Universal Studios Japan’s 2025 Halloween season (4 Sep–3 Nov) adds a Pokémon-forward daytime party alongside the usual scare nights.

Day: Pokémon UNSTOPPABLE Halloween Party

Gramercy Park turns into an outdoor concert vibe with DJ Pikachu vs DJ Gengar energy—music, dancing, and character moments aimed at fans rather than pure horror.

Night: Horror Nights

After dark, scare mazes and haunted streets return for guests who want the fright track. Plan stamina if you do both modes in one day.

Trip tips

Buy dated tickets early, check official showtimes, and keep a Japan eSIM for park maps, wait times, and return trains to Osaka.
