Japan’s legal squeeze and 3G shutdown are cutting the yakuza off at the number — can they still live?

Law as a social firewall

Japan’s post-2011 legal architecture has made everyday services — bank accounts, rental contracts, loans and even mobile phone subscriptions — a lever to exclude suspected organized-crime members from mainstream life. The nationwide "Boryokudan Exclusion Ordinances" (暴力団排除条例) and police-backed corporate declarations empower private firms to sever ties with people deemed linked to boryokudan. It has been reported that mobile carriers NTT docomo, SoftBank and KDDI embed “anti-social forces” clauses in contracts that require signatories to declare no gang affiliation, turning a simple phone application into a legal minefield.

Flip phones, old contracts — last legal footholds

That’s why some yakuza, notably Yamaguchi-gumi (山口組) members, still use ageing flip phones tied to decades-old contracts. Those 1990s “090” numbers and memorable endings — 8888, 7777, 1234 — are not nostalgia, but legal shelter: as long as an old contract remains valid and the network supports it, the user can claim continuity. It has been reported that attempts to circumvent the system — lying on a contract, using a proxy to sign, or otherwise fudging paperwork — have led to arrests and to evidence used in broader raids. Even small infractions, reportedly, can give police a lawful opening for much larger investigations.

3G sunset and a forced choice

The technical tide is turning against that shelter. It has been reported that KDDI and SoftBank began phasing out 3G in 2025, and NTT docomo has announced a complete end to 3G on March 31, 2026 — a practical death sentence for devices that carried those legacy contracts. Once base stations are switched off, the last legal lifeline disappears. What options remain? Formally quit the organization and go through police-recognized exit procedures — difficult and dangerous — or risk anonymous or fraudulent smartphone sign-ups and new, potentially prosecutable, offenses. Modernization of networks thus does more than upgrade speeds; it reconfigures who can participate in basic civil life. When even getting a phone number can be treated as a crime, the question hangs in the air: can a person still live inside that system?
