If you liked the Umisho anime, the Anime-Planet community thinks you'd like:
The Kawahira family specializes in dealing with troublesome spirits with the help of inukami, strong dog spirits that take human form. Members of the family are expected to make pacts with strong inukami in order to fulfill their duties, but their family has a black sheep: the perverted Keita, who charges people for his help. His inukami, Youko, is dedicated to make Keita completely hers. Her favorite form of punishment for him when he strays is teleporting him into the city completely naked. He's been arrested for indecent exposure so many times that he's a jailhouse regular, and is considered an outcast by his family and normal society; yet an inukami of the highest caliber chose to be his partner?! Is there really more to him than perverseness?
Both of these series have a great sense of humor and a similar one at that. Despite the differences in actual character motivation, where Umisho is about swimming and Inukami is about obliterating evil, they find similar ways to be silly and use sexuallity to build the humor factor.
Although i found Inukami! to be three times funnier as well as having a much more elaborate plot, the humor is similar. While i couldnt stop laughing at Keita in Inukami, i couldnt stop smiling at Amuro in Umisho because of her adorable nature.
What if roller skates had high power engines that enabled the skaters to do stunning new tricks that defy gravity? What if you saw a beautiful girl effortlessly glide through the air with them? To Ikki, this is reason enough to secretly borrow a pair of Air Treck skates, and step into an underground world filled with gang fights and strange customs. Enamored with high-flying stunts and the flirtatious Simca, Ikki forms an Air Treck gang of his own and starts a life of fighting rival gangs and flying over the rooftops, chasing the girl always one kick ahead of him.
The main theme in these anime is sport: umisho has swimming and air gear has rollerscating. These anime also both have some ecchi scenes like panty flashes. Comedy and friends are also some important themes these anime share.
Kojirou-sensei, the rather indifferent teacher and coach of the school kendo club, is in financial dire straits. As a result, he makes a bet with his fellow kendo coach and former upperclassman to see who can assemble and train the better female kendo team, with the prize for Kojirou being a year's supply of food if he wins. Motivated by the idea of free food for a year, he begins to teach the club seriously; however, most of its members have already graduated, and so he is tasked with assembling members in addition to training them for the competition with his rival. While dealing with his eccentric students, he slowly rediscovers why he loves kendo and what it truly means to be a teacher.
There are a lot of similiarites between Bamboo Blade and Umishou, so it's no wonder that they both invoke the same sense of feeling and atmosphere while you're watching the two works.
If you like the light-hearted and comedic nature of one show then you'll definitely like the other show for the exact same reason.
Both works are also based around high school sports club (swimming in Umishou and Kendo in Bamboo Blade) who naturally compete in various tournaments and matches.
Winning a game of Mahjong is hard; getting the same score every time is practically impossible. So imagine the surprise of the school Mahjong club when Saki Miyanaga walks in and does just that. Despite her dislike for the game, her talent is obvious and it's up to the club members - the top-heavy Nodoka, the energetic Yuuki, the cunning Mako and the permanently in control club president Hisa - to persuade her to join the club and help them reach the Nationals. But even then, will their combined skills be enough to overturn some of the toughest high school players the country has to offer?
Umisho and Saki are anime best of Sports+Moe comedy+Fan service combination. Umisho is bigger on fanservice but Saki don't lose with its lesbian and nopan innuendo. They both can boast by great collections of funny, sexy and likable characters. Also they have some sport competition somwhere in there.
While visiting his hometown, junior high school student Michishio Nagasumi's life was changed forever when he nearly drowned. Though he was saved by a mermaid named San, there’s a catch -- her family is part of a merfolk mafia, and they abide by a strict rule: If a mermaid is discovered by a man, either he or the mermaid must die. That is, unless the man marries into the family! Faced with such a decision, Nagasumi can only oblige their customs and become a "happy" newlywed. Now, with a new school year around the corner, Nagasumi must find a way to deal with his new bride, keep her true nature a secret, and most importantly, escape inevitable death at the hands of San's over-protective father’s gang!
Both of these anime series have some a similiar styling. The introduction of a drowning male character saved by a "Mermaid". The annoying rich third party girl who tries to take center stage. The socially imcompetent companions of the main main character. The oddball main female character who confuses everyone because she's different. Although Seto no Hanayome was more slapstick comedy and Umisho was more ecchi, both seem connect together on many things.
