As one of the first countries to deploy 5G networks, Japan has been actively promoting the adoption of this technology, with a focus on transforming various aspects of its society, economy, and daily life. In this article, we will delve into the current state of 5G in Japan, exploring its development, deployment, and impact on the country.
History of 5G Development in Japan
Japan’s journey towards 5G began in the early 2010s, when the country’s Ministry of Internal Affairs and Communications (MIC) initiated research and development efforts focused on the next-generation wireless technology. The MIC collaborated with leading Japanese companies, such as NTT DoCoMo, KDDI, and SoftBank, to establish a 5G research and development consortium.
In 2014, the consortium successfully demonstrated a 5G prototype, achieving data transmission speeds of up to 10 Gbps. This breakthrough marked a significant milestone in Japan’s 5G development, paving the way for further research and testing.
5G Trials and Commercial Launch
Between 2015 and 2019, Japan conducted extensive 5G trials, with a focus on testing the technology’s performance, reliability, and compatibility with various devices and applications. These trials involved multiple stakeholders, including mobile operators, equipment manufacturers, and content providers.
On March 25, 2020, Japan’s three major mobile operators – NTT DoCoMo, KDDI, and SoftBank – launched their commercial 5G services, marking a major milestone in the country’s 5G journey. The initial rollout focused on major cities, including Tokyo, Osaka, and Nagoya, with plans for nationwide coverage in the following years.
Current State of 5G in Japan
As of 2023, Japan’s 5G network has expanded significantly, with all three major operators offering extensive coverage across the country. According to a report by the MIC, Japan’s 5G network covers over 90% of the population, with average download speeds exceeding 1 Gbps.
5G Network Infrastructure
Japan’s 5G network infrastructure is built on a combination of low-band, mid-band, and high-band spectrum frequencies. The low-band spectrum (700 MHz and 900 MHz) provides wide-area coverage, while the mid-band spectrum (3.7 GHz and 4.5 GHz) offers a balance between coverage and capacity. The high-band spectrum (24 GHz and 28 GHz) is used for high-capacity, low-latency applications, such as ultra-high-definition video streaming and online gaming.
5G Base Stations and Small Cells
To support its 5G network, Japan has deployed a large number of 5G base stations and small cells. According to a report by the MIC, there are over 100,000 5G base stations in Japan, with plans to increase this number to over 200,000 by 2025.
Small cells, which are low-power base stations that provide coverage over a small area, play a crucial role in Japan’s 5G network. These small cells are often deployed in urban areas, such as shopping districts and public transportation hubs, to provide high-capacity coverage.
