Rakuten Mobile Coverage Map

Check Rakuten Mobile's network coverage in your area. Coverage quality varies by location, with major cities having the best service.

Coverage information updated August 2025. Rakuten Mobile operates ≈17,500 outdoor 5G base stations across all 47 prefectures with ≈99.9% nationwide 4G LTE population coverage. Network upgrades in 2024/25 via software and power output adjustments significantly expanded 5G coverage. For real-time coverage verification, visit the official Rakuten Mobile coverage map.

Coverage Legend

Understanding coverage quality levels

Excellent Coverage

Up to 1 Gbps (Sub-6 GHz with occasional mmWave)

Good Coverage

500-800 Mbps (good 5G in major cities)

Limited Coverage

300-500 Mbps (strong LTE with limited 5G)

Note: Speeds of 100-300 Mbps typically reflect strong LTE coverage with limited or no 5G deployment in rural areas.

Coverage Notes

Important information about Rakuten Mobile's network

Rakuten Network Areas: Major metropolitan areas including Tokyo, Osaka, Nagoya, Fukuoka, Sendai, Hiroshima, and Sapporo have excellent 4G/5G coverage with Rakuten's own infrastructure.

5G Network Expansion: 5G coverage in the Kanto region (Tokyo area) increased by ≈110% in 2024/25. Other regions saw expansion up to 100%, with Okinawa coverage doubling and Yamaguchi Prefecture expanding ≈40%.

Partner Network: Areas without Rakuten native coverage use au partner network. High-speed data allowance is 5GB per month, with speeds reduced to 1Mbps after exceeding the limit.

Indoor Coverage: Building penetration varies by construction type. Newer buildings and those near cell towers typically have better indoor reception.

5G Technology: 5G Sub-6 GHz provides wide-area coverage with speeds up to 1 Gbps. 5G mmWave (millimeter-wave) is limited to urban zones like major train stations and stadiums, offering even higher speeds but shorter range. 4G LTE coverage serves as fallback in all areas.

Network Infrastructure: Rakuten operates ≈17,500 outdoor 5G base stations across all 47 prefectures (as of Sept 2024), with more than 80% using Massive-MIMO antennas to support high speeds and improved capacity.

700 MHz "Platinum Band": Launched in June 2024, the 700 MHz band improves indoor/underground penetration and helps fill coverage holes. Rakuten plans to expand to 10,661 sites by 2033 as part of its long-term network development roadmap.

Coverage Updates: Network expansion is ongoing with new areas being added monthly. Remote and mountainous regions continue to see coverage improvements as part of Rakuten's 2033 expansion goals.
