Just finished this and I must say, it's one of the best dramas I've watched so far.
And the fact that it's a story of real people real events, makes it even more gratifying.
Takeru Sato's acting is superb, he's truly talented. His chemistry with Kuroki Haru is also wonderful, but then again, he always hits it off with whoever paired with him.
Watching this makes me understand the Japanese people love for their Emperor and the Imperial family - liken it to miso, is probably very fitting.
Must watch. You won't regret it.
