Number overview
050-5810-7314 is an IP phone number (the 050 prefix). Multiple phone-number directories carry user reports describing solicitation calls in the name of the major tutoring service "Katei Kyoshi no Try" (as of 2026-08-03). A 2011 press release by the company group also lists this number as a contact.
Reported behavior
- Solicitation calls after requesting brochures or trial lessons
- Some reports describe repeated calls even after declining
Even for legitimate businesses, phone solicitation of people who have clearly declined is restricted under the Act on Specified Commercial Transactions. It is fine to refuse firmly.
How to handle this call
If you are not interested, state clearly that you do not want further solicitation. If the calls continue, block the number and consult the Consumer Hotline (188).
