The eSIM Guide for Working Remotely in Osaka
When your income depends on a stable connection, sorting your data is the first thing to do — ideally before you even land in Japan. An eSIM is the easiest answer: no plastic SIM to swap, no airport queue, and you're online the moment you touch down at Kansai. Here's how to choose one, set it up, and size your plan for a remote-work stay.
eSIM plans and prices change fast (Japan pricing shifted noticeably in early 2026). Check your phone actually supports eSIM, and confirm current prices on the provider's site before buying.
eSIM vs pocket Wi-Fi vs physical SIM
- eSIM — best for most people: instant, no hardware, install before you fly. Needs an eSIM-compatible phone.
- Pocket Wi-Fi — worth it if you travel as a group or need to connect a laptop directly; it's one more device to charge and return.
- Physical SIM — fine, but you'll queue at the airport and swap out your home SIM. Rarely the best option now.
The main providers (2026)
Ubigi · Best all-rounder · DOCOMO network
Runs on NTT DOCOMO, which has the widest coverage — noticeably better on Kansai day trips to Kyoto, Nara, and rural spots. Simple 1GB / 3GB / 10GB / 50GB plans valid 30 days, plus recurring and annual options, which makes it the smart pick for longer stays.
Airalo · City speed · SoftBank network
Uses SoftBank and tends to be fast in the big cities. Straightforward one-off plans (7/15/30 days, 1–20GB). Note: Japan prices rose sharply in early 2026, so it's no longer the automatic bargain — compare before buying.
Holafly · Unlimited data
The pick if you hotspot a lot or stream heavily. 'Unlimited' with a fair-use policy of roughly 2–3GB/day of full-speed data. Pricier — think around $27 for 7 days and about $75 for 30 days.
Which one for a 2-week Workation?
- Mostly working from stays and coworking (Wi-Fi everywhere): a 10GB Ubigi or a mid-size Airalo plan is plenty.
- Heavy hotspotting or streaming on the go: go unlimited with Holafly.
- Lots of Kansai travel or rural side-trips: choose a DOCOMO-based plan (Ubigi) for coverage.
- Staying a month or more: Ubigi's 50GB or recurring plan usually wins on value.
How to set it up (before you fly)
- Check compatibility: most iPhones (XS and newer) and recent Android flagships support eSIM.
- Buy and install the eSIM at home, on Wi-Fi — you'll scan a QR code or add it in-app.
- Keep your home SIM active for calls and 2FA codes; set the Japan eSIM as your data line.
- Turn on data roaming for the eSIM line once you land (this is normal for eSIMs).
- Screenshot the install QR/details in case you need to reinstall.
On the November Workation you'll have fast Wi-Fi at your stay and the coworking space, so a mid-size data plan is usually all you need — we send every participant a simple setup checklist before arrival.
