7J — Foreigners who established their stations 1985-1999

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.

Exception — 7J1RL

7K-7N — Call Sign Shortage in Area 1

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).

8J — Special Event Stations

Prefix 8J is normally used for special event stations and for ARISS school conatact temporary stations. According to the reslt 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:

8M — Special Event Stations, for a suffix alignment

Prefix 8M was exceptionally used only twice, to align a suffix among three stations for a same event.

• 8M2000
  with 8J2000 and 8N2000, all for AD2000 memorial.
• 8M1C
  with 8J1C and 8N1C, all for FIFA World Cup 2002.

8N — Special Event Stations, originally under either of two conditions

Prefix 8N has gradually become popular for special event and ARISS school contact stations. Originally, 2001 and before, it had 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.

Foreigners Operable

Before the appearance of the 8N prefix, we had 8J1WJ and 8J3ITU as foreigners operable special event stations.
After the clearing away of the difference between 8J and 8N, 8J2AI is becoming foreigners operable in 2005. In addition, 8J1XPO in 1985 was also a foreigners operable even its 8J prefix.

In Okinawa

Even in this era (1991-2001), prefix 8N6 is not mandatory for Okinawa. In fact, 8J6SMT and 8J6FTY existed in this region in 2000 and 2001 respectively.

Exception — 8N2000
