Hidden Behind the Fridge: Police in Japan Say a Couple Ran a Phishing Operation From a Hotel Room

.

What Police Say Happened

Hyogo prefectural police announced on October 15 that they had arrested Ye Jiafeng, 39, and his wife Shen Qi, 39. Both live in Kobe's Chuo Ward. Ye is suspected of obstructing a hotel's business through deception and of related offenses.

According to Japanese media reports, Ye checked into a Kobe hotel in May 2025 under a false name and address. He is accused of hiding a small computer behind the refrigerator in the room. Police say the machine was then controlled remotely by another person.

Police have not disclosed how the couple responded to the allegations. Both are suspects, and no verdict has been reached.

How the Scheme Allegedly Worked

The emails pretended to come from credit card companies. They contained links to fake websites designed to trick recipients into typing in their card numbers and personal details. This technique is known as phishing (fraudulent messages that imitate trusted companies to steal data).

Investigators found records of at least 480,000 sent emails on the seized computer. The device also held about 2.4 million email addresses, apparently the list of intended targets.

Why the Hotel Wi-Fi Mattered

The suspects reportedly did not hack the hotel. They simply plugged their own device into the hotel's guest network, which gave the fraud a built-in disguise.

Every internet connection has an IP address (a numerical "return address" that can be traced). Any trace of these emails would first lead to the hotel, not to the people running the scam. Japanese reports say police believe this was the point: to keep the true location of the operator hidden.

The scheme came to light when a suspicious recipient looked at the technical details of the email. That person used the IP address to contact the hotel, according to Yomiuri TV.

A Second Case and a Wider Investigation

While investigating, police uncovered a separate credit card fraud case. Ye and Shen are accused of using another person's card details to buy three items, including down jackets, worth about 470,000 yen at a Kobe shopping facility on January 1 this year. They also face suspicion of computer fraud.

Jiji Press reports that Ye had already been indicted over similar phishing emails sent from a computer hidden in a different Kobe hotel. That case dates to July and August. Police suspect a Chinese criminal organization that repeats this method is behind the operations.

Hong Kong's The Standard reported that police seized as many as 74 smartphones from the couple's home. Investigators are examining those devices, the origin of the card data and the flow of money. They also want to know whether the couple acted on instructions from others.

A Pattern Across Asia: Hotels as Hideouts

Fraud operations that use hotels as cover are not new. In August 2026, Hong Kong police arrested two men who allegedly sent scam messages from a hotel room. Officers found 110 SIM cards and a modem pool (a device that runs many SIM cards at once) there. Victims lost more than HK$500,000.

In Vietnam, police arrested two hotel operators in July 2026 for housing four Chinese nationals who had entered the country illegally. Those four are linked to an ongoing online fraud investigation.

Japan's hotel industry faces a different problem at the same time. Microsoft reported a phishing campaign aimed at Japanese hotel staff, active since April 2026. It uses fake guest complaints to lure employees into opening malicious files.

What Travelers and Hotels Can Do

Scammers frequently pose as hotels, booking platforms or card companies. They often claim there is a problem with a reservation or a payment.

A few simple habits help:

• Do not click links or open attachments in unexpected emails.
• Do not enter card details on a page you reached through an email link.
• Contact the company through its official website or the phone number on your card.

For hotels, the case shows that a guest room network can become a tool for criminals. Staff may want to check rooms and network activity more carefully.

Outlook

The investigation is ongoing. Police are working through the seized devices to find other victims and to establish who controlled the computer remotely. Whether a larger cross-border network is behind the case remains open. Court proceedings will have to show which allegations hold up.
