What it is

tantei-labo.com (探偵ラボ) is an independent third-party database for comparing detective agency information based in Japan. It focuses primarily on the field of infidelity investigation, and also covers other detective service categories such as missing person searches, corporate investigations, and premarital investigations. The platform does not provide detective investigation services itself. Its core mission is to break down information asymmetry in the detective industry, and solve common pain points for users: difficulty finding a trustworthy detective, and high risk of falling victim to hidden fees.

Core Features & Pricing

The platform's core features include:

• Multi-condition filtering to search for detective agencies by region, service type, and specialty tags
• A free 4-question fee simulator that lets you estimate investigation costs for your case without entering any personal information
• Comprehensive detective agency rankings, with sorting options by overall rating, investigation capability, cost-effectiveness, and other metrics
• Moderated user reviews, where only authentic user experiences are kept, and bot posts and advertisements are removed
• Legal guides on choosing a detective, to help users avoid the risk of illegal investigation services

All features on the platform are completely free for all users, no fees are charged. At this stage, the platform also does not accept listing or advertising fees from detective agencies, which eliminates conflicts of interest at the source.

Pros & Cons Analysis

For advantages, the platform's biggest highlight is its independence: it explicitly states that it does not accept promotion fees from detective agencies, and rankings are based entirely on user reviews and data. This avoids the common "pay-to-rank" problem that plagues most comparison sites. Second, it has extremely high information transparency: all detective agencies are required to publicly disclose their fee calculation logic and note which groups their services are not suitable for, helping users avoid pitfalls ahead of time. It also has user-friendly design: all tools can be used without registration, and multi-condition filtering lets you quickly match your specific needs.

The disadvantages are very clear: it only caters to the Japanese market, so Chinese users almost never have a use case for it. The entire interface is in Japanese, which creates a barrier even for Chinese people living in Japan. It only provides information services, and does not get involved in subsequent transactions, so it cannot offer assistance if a service dispute arises.

Who It's For & Access From China

This website is only suitable for users who need to find detective services in Japan; regular Chinese users have no need to visit it. Currently, the website can be accessed directly from Chinese networks, no VPN is required.
