Song title, music group?

About three or four years ago an all-male group (I think) had a JPop/JRap song where, in the the video, they sat around an outdoor pool during summer and watched girls in bikinis (of course) jump into the pool in slow motion. The video was shot in bright colors, and somewhat like a short film with credits rolling at the end. Anyone know the name of the song and group?

Is the video you mention like this?

"Shanghai Honey" by Orange Range

No, it's more of a Kick the Can Crew type of song. More of a pop or even a light hip hop sound than light rock. I do love Shanghai Honey. The video I'm thinking about is around the same time, though. Thanks for the guess.

this is similar not sure if its exactly what you want.

Thanks Shogun, but not that one either. The song I'm thinking about has no guitars. It's more pop hip hop than pop rock. Also, the guys do the singing/rapping while the girls in bikinis jump into the pool in slow-motion. The main reason I don't know the song and the group is because group name and song title is in kanji, and that I can't read. Thanks for the guess.

�gRAKUEN BABY�h??

Rakuen Baby is a bit closer to the song I'm thinking of in terms of genre, but the song I'm thinking of is slower. About as slow as Will Smith's "Summertime," and with the same light, summer-like feel to it. But with girls in bikinis jumping into a swimming pool in slow motion. Thanks for the guess, N.

Both group name and song title were in kanji?!!!!
That was not correct answer AT ALL...
My apologies, lonnie.

Ketsumeishi, Natsu no Omoide.

It took me more than five months to figure it out, but I finally found it. And the entire video, girls included, is shot backwards in slow- motion.
