In Japan, the time it takes for a criminal case to go from resolution to prosecution isn't fixed. Generally speaking, if there are no special circumstances such as delays, the prosecutor usually decides whether to prosecute within 23 days after the suspect is arrested.
If the police believe it is necessary to arrest the suspect, they can apply for an arrest warrant from the judge. Once the warrant is issued, the police must hand over the case to the prosecutor within 48 hours.
Japan adopts a strict single-charge indictment system to prevent pre-judgment, meaning the case generally won't be pre-tried. Once the prosecutor completes the paperwork, the case can proceed to court.
Minamoto Tamako, holding on to a slim hope, asked if the case could be withdrawn for a retrial, and Kinosaki Shoujin gave a definitive answer:
No.
