“through the use of telecom facilities”
• According to the MIC,
• Telecom businesses that use telecom facilities located within the Japanese 
territory are under the supervision of the TBA.
• When telecom facilities are located outside Japan but controlled by an office 
located in Japan, such a business is also under the supervision of the TBA.

ii. …
Common, but inefficient solutions
• Obtaining voluntary cooperation from OTT‐telcos
• Not certain that the MIC can obtain cooperation from OTT‐telcos. 
• Revising the TBA or introducing a new law
• A written law/regulation can soon lose its effectiveness.
• OTT‐telcos can change much faster than a government drafts a 
law.
• Making new laws or revising old ones whenever exceptions appear 
will damage the predictability and the stability of the legal framework.

I do not want the new services
because they are annoying to me.
I will not use the new
services because they are
unnecessary to me.
The new services have to be
improved to be more user-friendly.
I want more new
services because they
seem attractive to me.
I do not have any
particular complaint.

As a communication services, LINE had to surpass the critical mass.
After getting authorization from users, LINE automatically imports 
contact lists from mobile handsets and sends notification messages to 
other users on that list.

Switching costs increase as the purchasing frequency increases.
Because of the technical difficulty of designing the 
questionnaire sheet, the survey was conducted 
with e‐commerce users, not with OTT‐telco users; 
therefore, we need to be cautious in translating the 
results.
More secure position in the market Less competition
Insufficient protection for end users
• Although look similar, there are clear differences between traditional 
and OTT‐telecom services.
• OTT services are not bounded by the secrecy of communications.
• In an emergency, telcos must prioritize “essential communications,” while OTT‐
telcos need not.
• OTT‐telcos do not have a legal duty to disclose terms and conditions to end users, 
and are not obliged to handle users’ complaint properly.
• This situation is not well shared with ordinary consumers.
• If the competition is not sufficient, OTT users may suffer greater 
disutility.
Proposals
I. Concern for competitive neutrality
II. Possibility of monopolistic leverage
III. Insufficient protection for end users
Challenge #1: Competitive neutrality
• To construct the definition of OTT‐telcos based on the service 
specifications their outputs should have in the end.
• Not based on the features the operator should have or how their services are 
produced
• This can maintain usability regardless of the changes in underlying 
technology.
• We have to focus on the retail market not on the wholesale market.
• This does not mean a return to the traditional sets of natural 
monopoly regulations.
• Considering the possibility of easy market entry, we can rely on 
market dynamism for optimal resource allocation.
Challenge #2: Monopolistic leverage
1. A separation between the OTT‐
application section and the underlying 
section and enforce open access 
regulation between them
2. An open access to personal information 
database
These can have a destructive impact on OTT’s  profitability, and thus may 
be better practiced only when the monopolistic behavior of a dominant 
OTT player starts to cause a serious concern.

Challenge #3: User protection
• There are many things a government can do.
• But, in a free market economy, it is better to use the market 
dynamism.
• incentivize OTT players to disclose the necessary information
• enable end users to choose whatever they want.
• Consumers need to have a corresponding level of literacy. 
• Enlightening campaign
• Subsidies for volunteer helpers
• An introduction “OTT sommeliers” who can translate technical parameters 
into plain language.
Borderless nature requires global cooperation
• Owing to the borderless and facility‐less nature of OTT players, any 
initiatives cannot produce any meaningful outcome if executed only 
by a single telecom authority.
• A window will open for regulatory arbitrage.
• If we want to reject the control of the Internet ecosystem by an inter‐
governmental organization, and keep it under the multistakeholder‐
ism, establishing an international voluntary or co‐regulatory 
cooperation must be an urgent concern.
