Why You Need an Anti-Scam Phone
According to the National Police Agency, about 80% of phone scam victims were initially contacted through their landline. Criminals target landlines because elderly people at home are likely to answer, and caller ID spoofing is relatively easy. An anti-scam phone is the most direct countermeasure, physically blocking the entry point for these crimes.
Municipal subsidy programs are also helping. Starting with Tokyo and Osaka, about 200 municipalities nationwide subsidize the purchase of anti-scam phones, typically covering 5,000-10,000 yen. For households with elderly members, we strongly recommend taking advantage of these subsidies for early adoption. An anti-scam phone is a concrete step toward protecting your family.
Types of Anti-Scam Features and Their Effectiveness
Pre-Answer Automatic Warning Message
This feature plays an automated message to the caller before the phone rings - typically "This call is being recorded for scam prevention purposes." A National Police Agency pilot study found that phones with this feature enabled saw nuisance calls drop by about 75%. Since criminals avoid being recorded, most hang up upon hearing the warning.
The key advantage is that suspicious calls are filtered out before you even pick up. Once an elderly person answers, they risk being drawn in by a scammer's persuasive tactics - but if the phone never rings, no harm can occur.
Call Recording
This feature automatically records all calls, or only incoming calls. Recordings are stored on the phone's internal memory or an SD card. Recording serves two purposes: first, it deters criminals; second, it provides evidence if fraud does occur. As explained in our legal guide to call recording, recording a call you are a party to is legal in Japan.
Automatic Spam Call Blocking
This feature cross-references incoming numbers against a spam call database and automatically blocks matches. The database is updated regularly with newly reported numbers. Panasonic's "Nuisance Call Consultation" and Sharp's "Nuisance Call Filter" are representative implementations. Update frequency and database size are key comparison points, as they directly affect blocking accuracy.
Anonymous Call Rejection
Working in conjunction with Caller ID Display, this feature automatically rejects calls with withheld numbers. Since many phone scam calls are made anonymously, this setting alone provides meaningful protection. Note, however, that it also blocks legitimate callers who withhold their number (some hospitals, public phones, etc.).
Safe Answer Feature
When a call comes in, an automated voice prompts the caller to state their name and purpose. You can listen in real time and decide whether to pick up. Unlike voicemail, you hear the caller's voice live and can answer immediately if it is someone you know, or simply let the call drop if it seems suspicious. This makes it particularly user-friendly for elderly people.

Setup Steps and Usage Tips
Initial Setup
After purchasing an anti-scam phone, configure it in this order:
- Subscribe to Caller ID Display: Apply with NTT (440 yen/month). Caller number display is a prerequisite for anti-scam features
- Enable nuisance call prevention: Turn on "Nuisance Prevention" or "Spam Block" in the phone's settings menu
- Enable anonymous call rejection: Set "Anonymous Rejection" to ON. Optionally also block "Pay Phone" and "Out of Area" calls
- Configure call recording: Set "Auto Record" to ON and choose the storage destination (internal memory or SD card)
- Register contacts: Add family, your doctor, and frequent contacts to the phone directory. Configure registered numbers to skip the warning message so known callers are not inconvenienced
Informing Family and Friends
With anti-scam features enabled, callers will hear a warning message. Let family and friends know in advance that you have set this up for nuisance call protection. Configuring registered numbers to skip the warning maintains everyday convenience.
Regular Maintenance
Review the spam database updates, clean up recordings, and revisit your block list about once a month. Recordings in particular can fill up internal memory, so delete unnecessary ones regularly. SD card-compatible models alleviate storage concerns.
Municipal Subsidy Programs
Many municipalities subsidize anti-scam phone purchases. Most require you to apply before buying, so check your local program first.
- Eligibility: Households with residents aged 65 or older (varies by municipality)
- Subsidy amount: Typically 50-100% of the purchase price, capped at 5,000-10,000 yen
- How to apply: Obtain the application form from your municipal office or website and submit it before purchase
- Required documents: Application form, ID, and a catalog or quote for the phone you plan to buy
Availability varies by municipality. Search "[your city] anti-scam phone subsidy" or contact your local city/ward office. Combined with landline nuisance call protection settings, you can comprehensively fortify your landline's security.
Limitations of Anti-Scam Phones
Anti-scam phones are powerful but not infallible. Understand these limitations and combine them with other measures:
- Numbers not yet in the database: New spam numbers have a lag before they appear in the database
- Spoofed numbers: Calls spoofed to show a legitimate number cannot be detected by the database
- Warning message bypass: Some criminals do not hang up after the warning and attempt to engage by stating a plausible purpose
Beyond the phone's built-in features, share knowledge from how to block nuisance calls and the psychology of phone scams targeting the elderly with your family to build a multi-layered defense.
What to Check Before Buying
Before purchasing, confirm your current phone line type. Connection methods differ between NTT analog lines, Hikari Denwa, and cable TV phone services. For Hikari Denwa, you need to connect to the home gateway's (HGW) phone port. Check the manufacturer's compatible line list to ensure the phone works with your setup. Also plan the number of cordless handsets and charging cradle locations in advance for a smooth setup.
