I'll keep this updated throughout the day.
An 11-year-old boy, named Masaki Yamamoto (山本雅樹), was given the chance to throw out the ceremonial first pitch before today's game against the Hanshin Tigers. Yamamoto is a earthquake / tsunami survivor from Fukushima.
Yamamoto - "This was the first time I've been to Tokyo Dome and I was able to throw the ball as I had hoped, even though the crowd was loud and I was nervous. It's frustrating / saddening that I can't play baseball as usual anymore because of the earthquakes. Today, I did just as my father and mother said: I threw the ball as hard as I could while thinking about living in relief shelters while not being able to play baseball. My dream is to become a Giant. I was also able to get an autographed ball from [Shun] Tono and it will be a prized possession.
The Lions ended up having to turn on extra lights (from 33% to 66%) during today's game (in the top of the 6th). The umps requested the change in order to ensure fan and player safety (the ball was hard to see and overcast weather wasn't making things any easier).
The Eagles have decided to invite 100 earthquake / tsunami victims to a game on the 8th (vs Seibu at Kleenex Stadium). The Eagle Rainbow uniforms will also be auctioned off, with all proceeds going toward helping children orphaned by the March 11 earthquakes.
The linked to article also mentions that of the over 100 sponsors the Eagles have, none canceled their contracts because of the earthquakes and a number of sponsors actually offered to pay more in order to help out.
