Takuma Sato's Indy 500 victory was big for a number of reasons: Not only did he avenge his 2012 loss–where he spun on the last lap trying to pass Dario Franchitti for the lead–he also became the first Japanese driver to ever win the race. Naturally, Japanese commentators from were quite excited at Sato's triumphant win.
The video above features the last five laps, but skip to 3:10 to hear the commentators become totally ecstatic as Sato rounds Turns 3 and 4 to victory. Contrast this with the reaction from Japanese announcers when victory at Indy slipped away from Sato back in 2012.
One can't help but watch this and think about Brazilian announcers calling F1 legend Ayrton Senna's victories with the same fervor. Check out this clip from Senna's 1991 Brazilian GP win, his first, to get an idea of what I mean.
You don't have to speak Japanese to understand the excitement these announcers feel as Sato crosses the line at Indy. Given that history was made, we think it's a totally appropriate reaction.
