IMPORTANT NOTICE

Caution Regarding Spoofing Emails (Impersonation)

Dear Valued Partners and Clients,

We have confirmed that “spoofing emails” are being sent by individuals maliciously impersonating NOBU CORPORATION and our CEO, Nobuhiro Ikehata.

These emails have no affiliation with our company whatsoever.

■ Examples of Fraudulent Content

Invitations or requests to create internal group chats (e.g., LINE, WhatsApp).
Requests for employee lists or personal information.
Requests to send or scan QR codes.
Other unusual business instructions demanding urgent action.

■ Characteristics of the Emails

While the sender name may appear as “Nobuhiro Ikehata” or “NOBU CORPORATION,” the actual sender’s address is NOT from our official domain (@nobucorporation.jp). They often use free email services such as Gmail or Hotmail.

■ Our Request

If you receive such a suspicious email, please **do not reply**, do not open any attachments, and do not click on any URLs. Please **delete the email** immediately.

We are taking steps to strengthen our information security. Thank you for your understanding and cooperation.
