From this evidence bundle, the September 7 entry at Shimokitazawa Altoto only yields what looks like basic daytime hours. A specific event title, lineup, price, and musical direction cannot be grounded here, so it does not resolve cleanly as a standalone DJ event. For now, it is best treated as a partial venue schedule note rather than a fully identified party. No stronger claim is supported by the evidence.

ConceptThe available evidence is too thin, so this is best held as an unconfirmed venue listing.
