Leaders of Japan's ruling Liberal Democratic Party and its junior coalition partner Komeito have praised Prime Minister Abe Shinzo's achievements, while opposition party leaders said Abe failed to follow through on many issues.

Leaders of the LDP and its junior coalition partner, and opposition parties looked back on Prime Minister Abe Shinzo's tenure on an NHK TV program on Sunday, two days after Abe announced his intention to resign, citing worsening health.

Japanese Prime Minister Abe Shinzo's current tenure in office reached 2,799 days on Monday, making him the country's longest consecutive serving prime minister.

The previous record was 2,798 days set by the late Sato Eisaku.

Japan's Prime Minister Abe Shinzo has expressed his hope to hold a national referendum on constitutional amendment during his tenure as president of the governing Liberal Democratic Party. His time in that position will end in September of next year.

Abe spoke to former Osaka mayor Hashimoto Toru in an online program on Saturday. He said he still has one year and three months left in office as a leader of the party.
