Questions about example sentences with, and the definition and usage of "Hapa"

Q: Congratulations to all Hapa buddies on the 500 days of journaling. I joined this group in April the year before last. I believed Jun-san’s word "Journaling is something that I think really, really works with every single student whether they are beginner level or advanced level. So just take my word for it and try to keep journaling only for ten days." Even though I had never written a diary in Japanese, I started journaling in English. It has been almost two years since then. Time flies so fast. I'm patting myself on the back. I’m certain that journaling is a stepping stone to master English. I can never thank Jun-san enough. soa natural?
