This is a lovely gesture for the people of Japan from the two Kings of Berlin. But I can't help noting with an ever-so-slight feeling of hilarity how Rattle looks like he's giving Barenboim a death-look. Rattle, with his schlecht deutsch, is clearly reading from a teleprompter. Barenboim, for all we know, might have also been instructed to read from the teleprompter but instead decided to pull a Kanye and improvise without telling anyone. That's pure speculation on my part and I'm probably just fantasizing. All things considered, it's an extremely meaningful gesture from two musical giants who have made an enormous effort to show how well they get along even though a rivalry between them could have been the most natural thing in the world.
