Postal stationery from Japan can be classified in two types:

POSTAL CARDS WITH ADVERTISMENT:

They are either called “Kokoku - Tsuki - Yubin - Hagaki” (= Advertisment - with - postal - card) or “Echo Hagaki” (= Echo postal card).
An advertisment is printed at the bottom of the postcard and the sponsor must obtain authorization from the Ministry of Post and Telecommunication.
The official notice was revised on Oct 1st, 1988: Echo postal cards can be issued when the number issued is higher than 49 999.
The advertisment fee is as follows:

number issued cost / unit
50 000 - 99 999 11 Yen
100 000 - 2 999 999 10 Yen
3 000 000 - 6 999 999 9 Yen
20 000 000 8 Yen

 ILLUSTRATED POSTCARDS:

They are either called “Eiri - Kansei - Hagaki” (= Illustrated - government-printed - postcard) or “Eiri - Kanyo” (= Illustrated - government-printed - postcard), with “Kanyo” being an abbreviation for “Kansei - Hagaki”.
The illustrations are just overprinted on normal postcards. That is why these cards are called “illustrated on government-printed postcards”. The sponsor does NOT need permission when issuing this kind of postcards, that is why there is very little information available on them.
