Especially, as stated above, GPS investigations by using GPS functions with the target's smartphone are o•en conducted for the tracking of the target. e Japanese Supreme Court has not ruled on such type of investigations. Also, the type of investigation is greatly di-erent from the investigation conducted in this case, so the decision that may come cannot be directly based on the ruling in this case. erefore, it is necessary to €nd essence of this rul- ing. On the other hand, there is a possibility that such unclear conclusion has some e-ect on the industry. When police con- duct GPS investigations, they lease GPS terminals from a pri- vate company, like with this case. erefore this investigation has some industrial relevance to GPS terminal manufacturers and leasing businesses. If police hesitate to conduct GPS inves- tigation because of the decision, there is no denying that such industries are a-ected. Moreover, in the near future, a new law for GPS investiga- tion is going to be established in Japan and GPS investigation will be a promising method of investigation that will be com- monly used. However, the legislative bill for GPS investigation hasn't been settled until now. e law will need to keep the balance between the e‡ciency of GPS investigations and the protection of human rights. ere still are various opinions about speci€c items of the law, and building a consensus on this may be quite a future task. Currently, the Japanese judicial system is facing a big prob- lem about GPS investigations. Additional Resources 1.
