Coverage reality for remote work
In major cities in Japan, 4G is generally adequate for remote work (video calls, email, cloud). Outside cities, service can be intermittent.
Best-infrastructure cities for nomads:
- Tokyo: Excellent coverage; Metro LTE on most lines; dense buildings can blip indoors.
- Osaka: Strong 4G/5G; Dotonbori and Namba districts well-covered.
- Kyoto: Good coverage; bamboo forest in Arashiyama can temporarily drop.
- Hiroshima: Solid coverage; Peace Memorial area and Miyajima island both served.
Connectivity strategy
- Base: accommodation with Wi-Fi (speed-test before committing to a long stay).
- Backup: eSIM with a large or unlimited plan (15–30 GB/month minimum).
- Important calls: coworking space or verified-Wi-Fi café + eSIM hotspot as fallback.
Typical monthly consumption
Full-time remote work (~8 hrs/day): 60–100 GB/month if relying only on mobile data. With Wi-Fi as your base and data as backup: 10–20 GB/month.
