Kenshin and Inuyasha belong to an ancient japan. Both use swords, and both have two girls!! One of the past, and one of the present. Both have also a similar quantity of main characters.
Inuyasha and Kenshin share a lot of qualities, especially considering the 'feel' or 'mood' of the series. Where one is set in Meiji era, the other takes place in a fantastical alternate world, however both concentrate on fighting on the canvas of more light-hearted slice of life (which occasionally goes into deeper, darker drama) comedy and romance.
All in all, if you watched one and want more of that feeling you had while watching, the other if the first place you ought to visit.
