How SphereScout prepares this business contact CSV

SphereScout turns public business profiles into a category-and-location export. The process uses the business categories shown in the current page breakdown and keeps official registers, classifications, licences, and inspections separate from the file.

Match the displayed business categories
SphereScout selects public business profiles matching the categories shown in the current page breakdown. These labels define the file's scope but do not replace official activity codes or authorizations.
Structure available public details
SphereScout organizes the available business name, category, location, website, email, phone, and public profile fields, then normalizes and deduplicates contact values for export.
Publish coverage and deliver the CSV
SphereScout refreshes public business profiles regularly, publishes the latest collection date and available coverage totals, and delivers the selected records as a structured CSV.

Using business contacts in Japan

A published or purchased address is not blanket permission for advertising email. Japan's Act on Regulation of Transmission of Specified Electronic Mail is consent-led and identifies prior request or consent, an existing business relationship, and limited statutory exceptions. Commercial messages must carry the required sender information and must stop after a refusal. Personal information remains subject to the APPI.

Read Japan's official commercial-email law and APPI materials

Keep recipient-level evidence of the request, consent, business relationship, or specific exception relied on before sending advertising email.
Do not infer consent from a public listing, custom domain, role inbox, or purchased spreadsheet.
Display the required advertising designation, sender name and address, and a valid email address for refusal as applicable.
Stop sending after the recipient asks not to receive the advertising email and maintain a suppression list.
When a contact identifies a person, define and disclose the utilization purpose, limit use to that purpose, and apply appropriate APPI safeguards.
Validate that the business, operating company, geography, and offer are relevant before choosing email, telephone, or another channel.
The commercial-email rules do not grant permission for indiscriminate calls. Identify the caller and purpose, contact at reasonable times, keep the offer relevant, apply the APPI when a number identifies a person, and suppress further calls after an objection.

Classify the contact route before outreach

Evidence

Treatment

Consent or relationship evidenced

EvidenceA retained request or consent record, an existing business relationship, or another documented statutory basis for the intended advertising message.

TreatmentSend within the evidenced scope, include the required sender information and refusal route, and preserve the evidence.

Public business route only

EvidenceThe address or number appears on a business profile, but there is no evidence that the recipient requested or consented to advertising email.

TreatmentUse the profile for qualification. Do not treat publication alone as email consent; obtain permission or use a lawful alternative channel.

Identity or source unresolved

EvidenceThe domain, business, operating company, recipient, source context, or current status cannot be confirmed.

TreatmentValidate or exclude the record before contact. A Corporate Number match does not establish control of a branch inbox or permission to message it.
