The Reality of Stalker Phone Harassment
Stalker phone harassment takes many forms: repeated calls, silent calls, threatening messages, and relentless calls at all hours. According to the National Police Agency, over 20,000 stalking consultations are filed annually, with phone and message harassment being a primary form of victimization.
Stalker phone harassment severely impacts victims' mental health, with reported cases of insomnia, anxiety disorders, and PTSD. Personal safety products for women can provide peace of mind. Do not face this alone - early consultation with specialized agencies is key to preventing escalation.
Typical Harassment Patterns
Repeated Calls
Dozens to hundreds of calls per day. Even after blocking, stalkers may use different numbers or anonymous calling. Calls from various number ranges including 090, 080, and 070 are characteristic. Late-night and early-morning calls cause particular psychological distress.
Silent Calls
The caller remains silent throughout the call, aiming to instill fear. Silent calls are explicitly covered under the Anti-Stalking Act.
Threatening Messages
Threatening or intimidating messages sent via SMS or messaging apps. Content like "I know where you are" or "I'll harm your family" may constitute criminal threats.
How to Preserve Evidence
Evidence preservation is the most critical step. Whether consulting police or pursuing legal action, having objective evidence makes a decisive difference. See also how to document phone harassment evidence.
Save Call Logs
Record every call's date, time, number, and duration. Take screenshots of your call history and organize them chronologically.
Record Call Content
If you must answer, use a call recording app. In Japan, recording a call you are a party to is legal and admissible in court. Call recording apps ensure you capture evidence with every call.
Save Messages
Never delete SMS or messaging app content. Save screenshots showing both the message content and sender information.
How to Report to Police
- Visit your nearest police station: The Community Safety Division handles stalking cases. Scheduling an appointment by phone helps ensure smooth processing.
- Use the police consultation line (#9110): For non-emergency consultations. Anonymous consultations are accepted.
- Call 110 in emergencies: If you feel your safety is at risk, do not hesitate to call 110. Clearly state "I am receiving threatening calls from a stalker."
- Bring evidence: Present call log screenshots, recordings, and saved messages, organized chronologically.
- File a formal report: Consider filing an official victim report. Once accepted, an investigation begins.
Protection Under the Anti-Stalking Act
Regulated Behaviors
Japan's Anti-Stalking Act explicitly covers phone and message harassment as "pursuit behaviors":
- Making calls without speaking (silent calls)
- Repeatedly calling despite being refused
- Engaging in extremely rude or violent behavior
- Continuously sending emails or SNS messages
Warnings and Restraining Orders
Police can issue a "warning" to the perpetrator based on the victim's request. If the warning is ignored, the Public Safety Commission can issue a "restraining order." Violating a restraining order carries penalties of up to 2 years imprisonment or a fine of up to 2 million yen. Stalking behavior itself carries up to 1 year imprisonment or a fine of up to 1 million yen.
Changing Your Number and Additional Measures
If call blocking is insufficient, changing your phone number is a valid option. Contact your carrier to arrange the change. Share your new number only with trusted contacts and never post it on social media.

Strengthening Digital Security
Alongside addressing phone harassment, strengthen your overall digital security. Stalkers often track victims through multiple channels including social media, email, and location data.
- Review SNS privacy settings: Set all accounts to private, disable phone number search, and turn off location tagging on posts
- Change passwords: Change passwords for all accounts if the stalker may know them
- Stop location sharing: Review and disable all location-sharing features
- Scan for spyware: Run security scans to check for monitoring software; consider factory reset in severe cases
- Enable two-factor authentication: Use authenticator apps (not SMS) for all important accounts
Summary - Seek Professional Help Early
Stalker phone harassment tends to escalate if left unaddressed. Preserving evidence and consulting police or specialized agencies early is the best way to prevent further harm. The Anti-Stalking Act exists to protect victims - actively use legal tools like warnings and restraining orders.
