2-3 months is enough time to form a committee and establish the metrics that an acceptable plan would have to meet.

This is Japan we're talking about. I believe they require multiple late-night "socializing" meetings to figure out exactly what's going to happen. Then they just have a series of meetings to formalize what they decided on beforehand.
Then they gotta print and fax all the documents from those meetings for record keeping.
