So, this is apparently another optical reconnaissance satellite of the same make/model as IGS Optical-5?

(forum launch thread here)

Do our reconnaissance satellite experts have any idea which IGS satellites, optical and radar, are (probably) functional?

For what it's worth, there is a Wikipedia list that gives current status:

FWIW, the local weather forecast for Feb. 25 shows thunderstorms at launch time with rain continuing into the 26th. Expect the launch date to slip 1-2 days.

As of Sept 15, 2017 there were "6 [operational] Japanese IGS orbiting the Earth"

As you mentionned, these 6 should be: Optical 4, 5 and Radar 3, 4, Spare, 5

People visiting the island are currently waiting for the rollout to occur (the exact time is classified  ;)), which should happen over the next few hours.
