During the surveyed time period, the average 4G speed in Japan amounted to 25 megabits per second. In comparison, Singapore showed the fastest average download connection speed with 47 Mbps.
In Japan, 4G is now almost ubiquitous: Users across all operators experience time connected to 4G the majority of the time, with scores ranging from SoftBank's 97.8% to au's near perfect 99.0%. However, DoCoMo won the award for 4G Coverage Experience.
Rakuten has been a major global proponent of ORAN for both its 4G and 5G networks in Japan and as a supplier of technology outside Japan.
With an average download speed of 47.1 Mbps experienced by our NTT docomo users, the operator retains the Download Speed Experience award. In second place is au, with users experiencing 43.4 Mbps, ahead of SoftBank users on 37.9 Mbps and Rakuten with a score of 30 Mbps.
For medium users, who do a bit more, having 4GB to 8GB will suffice. For heavy users, who also stream videos and music several hours a week, 9GB to 12GB of data a month will probably do.
Fiber-optic cable networks
Japan's current fiber-optic commercial internet connections use optical fiber transmission windows known as L and C multi-core fiber (MCF) bands to transport data long distances at record speeds.
Other nations, including Japan, Hong Kong, and Sweden, also give their citizens access to the quick Internet. While several nations offer useful Internet, they have not yet introduced 7G or 8G networks.
In Japan the 5G experience continues to be far superior to older 4G technology. But it's not only the average experience which is better with 5G, but also the consistency of the mobile experience.
Australia has three main mobile phone providers - Vodafone, Telstra, and Optus - all of which operate using 2G, 3G, 4G, and 5G frequency bands on the GSM network.
Fastest Providers - Download
Speedtest Intelligence® reveals that among top mobile operators in Australia in Q4 2022, Telstra delivered the fastest median download speed at 96.16 Mbps.
Average speeds for NBN very high speed services
The average download speed for NBN very high speed services in March 2023 was 788.6 Mbps during all hours and 724.8 Mbps during the busy hours. The average upload speed was 46 Mbps during all hours and 45.8 Mbps during the busy hours.
Japan is reportedly planning a comprehensive strategy for "post-5G" (6G) technology by 2030 and it is believed that the new technology will be 10-times faster than the current 5G.
Luckily for you, the MVNOs easily accessible to tourists are mostly on the NTT DoCoMo network and some on the SoftBank network, so you will be fine 🤪. But… for the best overall performance, especially on 4G/LTE, NTT DoCoMo is the clear winner (best 4G/LTE coverage and the fastest 4G/LTE speeds).
While overall Download Speed Experience ranges from 24 Mbps to 52.4 Mbps, the 5G Download Speed scores are all over 100 Mbps, with impressive speeds of 139.6 Mbps (SoftBank), 151.1 Mbps (au), 161.4 Mbps (NTT DoCoMo) and 224.3 Mbps (Rakuten).
All three main mobile providers in Australia (Telstra, Optus, and Vodafone) now offer 5G phones and network access.
Countries like Norway, United States, China and Japan have launched 7G and 8G networks, in some places it is commercial and in some places it is still in testing.
Australian 5G networks are popping up, but not everyone has access just yet. This isn't unique to Australia; several countries have 5G, but coverage is still a fraction of that provided by 4G. If you're not familiar, 5G is the next upgrade to mobile networks following 4G.
China makes significant progress in 6G by achieving 100Gbps wireless transmission. The new development has potential.
The latest FCC Charter includes a 6G remit, alongside AI and machine learning, advanced spectrum sharing and other emerging technologies. “We're really the only part of the US government that's specifically focused on 6G so far,” says Brenner.
China to introduce early 6G mobile applications by 2025, putting the country on track to rolling out commercial services by 2030.
Countries in the world with the slowest internet
The five countries or territories in the world with the slowest network speeds are Afghanistan (1.71Mbps), the Yemen (1.79Mbps), Syria (2.30Mbps), East Timor (2.50Mbps) and Equatorial Guinea (2.70Mbps).
