Rossi had called the bend where Kato crashed "too dangerous" over the weekend.
The Italian said after the race: "[The win] is special for Honda and 25 points for me at the beginning of the championship is important. But after hearing about Kato nothing is very important.
"The victory means nothing at the moment and all our thoughts are with Kato-san."
