Female at Taiji Whale Museum:

Right after the capture Taiji Whale Museum submitted a research proposal (which should have been submitted prior to getting an approval for the capture), and promptly started its interspecies interaction research program in April in 1997. The female orca was put into a tank with other dolphins such as false killer whales, pacific white-sided dolphin and bottle-nosed dolphin.

In 2003, it was loaned to Port of Nagoya Aquarium under a breeding program. (Please refer to About Port of Nagoya Aquarium for more detail about this.)
Died as the last of the captive orcas at 7:55AM(JST), September 19th 2008

Three orcas at Adventure World:

9On June 17th 1997, the pregnant female died at the aquarium. It was reported at the same time that the young male calf that was reported to be healthy through the Fisheries Agency had also died three days before on June 14th. The female did not eat, and since she had the miscarriage in April her health deteriorated significantly, unable to swim or float on its own. She was held at the surface with a tanker and was force-fed liquid food by the aquarium staff, later an inside source leaked.

Tissues of the dead orca were sent to Wakayama Medical University for autopsy. The preliminary report submitted at the end of the month showed that the young calf died from cytomegalovirus infection on entire body. The female died from bacterial suppurative pneumonia. It reported that a great number of bacteria infested the lungs, and when the energy and the immunity were low, the orca mistakenly drank some pool water, resulting in the multiplying of bacteria triggering pneumonia.

The pregnancy of the female orca was denied by the veterinarian at the autopsy (even though at the time of the capture the inside source leaked this information), no reports came out about the pregnancy and the miscarriage.

Data at the time of death:
- Male calf Body length 3.77m, weight 650kg
(Body length 3.75m and weight 700kg at the time of capture)

- Feale Body length 6.4m, weight 3,000kg*
(Body lengh 6.30m and weight 5,500kg* at the time of capture)
*: Depends on Data from Fishery Agency.

The remaining one male orca ,"Q-chan" was kept isolated by itself under a strict regulation of tank environment, and debut in orca performance show in 1999, but it died in 2004.

Female at Izumito Sea Paradise:

The female later named by the staff "Asuka" was initially brought in to be a breeding partner for the already residing male "Yamato" an orca captured in Iceland, trained in France, and brought into Japan in 1995.

In 2000, Yamato died, and the breeding program failed.
Asuka also died in 2007.
