Infidelity investigation guides for Japan

These English guides help you prepare a non-urgent inquiry about a spouse or partner whose relevant activity is in Japan. They do not establish that infidelity occurred, that an investigation is necessary or that a request can be accepted.

Guide 1

Before confronting your partner

A change in communication, travel or routine can raise concern, but one behavior alone does not prove infidelity. Before a difficult conversation, separate what you know directly from what you think it may mean.

Make three short lists

  1. Facts you directly observed
  2. Questions you cannot yet answer
  3. Assumptions or interpretations

Use dates and time zones where they help. Do not access another person's phone, account, messages or private records to fill gaps.

Safety first: if a confrontation may put anyone at risk, do not rely on a business website for emergency help. Contact local emergency services or police.

Guide 2

Write a non-identifying first inquiry

A useful first message can be brief. Explain the general purpose, the connection to Japan, what you directly observed and what you want to clarify.

Illustrative wording:
“My partner has been travelling to Japan more frequently. I do not know the reason. I would like to ask whether this type of concern is within your scope.”

Do not include a third party's name, address, identity document, password, account details, private images or sensitive evidence in the initial form. Attachments are not accepted.

Guide 3

Questions to ask about an estimate

Do not make a decision from a headline price alone. Ask for a written estimate and check:

Submitting a website form does not authorize paid work or create a contract.

Guide 4

Privacy and safety boundaries

SPLASH will not accept requests involving stalking, harassment, discrimination, threats, retaliation, illegal access, unauthorized GPS installation, trespass, wiretapping or locating a person escaping abuse.

Before sending, consider whether someone else can access your email account, device notifications or shared screen. No communication method can be described as completely risk-free.

Messages may be machine-translated into Japanese and delivered to the operator through email and LINE services. A human must review a translated reply before it is sent.
