July 2017    5th generation mobile communications systems' regulatory framework is proposed


On July 28, 2017, a advisory committee about new generation mobile communications systems, which is created in the Information and Communication Council, which is an advisory council to the Minister of Internal Affairs and Communications, presented its draft final report. The Ministry of Internal Affairs and Communications (MIC), is now asking for public comments to this draft final report.

Mobile communications systems have evolved and now so-called services of the 4th generation mobile communications systems have just started in the Japanese consumer market. The MIC started its regulatory development for the 5th generation mobile communications systems and this advisory committee has been working on requirements for the 5th generation mobile communications systems since October 2016.

The requirements include basic concept of the 5th generation mobile communications systems, how to acquire required spectrum, interference efforts, and technical specifications for three specific mobile communications systems: LTE-Advanced (FDD), LTE-Advanced (TDD) and WiMAX/XGP systems. How and when these systems start regulated are still unknown, but detailed regulatory developments for the 5th generation mobile communications systems will be done on these three specific systems and so relevant stakeholders should fully understand this report and subsequent discussions.

June 2017    IP network's interconnection charge is proposed 


On June 30, 2017, a study group about interconnection charge calculations, which is created under the Ministry of Internal Affairs and Communications (MIC), held its 6th meeting and presented its draft final report. The MIC is now asking for public comments to this draft final report.

IP technology has been introduced into telecommunications networks and, in the wireline network in Japan, IP network is becoming the mainstream. In November 2015, Nippon Telegraph and Telephone Corporation (NTT) announced that traditional switching system would face maintenance difficulties around 2025 and so the current traditional PSTN network should be migrated to IP network. Since then, the MIC, including this study group, has studied this migration issue. 

Based on this draft final report, the MIC will revise more than 10 relevant regulations under the Telecommunications Business Law around this autumn. Interconnection charge is core of wireline network business and understanding the direction of IP based wireline network in Japan should be mandatory for operators doing consumer telecommunications business in Japan.

May 2017    Current usage of relevant frequency band is disclosed


On May 12, the Ministry of Internal Affairs and Communications (MIC) presented current usage of relevant frequency band (714 MHz to 3.4 GHz) and its evaluation to this usage. The MIC is now asking for public comments to these results.

This study and evaluation started in 2002 and has been done every year. Around 2000, the MIC changed its frequency management from being kept inside to being shared openly, and this study and evaluation are part of this transparent radio policy initiative.

From 2013, when a similar study was done, the number of radio stations in this frequency band (714 MHz to 3.4 GHz) has been significantly increasing and, especially in the Tokyo metropolitan region, this number got doubled. In such a situation, the number of amateur radio stations decreased by 8.6% and this service is facing a difficulty of showing its competitive edge in the Internet era.

April 2017    Government is pushing forward IoT R&D


On April 11, the Ministry of Internal Affairs and Communications (MIC) started requesting project proposals contributing to Internet of Things (IoT) services and, on April 12, the MIC started requesting project proposals for using IoT test bed. The former are government contract projects and the latter are government subsidy projects.

These days, IoT is the most well-heard policy buzzword and the MIC and the Ministry of Economy, Trade and Industry (METI) are promoting this policy, part of which is the above government spending. Information and Communications in Japan 2017, which is a white paper about ICT policy and regulation, is presenting that ICT’s extensive use leads to from Ubiquitous to IoT. 

This buzzword, “Ubiquitous”, became well-heard, after the MIC used this word in its u-Japan policy in May 2004. In this regard, we believe that IoT is expected to lead MIC and METI’s ICT policy at least for the coming 10 years.

March 2017    New IoT wireless technologies' specifications were defined


On March 17, 2017, a study group under the Information and Communications Council, which is an advisory organization to the Minister of Internal Affairs and Communications, presented a draft final report defining technical specifications of Internet of Things (IoT) wireless technologies. The MIC is now asking for public comments to this draft final report.

The MIC is promoting IoT environments and making efforts to prepare suitable regulatory framework for them. Last October, the Minister requested the council to prepare a recommendation for IoT wireless technologies. This draft final report is a draft of this recommendation. 

This final report is proposing eMTC and NB-IoT technologies that are designed for IoT operations and the existing major mobile systems, LTE-Advanced (FDD) system and WiMAX system, are revised to add these technologies. After public comments are collected, technical regulations of these two systems will be revised to realize eMTC and NB-IoT implementation.

February 2017    Tokyo Olympic Game's spectrum plan was proposed


On February 10, 2017, the Ministry of Internal Affairs and Communications (MIC) proposed a spectrum plan for Tokyo Olympic Game, which will be held in 2020. The MIC is now asking for public comments to this spectrum plan.

During the Olympic Game period, many media staffs are expected to visit the Tokyo area and bring their special radio equipment. In the previous Olympics Games in London and Rio de Janeiro, additional 20,000 spectrum assignments were requested for media uses. 

After public comments are collected, the MIC together with the Tokyo Organizing Committee of the Olympic and Paralympic Games will finalize the basic spectrum plan for the Tokyo 2020 games. In every Olympic Games, surprising new media performances with cutting-edge technologies have been presented. The MIC can assign suitable spectrum for such media performances to be realized to surprise audiences more than competition itself?

January 2017    Classified corporation database under the overnment starts its operation


On January 19, 2017, the Ministry of Economy, Trade and Industry (METI) announced that corporation information that the government keeps is classified as database and its operation has started. This database is open to the public.

The government has been promoting sharing information, that it has, as databases with the public. Data.go.jp is a portal of these so-called government databases and this corporation database becomes a new addition. 

Corporate information included in this database this time is, in addition to basic information – corporation number, corporation name, address, capital and number of employees -, government grant, contract, license/permission, commendation. Currently, when somebody wants to know basic information of a corporation in Japan, he/she usually goes to Legal Affairs Bureau under the Ministry of Justice. Then, it cost around US$ 5 to acquire a paper with such corporation information. This corporation database might replace such a usage, because it is quicker and cost zero.
