Kawa no Nushi Tsuri: Hikyou o Motomete

River King (North America) or Harvest Fishing (PAL) (known in Japan as Kawa no Nushi Tsuri), originally released in English as Legend of the River King, is a fishing-themed role playing game series by Natsume (known mostly in America for its farming game series "Harvest Moon") that has releases on over 6 video game systems. Of these, 3 have been released in America, Kawa no Nushi Tsuri 3 and 4, dubbed "Legend of the River King" and "Legend of the River King 2" in the U.S. as well as Kawa no Nushi Tsuri: Wonderful Journey for the PS2 which was renamed River King: A Wonderful Journey. Natsume also plans to release versions for the PlayStation Portable and Nintendo DS.

In addition to the River King series which, as the name suggests, deals purely with freshwater fish, a spinoff series of saltwater fishing games has also been released called "Umi no Nushi Tsuri". The series has been released for the Game Boy, Super Nintendo, PlayStation, and Wii.

It is the first and only game on the PlayStation console because only the spin-off Umi no Nushi Tsuri SLPS 02172 was realesed in 1999 and was the last released in PSX.

You have 5 characters to chose at the beginning of the game and one to unlock.The characters are male and female.
