A scandal has occurred at Nishi-Nippon City Bank. It has been revealed that an employee at the Shimonoseki branch uploaded videos and images containing personal information to social media. These posts spread online, and the bank issued an apology on the 30th.
According to the bank, the employee filmed inside the office using a smartphone and posted the footage and images on social media.
Some of the content included a whiteboard displaying personal information of seven customers as well as business targets.
The content was uploaded via the communication app BeReal and later spread to platforms such as X (formerly Twitter), causing public backlash.
On April 30, the bank released a statement on its website:
"As a financial institution that plays a significant social and public role and is built on trust, all of our executives and employees deeply regret this incident. We take this matter very seriously and will thoroughly enforce compliance and information management to prevent any recurrence."
The bank also stated that it will offer individual apologies and explanations to the affected customers.
Overview of the Incident:
In April 2026, a serious data leak occurred at Nishi-Nippon City Bank when an employee posted content on BeReal from inside a bank branch.
The post showed parts of the workplace environment
It was later reshared on social media (X / Twitter) and spread widely
Personal information of multiple customers (around 7 people) was visible
This became a major compliance and trust issue for a financial institution.
What Information Was Leaked?
According to reports, the images/video included:
Customers' names
Internal documents and computer screens
Business targets and sales-related information
Details related to financial products (e.g., investment services)
In short, internal bank information was exposed to the public
Why Did It Happen?
The design of BeReal played a role:
Users receive a random notification once a day
They are encouraged to post within 2 minutes
The app uses both front and back cameras simultaneously
This can lead to:
Posting without careful checking
Accidental capture of sensitive surroundings
Bank's Response
The bank took several actions:
Issued a public apology
Contacted affected customers individually
Promised stronger compliance and employee training
Key Issue: A New Type of Risk
This incident highlights a modern risk in the digital age:
1. SNS Design Risk
Apps that encourage instant sharing can increase mistakes
2. Human Error
Employees may treat posts as "private" but they can spread publicly
3. Organizational Responsibility
Insufficient rules or training on social media use
Why It Matters
For banks, trust is everything.
Even a small leak of personal data can:
Damage reputation
Lead to legal and regulatory consequences
Reduce customer confidence
Key Takeaway
This case shows that:
Even casual social media use can cause serious data breaches
Companies must adapt their policies to modern apps like BeReal
Employees need strong awareness of information security
