In the city of Isahaya, which is a very hilly place, Kyushu in Nagasaki Prefecture in Japan becomes exciting for young people that are seeking things to do. Stay clear of the keisatsu by always riding your bike with a light after dark, then you can have lots of fun there.
Here is a dialectical Japanese grammar principle that I only heard in Isahaya, Japan
A super polite dialectical Japanese command form
nasai --> nshyai
So basically any verb in Base II + nasai Japanese Command form will suffice for this easy to convert Isahaya dialect.
1. ASOBI NI KINASAI!* - ASOBI NI KINSHAI!
"Come over and hang out again!", or
"Please visit us again!", or literally
"come and play!"
2. TABETE MINASAI!** = TABETE MINSHAI!
"Just eat it and see!"
Methinks that irrashai is part of this ancient Japanese language style
ASOBI NI OIDE* -
Tabete Goran nasai**
