It has been a while since I was completing the quests for the last time. Mainly, after the third gameplay, I want new content to restart the game.
From this thread, it seems like Wakakko's role in this quest has changed. In fact, I remember that there was a bug relating to this... see, somehow things aligned so that Takemura gives me a phone call RIGHT about the time when Wakakko is supposed to call me / communicate with me, and it never happened after Takemura interrupted it.
I bypassed that by having game save before I entered the place with Judy, and then I managed to have the calls in the right order. Extremely fragile/immature quest infrastructure.
