STACEY VANEK SMITH: Toyota reported a massive hit to production following the earthquake. The Japanese carmaker said today output plunged 30 percent. Honda's output has been cut in half.

It was a tough quarter for another Japanese company as well. Nintendo reported profits down 66 percent -- the game-console maker wasn't hurt directly by the earthquake but has been hit by some new competition.

From Tokyo, here's the BBC's Roland Buerk.

ROLAND BUERK: Nintendo needs to power up its slumping sales. In its earnings report, the company reports says profits have fallen by two-thirds in the past year. Plus there's the looming threat of smart phones which offer much cheaper, more portable games.

Jay Defibaugh is an analyst with MF Global.

JAY DEFIBAUGH: It's an issue for Nintendo as well as Microsoft and Sony -- the idea that you can buy a quality game for $1, or $2, or $5. Versus what Sony, and Microsoft and Nintendo would rather have you do -- buy something for $40 or $50 or $60.

Nintendo says one way it hopes to stay ahead of the competition is with the first handheld 3D device you don't need 3D glasses to use -- the 3DS. The device went on sale late in February, so we won't find out how well that's been doing until Nintendo's next profit report.
