Japanese Slot Machine Guide separates factual machine information from advertising and affiliate considerations. This page explains how information is researched, checked, and presented.

Machine coverage and retention

The machine database covers pachislot machines introduced for the Japanese market. Once a machine profile has been created, it may be retained as a reference after its normal installation period has ended or after current hall availability can no longer be confirmed.

Page retention is separate from current installation status and is not a legal-status classification. Installation periods, continued-installation treatment, and observed hall presence are checked separately from fixed specifications; the site does not infer an installation deadline from the rollout date alone.

Administrator research and official information

Numerical data, specifications, and explanatory information are researched and checked by the site administrator. Official manufacturer information, official announcements, and public-authority information are treated as the primary public references when available.

If an item is not directly stated in an official source, it may be presented as administrator research or independent research. Non-official information websites are not listed as public sources or references on this site.

Corrections and updates

Machine pages include a verification or data-check date where practical. Confirmed specification data is not treated as stale merely because a fixed amount of time has passed. Corrections are based on evidence and official information when available, not on commercial relationships.

Commercial independence

Advertising, sponsorship, or affiliate revenue does not determine which specification is published or how a machine’s lifecycle information is recorded.
