How to use

For now, just list:

$ prefecture 
Hokkaido
Aomori Prefecture
(Abbreviation)
Kagoshima prefecture
Okinawa Prefecture

Separated by commas:

$ prefecture -f "%s,"
Hokkaido,
Aomori Prefecture,
(Abbreviation)
Kagoshima prefecture,
Okinawa Prefecture,

Separate with commas and put out in one line:

$ prefecture -f "%s," --no-line-break
Hokkaido,Aomori Prefecture,...,Kagoshima prefecture,Okinawa Prefecture,

Enclose in quotes and put out with commas:

$ prefecture -f "'%s',"
'Hokkaido',
'Aomori Prefecture',
(Abbreviation)
'Kagoshima prefecture',
'Okinawa Prefecture',
