Essential tips for travelling in Japan
Everything you need to know before your 2025 trip
It was somewhere between the cinnamon-scented lanterns of Osaka’s December markets and the snow-dusted torii gates of Kyoto that I realised how much a well-prepared phone matters. Japan in the festive season is a sensory feast—twinkling illuminations, midnight shrines, and bustling streets where you can lose your bearings in a heartbeat. Even with years of travel under my belt, I found myself searching for the best way to stay online in Japan—especially during those cold winter evenings when getting lost is a little less romantic and a lot more inconvenient.
Last time I visited Japan over New Year’s, the crowds at Shibuya Crossing were thick enough to swallow up even the most seasoned explorer. What saved me? Not a paper map, but a digital SIM that didn’t blink when local networks slowed under the weight of fireworks livestreams and holiday Instagram posts. Trust me, the right connectivity makes all the difference.
Quick Facts
- Winter in Japan means crowded hotspots and patchy public Wi-Fi, so plan for reliable mobile data.
- eSIMs offer instant activation—no waiting at kiosks or deciphering vending machines.
- Graba SIM’s Data Pulse lets you monitor usage on the fly; no more nasty surprises.
- Japan’s festive markets and illuminations can drain your battery and data—be ready.
- 24/7 chat support from Graba SIM comes in handy when you’re troubleshooting at midnight in Sapporo.
What you should know about Japan’s winter connectivity
Japan’s mobile infrastructure is top-notch, but it’s not always smooth sailing—especially in winter. Tokyo’s major train stations (Shinjuku, Tokyo, Ueno) become sardine cans after sunset, and network congestion is a real headache during holidays. I’ve seen even locals grumble when data slows to a crawl as everyone uploads New Year’s shrine selfies at midnight. Public Wi-Fi exists, but it’s patchy and often requires awkward registration steps—in Japanese. The free Wi-Fi at Christmas markets in Yokohama and Sapporo? More promise than reality, especially when thousands flock for mulled wine and Christmas illuminations. You’ll want your own data connection for navigation, translations, and those spontaneous street food finds.
Why This Matters
Japan’s festive season brings more crowds, more devices, and more demand for reliable data—especially if you’re exploring at odd hours or moving between cities.
How eSIMs make Japanese travel simpler
The old routine involved queuing at airport kiosks for plastic SIMs, or—if you’re like me—fumbling with finicky vending machines after a red-eye. With eSIMs, and especially Graba SIM’s instant activation, you can land and connect within 30 seconds. No need to swap out cards or worry about losing your home SIM.
I tested Graba SIM’s Japan eSIM on my iPhone 14 last Christmas. Data Pulse showed my usage right on the lock screen—hugely helpful when streaming the Sapporo snow festival’s light show. You get real-time updates, so you can budget your data (and your yen). And if you get stuck—say, late at night when you’re transferring at Shin-Osaka—the live chat support is surprisingly responsive, even at odd hours.Instant connectivity for Japan

Final Thoughts
Winter in Japan is a whirl of light displays, spirited crowds and culinary surprises around every corner. Staying connected isn’t just about convenience—it’s about confidence to follow your nose (or tastebuds) off the beaten path. From experience, having a digital SIM sorted before the journey means one less thing to worry about, letting you focus on what matters: sampling snowy Christmas cakes, ringing in the New Year at midnight, and—if you’re lucky—catching Mount Fuji’s first sunrise of 2025.
