Yahoo Japan has ditched Sony and chosen iTunes to act as the music store of choice for its operations there, reports MacWorld.

The partnership will put a sizable link to the iTunes Store in the place of the link to Mora, a music store maintained by Sony.

Mora will still be an option, but iTunes will be the default store. The deal gives iTunes a significant leg up on the Japanese market, since Yahoo reaches about 84 percent of of the country's population.
