A 7J-8N amateur call sign implies
The following is not a written policy, but a follow-up categorization by the author. (8K and 8L are not used yet.)

Prefix 7J is for foreign amateurs who reside in Japan under reciprocal permit since Sept. 17, 1985.
But on May 28, 1999, the Japanese authority has announced that, for non-Japanese, they will start to use the same call sign series as the Japanese. No discriminations any more. (But maybe 7J's sound better....) So the 7J prefix will not be issued any more, while existing stations can continue to use their original 7J call signs (in addition, an old holder can bring back his/her expired 7J call sign). They were issued sequentially from 7J#AAA, while 7J6C$$ means 7J's in Okinawa (normally US military). A club station having a foreigner representative which the authority granted since 1993 uses the 7J#Y$$ block.

*: Actually, "Ogasawara EME Club," 7J1YAM existed in Ogasawara, Aug. 25 - 28, 1998.
159 individuals and 23 clubs still remain (as of Mar. 12, 2011).
Prefixes 7K1-7N1, 7K2-7N2, 7K3-7N3 and 7K4-7N4 were issued during the call sign shortage era Apr. 23, 1990 - June 20, 2003 for Area 1 (i.e. Not for Area 2, 3 and 4).
Prefix 8J is normally used for special event stations and for ARISS school conatact temporary stations. According to the result of WRC-03 — in Japan, applied on June 24, 2004 — the MIC permitted the applicant to select the any of from "single-" to "five-character" suffix as 8J#$, 8J#*$, 8J#**$, 8J#***$, 8J#****$; 8N#$, 8N#*$, 8N#**$, 8N#***$ or 8N#****$, under the following conditions:
|Call Sign||Event||Year||Actual Call Area|
|8J1WJ||The 13th Boy Scouts World Jamboree||1971||2|
|8J90XPO||The International Garden and Greenery Expo||1990||3|
|8M1C||FIFA World Cup, Yokohama||2002||1|
|8N23WSJ||The 23rd Boy Scouts World Jamboree||2015||4|
8J1WJ was directly licensed by the Ministry (not by a branch) and was the very first 8J station in Japan's mainland — i.e. except Antarctica. It might be there was no call area concept for a special-event station yet, in such ancient days.
During the aftermath of Kobe earthquake which occured on Jan. 17, 1995, the JARL and the Japan Amateur Radio Industries Association (JAIA) conducted the effort at the request of the Ministry of Posts and Telecommunications (now "the Ministry of Internal Affairs and Communications"). JAIA member companies supplied two hundreds (200) hand-held transceivers, followed by additional sixty (60) ones, for 430 and 1260 MHz for the operation. The Ministry orally licensed each of them and assigned a special call sign 8J3AAA, 8J3AAB and so on. All licensees are the JARL.
During the aftermath of Tohoku-Kanto earthquake which occured on Mar. 11, 2011, JAIA supplied two hundreds (200) Icom handy transceivers. Vertex Standard and Alinco, which are both JAIA non-members, also responded with fifty (50) tranceivers each. The Ministry assigned them a special call sign 8J1QAA, 8J1QAB and so on. Though the quake occured at Area 7 offshore, the Kanto (Area 1) Bureau licensed them, on behalf of busy Tohoku Bureau. All licensees are the JARL.
Prefix 8M was exceptionally used only twice, to align a suffix among three stations for a same event.
Prefix 8N gradually became popular for special event and ARISS school contact stations. Originally, 2001 and before, it meant, but not mandatorily, a special event station (1) having availability to be operated by foreign amateurs without any reciprocal permit, or (2) locating in Okinawa as 8N6. Having been cleared away such special meanings, nowadays an applicant can select either 8J or 8N without any distinction — nevertheless it would be fact that 8N still implies that "more special than 8J" for us.
Before the first ever appearance of an 8N prefix in 8N1WCY in 1983, we had 8J1WJ and 8J3ITU as foreigners operable special event stations.
After the clearing away of the difference between 8J and 8N, 8J2AI became foreigners operable in 2005. In addition, 8J1XPO in 1985 was also a foreigners operable even its 8J prefix.
Even in this era, prefix 8N6 is not mandatory for Okinawa. In fact, 8J6SMT and 8J6FTY existed in this region in 2000 and 2001 respectively.
