sarkujapan.com zoominfo.com/c/sarku-japan/33898946 SARKU Japan Japan's #1 independent service & wholesale network for foreign cars — founded 1993 in Chiba by Texan David J. Jones (in Japan since 1989) after seeing that owners of European/American cars in Japan were "orphans": parts take 6–8 weeks from Europe, service is scarce. SARKU built the full foreign-car infrastructure: 9 service centers (8 Kanto + Nagoya), a wholesale yard of ~4,000 imported cars (one of Japan's two largest), a parts warehouse of 30,000+ SKUs worth ¥700M+ (also one of Japan's two largest), plus procurement/export arms via US offices in Seattle (since 1997) and Florida — selling 20,000+ cars and serving 60,000+ active customers (~150 staff from 15 countries; ~120K monthly site visitors, 170K+ downloaded car-buying guides). Since 2018 it's owned by the Netherlands' Louwman Group (Europe's largest family-run dealer group, est. 1923). Motto: "Foreign cars. Japanese precision."

Not assessable
Evidence ladder
Attacker assertion only. Establishes: claim date, group, alleged victim.
Unlocks: incident narrative, operational impact. Still no compliance clock.
Unlocks: discovery date, data types, affected count, compliance clock.
Unlocks: materiality, stated response, full audit trail. Ceiling removed.
No regulatory filing corroborates this yet — it is the attacker's own assertion. Watch this entity to be notified the moment a filing corroborates or contradicts it.
