"SAN" is the most popular honorific used in Japan, mainly for human.
here in Kyoto and surrounding area, it is used a little differently.
for example, food.
just like Mr. & Mrs. Potato head, we call potato “OIMO SAN”
beans are called “OMAME SAN”
rice porridge is “OKAYU SAN” etc.
some say origin is language used among ladies-in-waiting who were working in imperial palace to distinguish the food for superiors from theirs. then it spread to civilians.
Shrines are called by its name or nickname + SAN.
Yasaka shrine is “YASAKA SAN”
Fushimi Inari is “OINARI SAN”
Kitano Tenmangu shrine is “TEN JIN SAN”
Some Buddhist temples are called like this, too.
TOJI temple is “KOBO SAN”
KIYOMIZU temple is KIYOMIZU san, etc.
Even Celestial bodies are called with honorific.
star is “OHOSI SAN”
moon is “OTUKI SAN”
and the sun is “OHI SAN”
and that was a little information for “YOSO SAN(non-locals).”
