Learning jiu-jitsu in Steglitz-Zehlendorf

A long-established Steglitz school — `Kampfsport seit 1906` — whose Brazilian jiu-jitsu is unmistakably its own programme rather than a renamed traditional class: BJJ, Jiu-Jitsu and Kyusho Jitsu run as three separate menu entries, and the BJJ page describes Gi and No-Gi, throws as well as ground work (`denn BJJ Kämpfe beginnen im Stand`) and hard sparring at the end of every session. It publishes an affiliation — `Die Sportschule Rahn gehört zum internationalen BJJ Team Cicero Costa PSLPB` — and prices covering the whole school rather than one course: `1x Woche — Erwachsene 57,50 € /Monat` up to `Unbegrenzt — Erwachsene 77,50 €`, each tier reading `Alle Sportarten / Flexible Zeiten / Probetraining inklusive`, with no joining fee in sight. The BJJ class is `ab 14 Jahren`. The thing to get right before going is the door: the school publishes `Die Sportschule ist momentan sehr voll` and `Bitte erscheint nicht unangemeldet`, and plainly `Leider ist die Nachfrage so groß, dass wir unangemeldete Interessenten wieder nach Hause schicken müssen.` Sign-up for the two free trial sessions runs only through its `MySports` app. There are two addresses — `Nicolaistraße 13-15` in Lankwitz and `Goerzallee 188` in Lichterfelde — and which holds the BJJ sits in the app's course titles, so check when you book. Worth asking on the mat: the BJJ page names two different men as its black-belt coach in three sentences, and neither belt carries a grantor

Why we say it: Every quoted byte is the school's own sportschule-rahn.de, read 2026-08-17 under robots `User-agent: * / Allow: /` with no crawl-delay (berlin-d2-ledger-w1.md §C.23). The capacity lines are quoted verbatim with their read date under §18.3, with the `closed`-side polarity and booking-required flag §19.4 added — they are §18.3's second surface, access prose with no capacity vocabulary in it, which a term list scores as no signal and which nonetheless decides whether a beginner gets on the mat. Two venues publish as two pins under §13.7; which one holds the BJJ is stated as unpublished because the school directs that question into an app behind a login that was not entered, and no schedule is claimed for the same reason and under §19.5. The three-way instructor conflict is quoted in full and left unresolved; both black belts ship without lineage under §10.10. The `gemeinnützig`/`GmbH` conflict and the two spellings of the network are carried, not normalised
