Japan Blood Bank

The Japan Blood Bank is a successful postwar company that bought and sold blood, founded by Ryoichi Naito. Its public image as a charitable enterprise stands beside Kameya Sato’s account of Naito’s wartime scientific work in Manchukuo, including experiments on prisoners. The novel does not establish that the company itself conducted those wartime activities; instead, it uses the founder’s passage from a concealed past to postwar respectability to examine how institutions and individuals can prosper amid the selective recovery of history.

Corporate Identity and Public Image

The company enters the story through a newspaper article about Naito’s charitable work. Its brief description identifies it as a successful business that bought and sold blood, giving it a concrete commercial identity as well as a benevolent public profile. The article’s framing matters: it presents Naito as a figure associated with charity, while leaving his earlier career unmentioned. The contrast is not between two organizations, but between the reassuring public story attached to the founder and the wartime history that Kameya Sato recalls.

The evidence does not detail the Japan Blood Bank’s internal structure, its methods of collecting or distributing blood, or the scale of its operations. Nor does it say that the company used wartime research in its business. Its significance instead lies in the way its founder’s postwar standing becomes visible in the story: the organization is prosperous and publicly associated with charitable work, even as its past remains open to a radically different account.

The Wartime History Raised by Sato

The company’s public image is unsettled when Kameya Sato draws Tenji Nakamura’s attention to the article about Naito. Sato says that he had colleagues who worked with Naito in Manchukuo, where Naito was among the leaders of scientists involved in experiments on prisoners. Sato describes a broad operation supported at high levels, including testing biological weapons and other weapons on prisoners. These are Sato’s claims in the conversation; the narrative does not present an independent investigation of them or establish that the Japan Blood Bank participated in this work.

Sato also connects Naito’s respectable postwar reputation to a larger political silence. In his account, the Japanese government and the Americans had reasons not to expose the past: American interest in biological-warfare research, and the prospect of using such knowledge in later conflicts, helped make cooperation more important than public reckoning. He argues that punishment after the war was uneven, with some people executed while others escaped scrutiny. The company’s name thus appears within a dispute about who is held responsible, whose past is allowed to fade, and how practical political interests can shelter prominent figures.

Tenji Nakamura responds that the Japanese, too, were victims of the war. His statement does not answer Sato’s allegations about Naito; it reveals Nakamura’s own persistent tendency to understand himself, his country, and even executed comrades through the language of victimhood. The exchange makes the Blood Bank more than a setting for employment. Its public respectability becomes the occasion for a confrontation between an account that exposes wartime culpability and one that absorbs history into a story of shared injury.

Nakamura’s Application and Appointment

In 1959, more out of curiosity than confidence, Nakamura applies for a position with the Japan Blood Bank and is surprised to receive an interview. He travels by train to Osaka early one winter morning. At the company’s headquarters he waits until nearly lunchtime, then is ushered not into the meeting room he expected but into a large executive’s office. He is seated and left alone again, a delay that gives the appointment an air of uncertainty before its real purpose becomes clear.

A man enters behind Nakamura and tells him not to turn around. The man traces the crescent on the back of Nakamura’s neck, checking whether he is the person he suspects. He then recites a passage associated with wartime deaths. Nakamura’s interviewer is Shiro Kota, a former comrade from Manchukuo who has recognized him through this bodily mark and a shared past. Kota explains that old Manchukuo comrades believe Nakamura may do useful work at the company. The interview itself is thereafter perfunctory, as though his appointment has already been settled; Kota congratulates him on the position as he leaves.

Nakamura returns home and nearly sobs as he tells Ikuko what has happened. His astonishment at Kota’s kindness is significant because the job arrives through recognition and a network of former comrades, not through a detailed account of his qualifications. The company becomes the setting for a postwar act of inclusion: men connected by an earlier history make a place for Nakamura in civilian life. That welcome does not erase the history surrounding them, but it gives him a practical form of acceptance that he had not expected.

Narrative Significance

The Japan Blood Bank gathers several of the novel’s questions into one postwar institution. It is a blood-trading business with a charitable public image; its founder is associated in Sato’s account with wartime research on prisoners; and it offers Nakamura employment through Kota’s recognition and the support of old comrades. These details do not make the company itself equivalent to the wartime operation Sato describes. Rather, they set public respectability, disputed responsibility, and personal loyalty beside one another without resolving their tension.

The episode also places private memory against public presentation. A newspaper can make Naito’s charity visible while leaving his alleged wartime role outside the frame; Sato supplies the suppressed account, while Nakamura’s appeal to Japanese victimhood shows how the past may be remembered in ways that soften responsibility. Kota’s intervention gives the same history another consequence: a shared past can be used not only to protect reputations but also to extend kindness and secure a new beginning for a former comrade. The company’s role remains limited but pointed. Through its founder’s reputation and Nakamura’s appointment, the novel shows postwar life taking shape amid both historical evasion and genuine human gestures.
