Nagasarete Airantou

Nagasarete Airantou is probably the ecchi version of Seto no Hanayome. Pick up both if you love the perpetual thrill in hyper love comedy. 

at first main character comes to a place where isnt any men, only women and he gets chased there 

Both star the most unenviable male living in the most enviable scenario. These series are classic comedy-harem animes that will leave you wanting to watch them over and over again due to their witty slice-of-life scenarios and enjoyable cast of characters. 

how the main male character end up in an all-girl place. in IS: Infinite Startos Ichika is in an all-girl high school, but in Nagasarete Airantou Ikuto falls in an all-girl island. and how the main male character is skilled in a certain way of fighing, Ikuto is in swords-manship and Ichika is in the armor. and also, how the girls that like the main male character act similarly between the two animes, also how the main male character live with a girl  

both about some guy who winds up on an island with a bunch of girls 

Same idea, 1 guy, multiple girls that fall in love with him, although instead of an all girl's school, it's on an all girl's island. 

In each series, the protagonist is transported to an isolated, seemingly magical land, filled with beautiful women of similar apparent age filled with intelligent animals (In the case of Dog Days, many of these are anthropomorphized. In the case of Nagasarete Airantou, while they aren't anthropormophized, they can still talk). In each, despite the number of perfectly competent adults running around, children are left to make large decisions about the futures of their respective lands. While in Dog Days, there is at least one other male major character (Gaul), each story focuses on the way in which the protagonist interacts with the women around him and his surroundings and learns the nature of the land in which he's found himself, filled with light-hearted, mostly-harmless comedy. read more 

both are very very good slice of life and full of comedy .....well and also mikakunin has romance where nagasarete have harem-romance . 

both series are set at an island somewhere off japan. the difference though is that the island setting of kono aozora is more urban as opposed to the primitive island in nagasarete  

Girls.. Lots of cute girls... XoX This is great if you like to see girls have fun with other girls and has a lot of action mixed in. 

Slice of life, Romance, more characters , funny, and heartful ? 

Both are real funny and share similar characters. 

Comedy with young girls that all seem to like the main character. 

Similar story plot.... In nagasarete airantou, Ikuto was drifted to unknown Island and can't go back to his hometown,,, there he met Suzu and live together with her... In zero no tsukaima, Saito was drifted to other world and can't go back to his world... there he met Louise and also live together with her,, 

A clean start is always welcoming, whether it's due to family matters or other acts. 'Barakamon' has a slice of life setting that is both funny and refreshing to watch, it puts a smile on your face at moments when you least expect it. 'Nagasarete Airantou' puts the focal point on comedy and chick magnet, but still keeps the fun going with adequate character relationships along the way.  

Same thing., Boy gets stuck in an all girl area. Also some parts of showing how much difference there is in strength from the lead male. 

Both are Harem style animes, and both see the guy getting hopelessly out of his depth and needing the girls to save him all the time, I will say that the plot in R+V is a lot better than NA and more enjoyable, but NA has the edge on animation 

Both will keep you laughing. They both have harem and ecchi. Both main female characters are voiced by Yui Horie. OP and ED songs are also by Yui Horie. If you like Inukami! then I am sure you should also enjoy Nagasareta Airantou. Not always the other way around though.
