When did toy story midway mania open in tokyo disneysea?

The provided sources describe the Toy Story franchise and its films but do not mention any attraction called "Toy Story Midway Mania" or its opening date at Tokyo DisneySea. Because no evidence is available in the verified material, I cannot determine when the attraction opened. If you need that detail, checking official Tokyo DisneySea press releases, the park’s website, or reputable news outlets that cover theme‑park openings would be a reliable next step.
