Isn't this the one with Nanako Matsushima playing the aunt and Mao Inoue playing her daughter? The wiki.d-addicts site doesn't really give the names for the actors playing Seita or Setsuko.
My comments are gonna reflect the drama with Matsushima and Inoue. (you're gonna have to high light since it contains spoilers)
The drama seems to elaborate more on the anime, and I guess it made more sense as to why Seita had to protect his sister all the time. (I haven't watched the anime in a long time, and I doubt I have a copy around my house). In the anime, they focused more on the kids (obviously). In the drama, the aunt has three more kids. One has asthma, so whenever they get rations, the aunt would give more rice to her own kids rather than Seita and Setsuko (her nephew and niece). And Seita does sit around all day with Setsuko, you wonder why he won't work with his cousins until you remember that his father (Navy colonel) told him he better protect his mom and his sister. Personally, I thought that was stressed more in the drama than in the anime. I also felt really angry towards the aunt cuz she made a promise to her cousin (Seita and Setsuko's mom), but I guess a mom always feels like she has to take care of her kids first before other kids.Hmm, what else? I did cry while watching the drama, but not as much when I watched the anime. I guess I knew what to expect already. :dunno: But yeah, I recommend people to watch the drama if they've watched the anime.
The drama was done to commemorate the 60th year anniversary of the surrender/war or whatever.
