The 12 Japan pro baseball teams opened their 2007 spring camps on Thursday. By rule, players are not allowed to work out in uniform until that date and, unlike major leaguers getting ready to go to Florida and Arizona, all the Central and Pacific League clubs break camp on the same day.

Everybody -- pitchers, catchers and fielders -- starts at the same time.

Daily sessions usually begin at 9:30 a.m. with players stretching, running a few laps around the field and playing catch.
