It feels like within two chapters it already advanced what it would take most mangas five volumes, for example Pastel. I'm wondering if the author can keep up this pace or will it fall into the trap of sexual gags. Either way a pretty good read for now.

Finally a manga that does all of the following.
1. The main Protagonist is NOT a loser.
2. Its a harem where there is only ONE couple. The rest are just there.
3. The couple gets together in the BEGINNING of the manga
4. SEX. A perfect amount. Not too much, and not too little.
5. People actually trying to get the main couple together.
6. No dark deep secret of the past.

Oh, and the description is kind of misleading. The "ex-girlfriend" doesnt really play a part in this story that much. Its mostly about the 3 Onsen girls, and the main guy.

Went through the five volumes of raws and I'm impressed. This series makes My Balls look tame at times. Hell, sex is pretty much the main topic in every chapter. It isn't just the stereotypical nosebleed crap either. This is the "thank god they got together," "that's so romantic," and even "wow I can't believe they did that" category. Just flipping through this with my garbage Japanese translation skills was a hoot. Looking forward to more of this series.

A light-hearted read for those softcore hentai lovers out there, Koibana Onsen employs no subtleties that would cause the reader to think twice on the romance that unfolds. Flat characters revolving around an emerging, linear passion provides an easy and light atmosphere that causes the reader to crave for more. The sex is not wanton, and principles are not abandoned.

This got a really nice slice of life - style story, very nice art, and smooth atmosphere.
I read this manga whenever I need some relaxing after a hard day at work and believe me, it helps ^^.
Well, I learned some stuff from this manga, honestly.
I dont know if its true and really thought through, but the way the author describes sex and the way to handle it, really makes you think about it a little longer after reading this. (yeah, hard to deny it... it's really 75% about sex here ... although its put into a nice ethic jacket.)
great manga all in all!

Pure Awesomeness.
I read it, pretty intense too, i love how the guy isnt such a wimp and the other crap.... i agree with flapple on his comment and how it has all of the following stuff

I give this a much deserved 10. Why? Well if you read it, you will find out that a series that is labeled a genre it should stick to it right? well, lets see. Comedy: Check; Harem: Check; Adult: Check; Mature: Check
As for Seinen, Ecchi and Romance, is it's focus, it's very adult in it's approach at love, but it doesn't take anything too serious. It's very Ecchi in a cute harmless way, but the Sexual tension and love from the couples is pure and real, just like Kenjiro's earlier work No Bra, he takes a love seriously, and the Romance could not be better, in it's risque and very realistic sense of overwhelming feelings you get in that certain mood, you feel it radiate from this manga. Also one thing i like that they do, is give you a sense of embarrassment to be caught in the act, along with great art, it makes a great sense of personality from the manga.
Overall: Genius!!! Great Art!!! Real Sense of Romance!!! Hilarious!!!
And Great Ecchi Scenes!!!

great manga! i love No Bra, other manga from this author, and i started reading this one. At first, i just was reading it cuz fuuka is very alike yuki, from No bra(only in the appearance, heh), but it is a very good read. This manga isn't alike alot other, with the protagonist being a perverted loser. the guy is very kind, and the girls are very good too(heh).

An amazing read for those of age. There isn't anything lacking that I can think of, and the author does an amazing job of storytelling here (slice of life style). Love the art, characters, humor when it is there, mature scenes, and w/e you can name... but there is no such thing as perfection; and this manga is no exception; so a 9.5 will do.

No actual private parts are drawn but it's very much hentai. With that said, it has a story; albeit it's only a decent romance story with almost no drama but relationships built upon onsen service and sex (education). Truth be told, it's quite heartwarming.

Except for the main couple, all the other characters are really shallow. Instead of Koibana Onsen, this manga should be called geisha onsen or borderline prostitution onsen. By borderline prostitution, the staff members give "service" to bachelor customers. Wink wink. Hence, a lot of characters in this manga are quite shallow. Only the main couple felt like they ever had true romance. The side characters' romances just felt like their relationships were built upon pure lust rather than love/emotions.

It's a light and silly read but there were a lot of questionable forced oral sex situations (almost rapey due to many of the side characters' lack of willpower to reject advances).

If this story was mainly focused on the main couple, I would've given it a 9. However, halfway through the series, the main couple becomes sidelined and the side characters become the main focus, which was boring if you didn't care for the shallow side characters. Literally the last 4 volumes of the series focus on the side characters. I only forced myself to finish this series because I wanted to know the ending for the main couple. Overall, it's a 7.
