Four attractions at Tokyo DisneySea had outages during the morning of September 10. At the named , only the DisneySea Transit Steamer Line in Lost River Delta was still marked DOWN, with its open interval at about 6 hours 6 minutes from a 9:14:58 a.m. JST start.
A fresh CrowdLevels row observed at about 3:40 p.m. JST still listed the Lost River Delta route as DOWN. This report keeps the other three attractions in the morning account without extending a current-status claim to them.
The morning cluster
At the earlier 10:08:50 a.m. JST history check, Anna and Elsa's Frozen Journey and Aquatopia had each been down about 1 hour 5 minutes, while Jumpin' Jellyfish had been down about 55 minutes. Those are bounded readings taken during the morning intervals, not final daily totals.
The steamer remained unavailable
The Lost River Delta route began its current interval at 9:14:58 a.m. JST. It was still marked DOWN at the named afternoon qualification, when the open interval had reached about 6 hours 6 minutes. Tokyo DisneySea's posted hours were 9:00 a.m. to 9:00 p.m. JST. The route is a park transportation attraction in Lost River Delta with a ride time of about six minutes.
Prior 90-day context
Before September 10, operating-hours-clipped summaries recorded 285 hours 37 minutes of Lost River Delta downtime across 81 days in the prior 90-day window. The steamer also had three recent interruptions of about 9 hours 30 minutes, on September 7, 8 and 9. That historical summary predates this incident and is context only.
No cause or reopening time was established in the checked records.
