The Nippon Ham Fighters Fan Support Group apparently placed a call for fan mail addressed to Yuki Saito and received about 870 letters. The group plans to present all the letters to Saito on Thursday.
Sanspo notes that large percent of the letters also were in favor of keeping Saito's nickname as Yu-chan.
Saito arrived at New Chitose Airport after 10am this morning. With him were his father and a Nippon Ham Fighters scout. About 200 reporters and 300 fans showed up at the airport to see Saito. Saito flew in an ANA airplane that had images of Pokemon on the side (there's apparently only one of these planes in service right now). He also sat in the premium class.
The Fighters will be giving Saito a tour of some of the more famous places in Sapporo, like the Clock Tower and Odori Park, before and after today's press conference. It'll be the first time Saito steps foot in Sapporo.
