In “Rainbow Song,” Kishia Tomoya (Hayato Ichihara) learns that his good friend, Sato Aoi (Juri Ueno), died in an airplane crash somewhere over California. He leaves work to visit Sato’s family and provide support in any way he can.

Rewind a few years earlier, Kishia and Sato first meet under strange circumstances. Kishia has a bad tendency of stalking girls after they break up with him. He just so happens to be stalking Sato’s friend at work. When Sato hears about her friend’s stalker she becomes all creeped out by him. Meanwhile, Kishia attempts to befriend Sato in order to get closer to his ex-girlfriend. With persistence, Kishia is able to make friends with Sato and, in the process, has Sato falling head over heals for him. Unfortunately, Kishia is totally oblivious to Sato’s true feelings.

Back to the present time and Kishia is in Sato’s room, reading a letter she wrote years back. It finally starts sinking in what Kishia Sato’s true feelings were and, perhaps, his true feelings for Sato come to the surface.

Not since "Crying Out Love in the Center of the World" (Kou Shibaski and Masami Nagasawa), has there been two sisters as lovely as Juri Ueno and Yu Aoi. Speaking of "Crying Out Love", the setup of "Rainbow Song" has an eerily similar setup: start out in the present, go back in time to introduce main characters when they first meet, romance blooms, tragedy occurs, younger sister is introduced, jump back in time to the present, younger sister takes prominent role, while older sister is honored in memory. That in a nutshell describes both films to a tee. So what makes "Rainbow Song" something more than a generic retread of "Crying out Love..."? Well main reason would be J-U-R-I U-E-N-O. Once Juri Ueno appears in the film, the movie makes an amazing transformation from a run-of-the-mill jun'ai flick to something quite special. You do get the feeling of watching a rainbow appear after a summer shower. Definitely, Juri Ueno's best performance since "Swing Girls."

And that’s not to say the other performers in “Rainbow Song” were shabby in any way. Hayato Ichihara, as main character Kishia Tomoya, certainly exuded his own set of charms. Something as inane as the way he spoke (emphasizing certain syllables differently than others) made his character come to life. Yui Aoi, in her supporting role as the blind younger sister, was her usual charismatic self. While she sat on the bench and spoke with Kishia, her smile just glistened with this amazingly quiet exuberance that’s all Yu Aoi.
