'Uncle's Paradise' aka Mighty extreme Woman.(2006) – Shinji Imaoka.

The exhausted, hyper-sexualised middle-aged Takashi (Shiro Shimomoto) visits his nephew Harou (Mutsuo Yoshioka) in a quaint blue-collar fishing village. Due to an increasingly eccentric, demonstratively erotic medical malady, the grossly sleep-deprived Takashi prolongs his visit which saltily provides the lurid catalyst for a number of bizarre, often hilarious, surrealistic sexual escapades! Shinji Imaoka's exhilaratingly bonkers pink comedy features a deadly spider, a rudely penis perforating viper, a welcome generosity of nookie, a demonic love hotel, reincarnation, and a gigantic mythical squid! Sexy, episodic, and deliciously mad, Uncle's Paradise doesn't make a lick of sense, but the charmingly quirky performances, and fever dream narrative proved wholly irresistible! It comes as no surprise that the exquisite Minami Aoyama won the best actress prize at the Pink Grand prix ceremony.
