Ghibli ParkBuy Oct 10
Thirty minutes out at the old Expo park. Ghibli's Grand Warehouse, Howl's moving castle, Kiki's bakery, Satsuki and Mei's house — recreated with absurd care.
Tickets go on sale two months ahead on the 10th at 2 PM Japan time — for Dec 21 that's 10 PM on Friday Oct 9 in Los Angeles. First come, no lottery, six per purchase. Monday is a weekday, so weekday pricing applies: Standard ¥9,900 for the four of you, Premium ¥21,900.
Book the 10:00 Grand Warehouse slot — it is the only area with an assigned time, and you may enter up to an hour after it. A later slot is a trap: Mononoke Village and the Valley of Witches must be entered by 16:30 with your whole party, and a 13:00 or 14:00 Warehouse entry eats the afternoon before you get there. Standard is 3–4 hours of content, so a 10:00 start also puts both outdoor areas in daylight — sunset is about 16:45.
Standard covers the Grand Warehouse, Mononoke Village and the Valley of Witches — the two your boys would care about most are in there. Premium adds Dondoko Forest (Satsuki and Mei's house) and Hill of Youth, both smaller and more nostalgic. But some buildings inside the Standard areas carry extra fees, so check what's gated before assuming it's the bargain. And be clear what the whole thing is: not a ride park — walkthrough settings. Ask the boys before you spend either figure. The park closes Tuesdays; confirm the calendar for maintenance dates, which have fallen in early December before.
