Many thanks for the coverage Steven and Rui.

Still the cubesats to be confirmed.

T+1:10:00 The last satellite, ALE 1, should be deploying now. Will have to wait for an official announcement before declaring success.

Mission success! Congratulations to JAXA for the successful launch!

The launch of the Epsilon Rocket No. 4 was successfully launched from the Uchinoura Space Observatory on Friday, January 18, with the first innovative satellite technology demonstration unit! Following the first compact demonstration satellite, we confirmed that all seven of Microdragon, Risesat, ALE-1, OrigamiSat-1, Aoba Velox-iv and Nexus were successfully separated.

Launch Success, The Innovative Satellite Technology Demonstoration-1 aboard Epsilon-4
January 18, 2019 (JST)

National Research and Development Agency Japan Aerospace Exploration Agency (JAXA)

National Research and Development Agency Japan Aerospace Exploration Agency (JAXA) launched the Innovative Satellite Technology Demonstration-1* aboard the fourth Epsilon Launch Vehicle (Epsilon-4) from the JAXA Uchinoura Space Center. The launch proceeded on time at 9:50:20 a.m., (Japan Standard Time, JST) January 18, 2019.
 The launch and flight of Epsilon-4 occurred nominally. All seven satellites separated from the launch vehicle successfully; the Rapid Innovative Payload Demonstration Satellite 1 (RAPIS-1) was jettisoned from the launch vehicle approximately 51 minutes 55 seconds into launch. Thereafter, other onboard satellites - MicroDragon, RISESAT, ALE-1, OrigamiSat-1, Aoba VELOX-IV and NEXUS - were respectively separated from Epsilon-4.

 JAXA appreciates all for the support shown in behalf of the Epsilon-4 launch.

*Innovative Satellite Technology Demonstoration-1 is a suit of seven small satellite missions to demonstrate innovative new technological approaches;
 - Rapid Innovative payload demonstration Satellite 1 (RAPIS-1), which JAXA developed with the assistance of startups
 - Small satellites: MicroDragon, RISESAT and ALE-1
 - CubeSats: OrigamiSat-1, Aoba VELOX-IV, NEXUS

At this time 7 objects (A to G) have been cataloged

Object A 's orbit:
2019-003A/43932 in 455 x526 km x 97.29°

JAXA received telemetry data from the Rapid Innovative Payload Demonstration Satellite 1 (RAPIS-1), launched aboard the fourth Epsilon Launch Vehicle (Epilon-4) earlier at 9:50 a.m. (Japan Standard Time, JST), January 18, 2019 from the JAXA Uchinoura
Space Center. The RAPIS-1 telemetry confirmed that the satellite's solar panels started generating electricity, which is essential for the RAPIS-1 operation. The telemetry also shows communication with the satellite via ground stations proceeded well.
This concludes the critical operations phase. *1

RAPIS-1 transitions to the in-orbit checkout phase. *2 During this phase of approximately 30 days, the functions of the satellite's onboard instruments will be evaluated.

JAXA conveys deep appreciation for the support by all for the satellite's launch and tracking.

*1: The critical operations phase: during this phase that follows the satellite's separation from the launch vehicle, the activities of the satellite's power and communication systems are verified. 

*2: In-orbit checkout phase: the status of the satellite's entire systems is examined throughout this phase.

Space-Track is characterizing it as a payload, but I will log it as a component rather than a payload in its own right. Orbit is 390 x 405 km;  ALE-1 is in 401 x 417 km. Similar DOM was flown on the Freedom cubesat and is illustrated here..

Space-Track has cataloged 2019-003K 53314 as 'ALE-DOM', the De-Orbit Mechanism from the Japanese ALE-1 satellite. As far as I know this is a deorbit sail (side length 1.5m) that was not meant to separate from ALE-1.

It is similar to @PWSat2 deorbit sail which successfully bring down satellite after mission ends.
