The link you posted proves you wrong.
Hanaguma was wrong about being awarded two Bronze Stars though. He was only awarded one. Because it was awarded with the Combat "V" that is pretty good evidence.
He also was awarded the Combat Infantry Badge which is awarded for
Performing duties while personally present and under fire while serving in an assigned infantry, ranger or special forces capacity, in a unit of brigade, regimental, or smaller size, engaged in active ground combat
