Japan may bring up additional cases of possible abductions of Japanese nationals by North Korea if it finds sufficient evidence to back its claims, Foreign Ministry Press Secretary Hatsuhisa Takashima said Tuesday.

"If there are any cases in which the Japanese side considers there is good reason or rationale to believe this would be a possible suspected case of abduction by North Korea, then we may raise that issue in the course of discussions with the North Korean side," Takashima said.

Additional cases would be brought up in October, when Japan and North Korea have agreed to resume negotiations to normalize diplomatic ties, as well as in the official-level talks to prepare for the resumption of negotiations.
