We have about 1,400 repeaters throughout the country — hundreds of 70cm (430MHz) and 23cm (1200MHz), as well as about one hundred 13cm (2400MHz), eight 5cm (5600MHz) and five 3cm (10.1GHz).
We have NO other bands ones.
Recently, over 200 digital — aka D-STAR — repeaters are included on 70cm and 23cm.

The follows are special repeaters:
(1) ex-JP1YEX — the first trial repeater for digital communications in our past May 6, 1986 - May 6, 1988 (434.44MHz in/439.44MHz out).
(2) JP1YIV, JP1YLO and JP3YIT — for the D-STAR verification testing,
(3) JP1YJJ — for Hamfair.
Repeaters' call signs are allocated as
JR#WA-WZ, JR#VA-VZ and JP#YAA-YZZ in mainland — including Ogasawasa —,
while JR6YA-YZ and JQ6YAA-YZZ for Okinawa.
But blocks JP#YAA-YBZ and JQ6YAA-YAZ are withheld.
