Infidelity Investigation
Is your partner showing suspicious behavior, like coming home late or dressing up suddenly? Infidelity can deeply affect relationships and family life, making timely evidence collection crucial. However, investigating on your own can be risky and difficult.
With over 17 years of experience, Lida Detective Agency handles infidelity cases from various countries. Our trained detectives gather evidence discreetly and legally, tracking your partner’s actions and interactions to confirm signs of infidelity. We also offer relationship counseling, reconciliation support, or assistance with divorce if needed.

Cross-border Missing Person Search
Looking to reconnect with a long-lost family member or an old friend? No matter who you’re searching for, Lida Detective Agency can help you find the person you've been looking for. Using clues like age, name, features, and memories, combined with our extensive network, we narrow down the search. We offer services across Japan and, even if the person is abroad, can conduct searches through local agents or detectives in other countries.

Stalking & Harassment Prevention
Stalking can cause severe disruption and emotional distress, and often, police may not provide effective solutions. Lida Detective Agency investigates the stalker's identity, collects evidence, and helps with legal measures to ensure your safety. We can also provide trained security personnel to stop the harassment and protect you.

Eavesdropping / Surveillance Prevention
Unusual static or pauses during calls may indicate eavesdropping. Lida Detective Agency’s cybersecurity experts can detect and eliminate surveillance on your devices or home. Contact us for an assessment and advice on whether further action is needed.

Surveillance
We assist in tracking the movements of a partner suspected of infidelity or family members whose whereabouts are often unknown. As long as the reason is valid and legal, we can monitor their activities through methods like tailing, observing fixed locations, and inquiries to track their daily routines and suspicious behavior.
