But why did he choose 4 months after the explosion?

He didn't, hence the "was I really gone for that long?"... He's got his teleportation and time-stopping thing down, but apparently he still needs some working on his aim when time travelling...
I think it's just a trick by the writers to make the story easier to film and understand.
Imagine if we had to watch Hiro's story in feudal Japan, and at the same time watch him back in present time after all his adventures. They logically should have made the whole first episode and a half about JUST Hiro in the past, and then have him back in present time so as not to show him in two different timelines at once. But they didn't because that would have been boring and they would have lost some viewers. They had to develop the other storylines as Hiro was back in time.
So, when he finally came back, he came back at the point where we were as viewers, and this cannot be explained by any intratextual rule (meaning any logic found within the show), it can only be explained by the limits of the medium they are using, television. Because realistically, Hiro would have indeed teleported back to the exact moment he left. Him not knowing at what moment he teleported back doesn't make sense, especially after seeing how much mastery he has gained over his power, judging from his ease at teleporting anywhere in feudal Japan (i.e. bringing Kensei to the angry Ronin at the right place and the right moment). But Heroes is a TV show, and this means that it is not only guided (or restricted) by the logic of its fictional universe, but also by production issues, marketing preoccupations, actor availability, etc.
