Kimi no Iru Machi: Tasogare Kousaten

Without the real drama, kimi no iru machi is the little brother of 5 centimeters/secs  

While the manga version of Kimi no Iru Machi is unlike 5cm Per Second, the anime version is. Both construct a romance that is present despite a large separation between the two protagonists. The story-telling is also similar between the two; both anime titles tell their respective stories out of order. While Kimi no Iru Machi is a bit more light hearted than 5 cm Per Second, it has the same dark underlying tone. Finally, the music of Kimi no Iru Machi and 5cm Per Second both involve a beautiful piano piece that creates a very enriching atmosphere for the respective series. 

These are two short anime that show the difficulties of maintaining a long-distance relationship. Male and female leads inevitably become distant to each other because of the distance in their living quarters. Both have a bitter-sweet feel. 

Both have similar long distance relationships and drama. The backgrounds, especially with the trains and subway stations, look very similar. Both are about an hour long in total. 

These two animes shares a similarity of a story between one couple who faces the difficulty of a long distance relationship. Both animes last for only about an hour in total
