Peru has withdrawn its ambassador to Japan, Luis Macchiavello and warned Tokyo against interfering in Lima's effort to extradite former Peruvian President Alberto Fujimori from Chile.
After Peru announced the decision to recall its ambassador, the foreign ministry issued a statement saying such interference by Japan would be unacceptable.
Japanese officials say they cannot comment because they have yet to be officially informed of the decision.
Earlier this week, Mr. Fujimori left Japan after five years in exile and flew to Chile with the intention of returning to Peru to run for president next year. He was arrested in Chile at Peru's request.
Mr. Fujimori fled to Japan in 2000 amid charges of corruption and human rights abuses stemming from his 10 years in office. Mr. Fujimori is recognized as a citizen in Japan, which refused to extradite him to Peru.
