Where is the real life locations in the Pretty Cure All Stars DX3: Deliver the Future! The Rainbow-Colored 꽃 That Connects the World?

I want to know where is the real life location in all the Pretty Cure All stars DX series. "Pretty Cure All Stars DX: Everyone's Friends☆the Collection of Miracles!" and "Pretty Cure All Stars New Stage: 프렌즈 of the Future" are in Yokohama. "Pretty Cure All Stars DX2: Light of Hope☆Protect the 무지개, 레인 보우 Jewel!" is in Tokyo Bay. How about "Pretty Cure All Stars DX3: Deliver the Future! The Rainbow-Colored 꽃 That Connects the World" is set in what place in Japan?
