Quick Summary (Key Takeaways):
- Oasis 21 Restriction: Oasis 21 in Sakae—formerly Nagoya’s top Halloween street hub—is strictly restricted or fully closed on October 31 night (typically after 5:00 PM). Costumes and street gatherings are discouraged inside the complex to prevent severe overcrowding.
- Surrounding Areas: Large crowds naturally spill into Hisaya-odori Park and adjacent Sakae streets, but security presence is extremely high.
- Best Alternatives: For a safe and hassle-free celebration, attend ticketed club parties in Sakae/Shorai or visit theme parks like Legoland Japan.
- Local Rules: No street drinking, take all trash home, and never board public transit with realistic weapon props or excessively bloody costumes.
The Big Shift: What Happened to Halloween at Oasis 21?
Until around 2019, Oasis 21 was widely celebrated as Nagoya’s “holy land for Halloween cosplay”. The management even provided changing rooms and makeup facilities for costumed visitors.
However, following concerns over crowd control, trash, and safety incidents in major urban hubs across Japan, Nagoya City and Oasis 21 management implemented strict access restrictions starting in recent years.
- Oasis 21 Closures: On October 31, the underground plaza (“Spaceship Oasis / Gingano-Hiroba”) and the upper roof garden (“Water Spaceship”) typically close early (around 5:00 PM), with barricades erected and security guards posted.
- Hisaya-odori Park: Access to certain eastern walkways and lawn areas near the Chubu Electric Power MIRAI Tower is regulated or restricted after dark.
- MIRAI Tower Illumination: The TV tower often turns off its lights on October 31 night to prevent massive crowds from gathering for photo ops.

Essential Halloween Etiquette & Rules for Tourists
To ensure a safe night and maintain good relations with local residents, foreign tourists must follow these strict guidelines:

| 4. No Street Drinking | While Japan allows outdoor drinking in general, local police strictly monitor public intoxication and loud noise in Sakae during Halloween night. |
| 5. Respect Private Property | Do not enter convenience store restrooms or hotel lobbies solely to change costumes or apply makeup. |
