What Happens When You Answer This Call?
You answer. An auto voice starts. It says something like: “Help us with a quick survey on your power bill.”
Then it asks: “Is your monthly power bill over 10,000 yen? Press 1 for yes, 2 for no.”
If you press, it sends you to a real person. They ask for your address. Your name. Your power contract details.
They might say they are from a big power firm. Like Chuden or Kyuden. But they are not. It’s a trick to get your info.
Some calls ask about solar panels. Or your family size. Or if you own your home.
One user said: “They named my firm’s money boss. Then talked about savings.” But most are about power.
User Stories and Reviews
Many share their tales online. Here’s what they say.
- “It was a robot voice. Asked about my power use. I hung up fast.”
- “They said they were from Mid-Japan Power. Wanted my home details. Felt wrong.”
- “Called at night. Asked if I have solar. Then pushed to switch plans.”
- “Pretended to be police once. But mostly power stuff.”
Thousands of comments exist. Most call it junk or scam. Some say it’s sales from money firms like Daiwa. But power themes win out.
In one area like Nara, calls hit many on the same day. Odd, right?
Why It’s Likely a Scam
This fits scam signs. Fake names. Auto surveys to hook you. Ask for private info.
Real power firms don’t call like this. They send mail or use known numbers.
Goal? Get your data. Sell you bad plans. Or worse, steal identity.
No real firm ties to this number. That’s a red flag.
If it was safe, fewer bad reports.
