Can robots save an aging Japan?

Can robots save an aging Japan? A mechanical wolf robot used to ward off bears and wild boars at a cabbage farm in the village of Shimo Higashiyama, in Yamagata Prefecture. It's hard to explain why Japanese love the cherry blossoms, called sakura. Robots do not appreciate the soft evanescence of the sakura. Nor do they understand why a snowbound town in northern Japan has dedicated itself to the cultivation of a winter variety. But the residents of Nishikawa have discovered -- at least, they thought they had discovered -- that they need robots for their sakura.
