Why WiFi is Still Japan’s
#1 Tourist Complaint
Hotels have it, but is it enough? Here is the reality of staying connected in Japan and how to prepare before you land.
Top 3 Connectivity Solutions at a Glance
1. eSIM
No physical card, instant setup, and cheapest for solo travelers.
2. Pocket WiFi
Shareable connection for families. Heavy to carry and requires charging.
3. Prepaid SIM
Reliable but easy to lose your original SIM. Buying at the airport is easy.

Why 31.5% of Tourists Are Frustrated
According to a 2023 survey by “Earth Walking,” WiFi environment is the #1 inconvenience for visitors. Despite “Free WiFi” stickers everywhere, the reality is different.
Complex Connection Procedures
“Free WiFi” often requires email registration, social login, or downloading a specific app. The forms are frequently in Japanese, long, and intrusive.
“I gave up after 10 minutes of trying to register my email.”
The Urban-Rural Gap
While 72% of visitors find WiFi convenient in Tokyo or Osaka, only 37% feel the same in rural areas. If you plan to visit hot springs or mountains, coverage drops significantly.
Hidden Passwords & Security
Passwords are often displayed only on TV screens in Japanese or hidden in guidebooks. Furthermore, many public networks are unencrypted, posing a security risk for credit card transactions.
Unusable Speeds
Hotel WiFi often throttles to a few hundred kbps during peak hours (8-10 PM), making video calls impossible.
Usability
Japanese UI design is often text-heavy and confusing for foreigners, leading to an “unfriendly” experience.
How Japan Compares to Neighbors
| Country | Avg Speed | Tourist WiFi Experience |
|---|---|---|
| Singapore | 386.96 Mbps | World Class. High quality public WiFi everywhere. |
| Taiwan | 291.38 Mbps | Excellent. “iTaiwan” is multi-lingual and easy. |
| Korea (Seoul) | 219.22 Mbps | Fast. High penetration in urban areas. |
| Japan (Tokyo) | 220.42 Mbps | Complex. Speed is fine, but access is difficult. |
