What time did Lazarus Episode 10 air in each region?
The Lazarus Episode 10 release date and time depended on the broadcaster and time zone. The Japanese broadcast took place on June 8, while the U.S. Adult Swim presentation occurred on June 6 or June 7 depending on the viewer’s location.
| Region or platform | Date | Time | Viewing context |
|---|---|---|---|
| Japan — TV Tokyo network and affiliates | June 8, 2025 | 11:45 p.m. JST | Episode-specific Japanese television premiere |
| United States — Adult Swim, Eastern Time | June 7, 2025 | 12:00 a.m. ET | U.S. television broadcast |

| United States — HBO Max | June 8, 2025 | Not specified | Streaming availability listed by the U.S. release guide; no precise hour was provided |
ORICON’s Episode 10 release report supports the June 8 Japanese episode schedule, while the U.S. release-time guide gives the Adult Swim date and time. The U.S. Eastern and Pacific dates look different because midnight Eastern occurs at 9 p.m. Pacific on the previous calendar day.

Why are the Lazarus Episode 10 dates different in Japan and the United States?
The dates differ because Japan’s scheduled broadcast was late on June 8, whereas the U.S. Adult Swim broadcast began at midnight Eastern on June 7. Pacific Time was still on June 6 when the U.S. broadcast aired. The Japanese June 8 premiere should therefore not be relabeled as the U.S. premiere date.
For a quick reference:
- Japan: Sunday, June 8, at 11:45 p.m. JST.
- U.S. Eastern: Saturday, June 7, at midnight ET.
- U.S. Pacific: Friday, June 6, at 9 p.m. PT.
Where could viewers watch Lazarus Episode 10?
U.S. viewers could watch Lazarus Episode 10 through its Adult Swim television presentation, with HBO Max listed as a subsequent U.S. streaming destination. The cited U.S. guide identifies June 8 for HBO Max but does not provide a release hour, so a precise HBO Max time should not be assumed.
