Honestly, I don't know why i read this. This is a mediocre manga. I have made many life choices that i have questioned with scepticism.This is one. This has no real storyline, Just an excessively spread out plot. This is conducive to suicide. Why you might ask, well that is because of the poor sex scenes. Either label it a hentai, or steer clear of that area. It may be different strokes for different folks, but the cynicism in me says otherwise. Also where is the message to be found? Is it the relationships deepen after excessive amount of sexual intercourse? No not in read more

Koibana Onsen is a manga that requires a bit of caution before venturing into it, due to its mature sexual content. But with that said, Koibana Onsen is something I could - maybe not wholeheartedly - recommend for those looking for something a bit more raunchy than ecchi, as this is a fairly decent Romantic, Harem.

Welcome to Koibana Onsen, the place where love blooms. A family-run Inn, within a secluded rural setting, provides a unique romantic atmosphere for the couples that use it for their little romantic gateways. So it was quite the surprise when Akiyama, rather than cancel his reservation, decided to go to read more

*Please beware of this manga mature sexual content*

Koibana Onsen, the place where love blossom, is a family run-inn by 3 sisters. To no surprise, it is a perfect atmosphere for a couple who just want to escape the world and express their love. It is filled with beautiful scenery, delicious food, and wonderful open air baths that just make the perfect mood. However, one day Akiyama Kazuhiro, after being dumped by his girlfriend and feeling bad on cancelling the reservations arrives at the inn. This is the first time a customer has come in without a partner, so the 3 sisters decides that they will read more

This manga had no almost no story. It felt more like a short rather than a manga with its gimmick being the love onsen.

While reading the manga, I felt the author could have made it interesting but decided to ignore that and went on ahead to repeatedly write similar chapters with different characters. The manga has like 64 chapters, but when I finished I felt if I would have had to compare it to anything, it would be like watching Naruto and coming across many fillers.

- If you like greatly detailed drawings of penises and vagina's, this story isn't for you because the read more

Manga: Hetakoi
Hetakoi and Koibana Onsen is similar in two ways. First, there is a hot springs context which provides the circumstances for characters to meet and for relationships to develop. Second, there is emphasis on mature sexual relationships among characters that is profoundly built on many primitive emotions related to love and lust.

Manga: B Gata H Kei
Both are about romantic first love/ first sex.
The humor is sexual without being "dirty" I guess you would call it
B Gata has nudity and sexual content, be advised that Koibana has a WHOLE LOT MORE, it is borderline Hentai.
They both left me feeling happy with good endings.

Manga: Haru yo, Koi
Both we find our male protagonist in more than one mature relationship and his struggle in the matter of love. Koibana Onsen has an approach more love-like, Haru yo, Koi you find the male protagonist having an approach more sex-like "because" of love.

Manga: Love♡Lucky!
Both of these are happy romances with almost no drama whatsoever although the key similarity between the two is the fact that both blatantly deal with sex. Love Lucky! is a little bit less geared towards sex however in both manga their are numerous sex scenes. Also the personalities between both the male and female characters are extremely similar.

Manga: Futari Ecchi
Both deal with the relationship between sex, romance, and love; both focus on how the problems of young couples can affect their sex lives (and vice versa); both maintain a light, romantic tone, even while discussing serious issues. Both are borderline-H manga.
