogram you’re hauling through Shinjuku Station at rush hour with a tired four-year-old on your hip. Pack less than you think you need. Then remove one more thing. You’ll thank yourself on day three.
