Investigation Fee
Calculated based on investigator assignments, the time required, and the number of investigation days. Even when the subject’s movements are difficult to predict, we will share the anticipated time periods with you in advance.
How We Determine Fees
Investigation fees vary depending on the circumstances involved, the number of investigators, the time of day, and the travel area. We will hear about your situation at our office in Aobadai, Meguro, Tokyo, and plan the investigation without adding steps that do not serve your objective.
Before you sign a contract, we will clearly separate and explain investigation fees, actual expenses, and reporting-related costs. We will begin the investigation only after you have reviewed and accepted the details.

If an investigation requiring additional expenses becomes necessary, we will proceed only after obtaining your approval in advance.
