Number overview
052-386-0297 is a landline number in the Nagoya area (052). Multiple directories carry user reports describing sales calls in Chubu Electric Power's name pitching electricity-plan reviews (as of 2026-08-03). It is registered on jpnumber under the company name "GR Consulting", and Telnavi lists it as "GR / power-related sales" with contributions from 13 users.
This site previously stated that the number "poses as meter reading to press for home visits" and was "suspected of ties to illicit job schemes". Re-verification could not substantiate either statement, so we corrected the page to what the reports actually describe.
Reported behavior
- Uses Chubu Electric Power's name to pitch electricity-plan reviews or switchovers
- Reports of callers implying affiliation with the power company
Major power companies do not normally pressure customers into switching by phone. You can verify the caller against the contacts printed on your meter-reading slip or the official website.
How to handle this call
Even if the caller claims to be a power company, do not share your customer number or contract details. Refuse clearly if not interested, and block the number if the calls persist.
