Limit of Love: Umizaru

Limit of Love: Umizaru (Limit of Love 海猿 , Rimitto obu Rabu Umizaru ) , also known as Umizaru 2: Test of Trust[1] is a 2006 Japanese action drama film directed by Eiichiro Hasumi. It is the second feature-length film and third of the Umizaru projects, set after the film Umizaru and the 11-episode drama series Umizaru Evolution. The film stars Hideaki Itō as Japan Coast Guard (JCG) rescue diver Daisuke Senzaki, and Ai Kato as his love interest Kanna Izawa. It is the second of the 3 part film and television project, which is adapted from the popular manga series Umizaru by Shūhō Satō.

Umizaru (海猿) means "Sea Monkey"; a derogatory label slapped on the rescue diver trainees by local townsfolk of the city of Kure due to their excessive and uninhibited behaviour during off hours.

The film recorded the 2nd highest-ever box office grossing in Japan, trailing only Bayside Shakedown 2. The opening weekend of the film was a phenomenal 442% improvement on the opening weekend takings of the first film Umizaru.

Hideaki Itō, the male lead, has a Divemaster license awarded by PADI Japan; a professional diving qualification. The theme song is Precious, from vocalist Yuna Ito.
