Information

  • This directory is non-exhaustive, there may be many active Japanese BBSes that are not listed here.
  • Most of the BBSes listed here are hosted on Japanese servers and follow Japanese laws regarding obscenity, slander, copyright, etc.
  • Each BSS has its own rules and conventions; one BBS's culture may vary wildly from another's.
  • Many BBSes — particularly those tagged #ero — contain explicit adult content and require users to be at least 18 years of age or older before entering.
  • Most of the BBSes listed here are at least somewhat active, but it's not uncommon for BBSes to depopulate or suddenly disappear without a trace.
  • Some BBSes are closely related to other BBSes, and may be run by the same individual or group. Relationships of this kind are shown here with a vertical line bridging the related BBSes together.
  • BBSes are generally listed here in order of posts per day, but if that information was unobtainable then other metrics were used.
  • Launch dates are derived from various sources and in some cases could only be estimated.
  • BBSes may be removed from this page if they are discovered to be dead or abandoned.
  • This site aims to be a living document, but the information listed here may be months or even years out of date by the time it is viewed. The information here should only be used as a rough guide, and not treated as a factual, up-to-date resource.
  • Virtually everything written on this site is based on original research. The HTML and CSS on this site was all hand coded from scratch, and the section icons are all original creations.
