日本偏遠地區 (北海道/沖繩) 5G覆蓋範圍實測心得｜Lucky2 eSIM選擇分析

Testing 5G Coverage in Rural Japan (Hokkaido/Okinawa)｜Lucky2 eSIM Selection Analysis

When planning a trip to Japan, many people are particularly concerned about network performance in remote areas, especially when driving in Hokkaido or visiting the outlying islands of Okinawa. The actual situation shows that what travelers really need to focus on is not how fast an eSIM's 5G speed is, but whether the overall signal is stable, whether it's easy to connect, and whether the cost of use is reasonable.

Based on the current coverage and actual test data from Japanese telecom operators, eSIM networks primarily use LTE even in more remote areas of Hokkaido and Okinawa, but the overall connection quality is still sufficient to meet daily travel needs.

I. Current 5G and LTE Coverage in Japan

According to public information and network coverage from major Japanese telecom operators (Docomo, KDDI, SoftBank):

  • LTE coverage is close to 99%, basically covering the entire country, including mountainous areas and outlying islands.
  • 5G is mainly concentrated in urban core areas such as Tokyo, Osaka, and Nagoya.
  • Suburban areas of Hokkaido and outlying islands of Okinawa mostly still use 4G LTE, with 5G coverage still in the supplementary stage.

Conclusion: When traveling in Japan, LTE is the actual main network, not 5G.

II. Hokkaido Field Test: Stable but mainly LTE

Hokkaido is a vast region, including popular tourist spots such as Sapporo, Furano, and Shiretoko:

  • Sapporo urban area: 5G and LTE are used alternately, with stable speeds.
  • Suburban areas and natural attractions: Primarily LTE signal.
  • Mountainous areas and highways: LTE is the main connection method.

Actual user experience:

  • Google Maps navigation is stable.
  • WhatsApp, LINE messages are instant.
  • Uploading photos and short videos is normal.

III. Okinawa Field Test: Good in urban areas, mainly LTE on outlying islands

Network distribution in Okinawa is more significantly affected by topography:

  • Naha urban area: Good 5G coverage, faster speeds.
  • Northern region (Nago, Motobu): Primarily LTE.
  • Outlying islands (Ishigaki Island, Miyako Island): Depending on the telecom operator, most still have stable LTE connections.

Overall, Okinawa does not have serious signal loss issues, but 5G density is lower.

IV. Why Recommend Lucky2 eSIM

VI. Conclusion: Practical Options for Internet Access in Japan

Based on Japan's current network situation and test results:

  • Remote areas of Hokkaido and Okinawa primarily use LTE, which is stable and reliable.
  • 5G is mainly concentrated in large cities.
  • Network stability is more important than speed.

Therefore, for travelers, choosing a Lucky2 eSIM that can be used across multiple countries, has long-term validity, and offers stable LTE access is more practical and cost-effective than a single short-term Japanese internet card.
