Statement Concerning Tanaka

Dr. Tanaka- in anatomy, not with Ishiyama.

During 1945 at the anatomy department there were only Hirako, Ishisawa, and assistant professor Katsumi Tanaka.

During 1945 Hirako, assisted by Asst. Prof. Katsuni Tanaka and Asst. Kaneo Kida taught dissection.

In Feb. or Mar. 1946 Ishisawa called Tanaka to his office, who said that he didn't know about the actual operations, but that under Hirako's directions after the operation, he had helped to clean up. To "clean up" means putting the remains in the wooden boxes and taking them to the crematory.

Katsumi Tanaka was an assistant professor in the anatomy section.

When Makino left KIU in June 1945, he made up a list of specimens of the human anatomy which he wanted to take with him, showed it to Tanaka, Ishisawa and Hirako, and they all said it was all right.

In addition Makino took another group of specimens. Makino told Tanaka that he was taking these too. (These are evidently in addition to the list that he requested.)

About 12 May 1945 Tanaka told Makino that Hirako had said Ishiyama was going to do an operation on an American PW who was hurt, and that the operation was to be held in the Autopsy Room of the Anatomy Department. (Makino went to Yonago 20 May and it was about a week before the Tanaka told him of the operation.)

1-2 days later, at lunch, Tanaka told Makino that the operation would be held that day.

Tanaka arrived, said, "It is about time for the Prisoners to arrive. Let's go and see." This was about 1330 or 1400.

Makino then (after arrival of PWs) went back to his room, Left Tanaka watching the doorway, who joined him in Makino's room a few minutes later. Makino stayed in the lab for about 30-40 minutes. Tanaka was in and out during this time.

In Autopsy Room during operation, Tanaka was standing behind the members of the Ishiyama Clinic.

Just before Makino left, he saw Tanaka walk around and stand behind Ishiyama.

Makino did not see Tanaka after the first time he was in the operating room. Tanaka had also told Makino that Hirako had told him that if the Prisoner died he wanted the brain.

Makino then adds the following: About 1630 Tanaka came back to the lab from seeing his wife in the maternity hospital, and said that Hirako had told him that the Prisoner had died from the operation and that if Makino wanted any specimens from the body for histology research to take them. Tanaka then took some small bottles for specimens and made up some Zenker solution; placed all the bottles on a tray and walked out. Before this Makino had filled 3 small bottles, of 50 cc each, with formaldehyde and placed them in the tray that Tanaka was carrying, followed Tanaka out of the lab.

Tanaka and Makino went directly to the Autopsy Room to get their histology specimens. Tanaka took parts from the small intestines, large intestines, stomach, supra renal gland, and kidney. There was a small part of the liver left; Makino believes he also took that.

Goshima then cut a part from the lower part of the heart with his scissors and held it in his hand. He then cut it in smaller pieces and put half of them in Tanaka's bottle of formaldehyde solution.

Ryu then asked Tanaka if he were finished, and Tanaka stated, "Can you take part of the lung out?" turning to Goshima, who thereupon reached into the chest incision with his pincers and probed toward the left lung. He got hold of something and then reached in with his scissors and snipped off a specimen and gave it to Tanaka who held out his bottle of formaldehyde solution.

Tanaka then said, 'We've finished; let's go." So they left. Tanaka walked down the hall toward his lab with the tray of specimens; Makino went to the servants quarters to get hot water to wash his hands.

Tanaka had held a prt of the small intestines with one pair of pincers; Makino took another pair and held down the other small intestines so Tanaka could cut off the specimen.

When Tanaka came and told Makino that Hirako had said the Prisoner was dead from the operation so they could take what specimens they wanted, Makino told Tanaka that he wanted some also. It was then that they made their preparations. Makino told Tanaka that he wanted specimens, but he didn't carry any bottles of solution to the Autopsy Room, didn't take any specimens from the body himself because he knew that he could ask Tanaka for any specimens needed.

When Goshima took the specimens from the heart and lung, he first gave them to Makino, and Makino gave them to Tanaka. It was when Makino was explaining the parts of the heart that Tanaka asked for a specimen and Goshima then cut it off.

Makino then remembers that when Tanaka took the specimen from the stomach Makino helped him by pulling out the stomach with the pincers while he cut the specimen. That when Tanaka cut out the supra renal gland and the kidney, Makino held back the opeing of the incision and pushed the intestines away so Tanaka could get at it.

Goshima and Ryu had started to remove the brain when Tanaka and Makino left.

Makino then went to his lab, found a bottle of formaldehyde with the larger tagged specimens which Tanaka had taken from the Prisoners body on his table. The smaller specimens in Zenker Solution were also there. Makino went home.

2-3 days later, about 1400 Tanaka came in, said, "It seems as though Ishiyama will perform another operation today."

Tanaka left and in about 20 minutes Makino decided to go.

Makino walked to where Tanaka was standing-- about 4-5 feet from the foot of the table. Tanaka had told Makino this was to be a liver operation.

Tanaka then asked the man who was making the injection if it were Ringers Solution, and he replied that it was not, but was seawater. Tanaka seemed surprised, asked how it was made, and the man replied "We filtrate the sea water," then said that it was diluted with water. Tanaka then asked him if they had been using this before, and he replied, "We have been doing this in our laboratory."

Makino left, telling Tanaka that he was going to the Rail Road Station.

Tanaka must have followed Makino to his room since he stuck his head in the door, said he was going home.

Makino met Tanaka in the student's autopsy training room next to where the operation was going on. Tanaka had some small glass bottles on a tray, said "We will get some more specimens, so bring a bottle of formaldehyde." Makino returned with the bottle, and they walked into the other autopsy room, noticed the liver operation was still going on.

When Tanaka and Makino arrived at the table in the far right corner, Mori and Hirao were operating on another Prisoner. (Heart operation)

Komori came back to the table, and, after looking inside the incision, looked at Tanaka and Makino and said "If you guys(??) want more specimens, it's all right to take them.

Shortly after Makino arrived at table where Mori and Hirao were operating, Makino saw Tanaka walking out. Makino doesn't know whether he was at the 2nd table with him or not. Makino stayed there until Mori made the incision in the chest over the heart, then walked out. He then met Tanaka, in the adjoining autopsy room, when Tanaka told him to get the formaldehyde. When Makino arrived back where he had left Tanaka, they walked to the operating room together. Tanaka placed his tray on the edge of the clean up tank and walked toward the exit to the hall.

While Komori had the liver in his hand, Tanaka came to the table. Komori began retracting the neck incision himself, and then Tanaka again walked away. Komori asked (Tanaka came back again and said that he wanted more specimens that they did not get the last time) Tanaka if they wanted them for the students' histology class. Tanaka said yes, walked away again. Komori then said, "Well, if that is the case, bring your jar of formaldehyde and I will take out the specimens for you." Komori took small specimens from the trachea, larynx and the thyroid gland, and placed them in the bottle of formaldehyde.

Tanaka then came to the table, said that he would now take some specimens also. Komori had just left before Tanaka arrived at the table. Tanaka then started to take his specimens, also took parts of the thyroid gland and trachea. He then made an incision in the testicle sack over the left testicle, exposing the testicle. He cut off the bottom half of the specimen, and then he cut that piece in half again. He placed half in his bottle of Zenker solution and then cut the other piece in half and placed half in Bouin solution and the rest in Makino's bottle of formaldehyde which Makino brought him.

Makino then left; Tanaka stayed in the autopsy room.

After lung operation Goshima went to dissecting room and saw body of Prisoner. No one was there at that time. Goshima then returned to his lab to get instruments for removing the brain of the dead Pris ner. He gathered his knives and returned to the autopsy room where the dead body was lying on the dissecting table. Goshima was still alone, but when he re-entered, Tanaka was at the table, working on the dead Prisoner's body, taking out specimens, was alone.

Goshima had to make several trips to bring equipment, and by the time he had brought it all, Makino had joined Tanaka, and they were busy working and talking, and Goshima went back to his lab to prepare some Meuller's solution. Tanaka and Makino were still removing specimens from the stomach and chest cavities, seemed to be working together.

After Ryu and Goshima made the Meuller' s Injection, Makino and Tanaka left.

Goshima did not help Tanaka or Makino take any of their specimens, did not reach into incision with Makino and take the Prisoner's hear in his hand, did not cut specimens.

At about 1700, Ryu heard the doctors leaving, and a few minutes later Goshima left the lab taking surgery knives, scissors, a saw, and injection equipment with him. (This was after the lung operation) Ryu followed a few seconds later and went to the autopsy room, saw the body of the Prisoner from whom Ishiyama had removed the lung still on the dissecting table, with no clothes. Tanaka, Makino and Goshima were at the table. Tanaka was working in the stomach cavity, and he cut small specimens from the organs. He tagged each specimen and placed it in a bottle. Makino was putting tags on specimens and helping Tanaka. He was holding the incision open and holding the intestines and other organs aside so Tanaka could cut out the specimens.

Goshima made an incision on the dead Prisoner's neck, exposing the veins. They could not locate the artery, so they asked Tanaka, and he showed them where it was. Ryu believes Makino and Tanaka had left after Goshima and Ryu started to inject the solution.
