What kind of person is Heizo Hattori?
Is he an even sharper detective than Heiji?
Heizo Hattori is the father of Heiji Hattori, the celebrated high school detective of western Japan. He does not appear often, but his presence immediately changes the atmosphere of a case.
Heizo serves as chief of the Osaka Prefectural Police and holds the rank of superintendent supervisor. His exact age has not been disclosed. The manga and anime consistently present his deductive ability as surpassing Heiji’s, although they do not establish a formal ranking against every other master detective in the series.
Usually quiet and narrow-eyed, Heizo can open one eye in anger and become genuinely intimidating. At home, however, he is noticeably softer with his wife. This contrast between stern police commander and devoted husband is a major part of his appeal.
This guide covers Heizo’s position, rank, undisclosed age, family relationships, deductive style, and his important manga, anime, and movie appearances. Story details follow, so readers who want to remain completely unspoiled should proceed with care.
Who Is Heizo Hattori? Heiji’s Father and Chief of the Osaka Prefectural Police
Heizo Hattori is Heiji Hattori’s father and the chief of the Osaka Prefectural Police. Like his son, he has formidable deductive ability, but his role differs from that of a teenage detective who personally rushes into each crime scene.
Heizo’s strength lies not only in identifying a culprit, but also in deploying investigators, anticipating people’s choices, and directing a case through the police organization. He approaches an investigation as a commander responsible for the entire board.
- Name: Heizo Hattori
- Position: Chief of the Osaka Prefectural Police
- Rank: Superintendent supervisor
- Age: Not publicly disclosed
- Wife: Shizuka Hattori
- Son: Heiji Hattori
- Childhood friend and close friend: Ginshiro Toyama
- Current Japanese voice actor: Kazuhiro Yamaji
- Previous Japanese voice actor: Takehiro Koyama
Heizo is exceptional on his own terms, not simply because he is Heiji’s father. If Heiji is the passionate detective who charges toward the truth, Heizo is the commander who watches the full board from a measured distance.
Chief of the Osaka Prefectural Police, Rank of Superintendent Supervisor
Heizo’s position is chief of the Osaka Prefectural Police, while his police rank is superintendent supervisor. The position and the rank are related, but they are not the same thing.
- Chief of the Osaka Prefectural Police: the position leading the prefectural police headquarters
- Superintendent supervisor: Heizo’s rank as a police officer
As the head of the organization, Heizo must consider personnel, information control, public safety, evidence, and a suspect’s possible escape route, not just the answer to the mystery. Solving a case is only part of his responsibility; he must also ensure that the police act effectively and bring the matter to a lawful conclusion.
His Age Is Undisclosed: An Estimate in His Fifties Is Not Confirmed
Heizo Hattori’s age has not been officially disclosed. Some readers may estimate that he is in his fifties because he is Heiji’s father, because of his appearance, and because he leads the Osaka Prefectural Police, but none of those clues establishes an exact age.
He appears to belong to the same generation as Shizuka Hattori and Ginshiro Toyama, yet that does not provide a confirmed birth date. His professional role and family connections are clear, while personal details such as his age remain deliberately sparse.
Japanese Voice Actor Changed from Takehiro Koyama to Kazuhiro Yamaji
Heizo was previously voiced in Japanese by Takehiro Koyama and is currently voiced by Kazuhiro Yamaji. Heizo speaks little and often gives short instructions in a low voice, which makes the weight of each line especially important.
His authority does not depend on shouting; even restrained delivery can silence the people around him and sell his position as police chief. When his calm manner gives way to visible anger, the change becomes even more striking.
Usually Quiet, but He Opens One Eye When Angered
Heizo normally wears a narrow-eyed expression. That does not mean he never opens his eyes. When enraged, he may open one eye and show a much sharper expression.
Nothing in Heizo’s established characterization treats this feature as evidence of blindness, a prosthetic eye, or an injury-related history. It should therefore be kept separate from characters such as Kansuke Yamato and Hyoue Kuroda, whose eye injuries are connected to their backgrounds. In Heizo’s case, the expression visually reinforces his emotional restraint.
Heizo Hattori’s Family and His Relationship with Ginshiro Toyama
Heizo has several distinct faces beyond his official role. He is a demanding father to Heiji, a softer husband with Shizuka, and a trusted lifelong friend to Ginshiro Toyama.
His distance and manner change significantly depending on whom he is dealing with, giving his character much more warmth outside an investigation.
A Strict Father Who Pushes Heiji to Improve
Heizo treats Heiji sternly. He reprimands his son for intruding into police work and does not offer easy praise when Heiji’s reasoning is incomplete. This does not mean that Heizo fails to recognize Heiji’s talent.
He understands that Heiji has outstanding deductive ability and a strong sense of justice, but he also knows that a police case can endanger victims, investigators, and civilians. At times, Heizo anticipates Heiji’s temperament and uses that knowledge to move the investigation forward.
Rather than simply handing his son an answer, Heizo makes him reach it through his own reasoning. The method is harsh, yet it also suggests trust. For Heiji, his father is both an intimidating parent and a nearby standard he still wants to surpass.
A Softer Side with His Wife, Shizuka Hattori
Heizo’s wife is Shizuka Hattori, Heiji’s mother. Shizuka is skilled in kendo and highly observant in her own right. She is not merely a passive supporter; she thinks independently and can judge the abilities of Heiji and Conan Edogawa when needed.
At police headquarters, Heizo projects overwhelming authority. At home, he is noticeably indulgent toward Shizuka. That domestic softness shows that the formidable police chief is not simply a cold figure defined by rank.
Ginshiro Toyama Is His Childhood Friend and Closest Ally
Ginshiro Toyama is Heizo’s childhood friend and close friend. Within the Osaka Prefectural Police, Ginshiro serves as chief of the Criminal Investigation Department and holds the rank of senior superintendent. He is also one of Heizo’s most trusted operational partners.
Their long relationship allows them to act with little explanation. Heizo oversees the wider organization, while Ginshiro coordinates investigators closer to the field. Their children, Heiji Hattori and Kazuha Toyama, are childhood friends as well. The children’s closeness grows against the background of a long-standing bond between their fathers.
Why Heizo Hattori’s Deductive Ability Stands Out
Heizo’s deductive ability is presented as surpassing Heiji’s. Heiji and Conan are both excellent at uncovering culprits and tricks, but Heizo’s particular strength is turning deductions into a coordinated police operation.
He reads personalities, predicts movement after a crime, deploys investigators, and shapes the whole field of action. That broader command perspective is what makes his reasoning feel so formidable.
His Reasoning Is Presented as Surpassing Heiji’s
Heiji has solved many difficult cases and often reasons on a level close to Conan’s. Heizo is nevertheless portrayed as reaching beyond his son, which places his intellect at an exceptionally high level.
Heizo does not usually gather everyone for a long detective performance. Once he has the information he needs, he issues orders and closes off a culprit’s options. His reasoning is expressed through the finished investigation rather than through spectacle.
Volumes 31-32: He Even Builds Heiji into His Operation
Volumes 31-32 and The Osaka Double Mystery – The Naniwa Swordsman and Toyotomi’s Castle (2 Hour Special) show Heizo’s reasoning and command at their strongest. The story connects a case from thirteen years earlier to events in the present and places the Osaka police under pressure.
Heizo moves toward the larger truth while anticipating the suspect, the investigators, and Heiji’s likely behavior. His harsh treatment of Heiji is not merely a family argument; part of it pushes his son to pursue the truth in a way Heizo expects.
“Submit quietly and be bound!” (unofficial translation)
The line conveys both certainty about the culprit and the authority of the police chief. Heiji races toward the truth, while Heizo has already incorporated that movement into the larger operation.
Volumes 50-51: Advice Even When He Is Away from the Scene
In Volumes 50-51, Heizo’s intelligence influences Heiji Hattori vs. Shinichi Kudo: Deduction Battle on the Ski Slope! (1 Hour Special). The case follows middle-school-age Heiji and Shinichi Kudo as they approach the same mystery from different locations.
Heizo is not at the center of the crime scene, but he organizes the limited information available and gives Heiji guidance. He does not simply reveal everything. He offers only what is needed while leaving room for his son to reason independently. Even a brief intervention is enough to move Heiji’s thinking forward.
No Confirmed Ranking Against Yusaku Kudo or Conan
Although Heizo is presented as surpassing Heiji, the story does not establish an official ranking between Heizo, Yusaku Kudo, and Conan Edogawa. Heizo and Yusaku have not been shown competing under identical conditions.
Their styles are different enough that a simple strongest-to-weakest list would overstate the evidence.
- Heizo Hattori: directs a police organization and controls the full investigation
- Yusaku Kudo: uses extensive knowledge and observation to reach the truth from limited clues
- Conan Edogawa: finds inconsistencies at the scene and breaks down tricks and criminal psychology
Heizo’s distinctive advantage is the experience and command authority attached to leading the Osaka Prefectural Police, not a confirmed universal ranking.
Heizo Hattori’s First and Important Manga and Anime Appearances
The story beginning in Volume 15, File 10 is Heizo’s first substantial speaking appearance. A briefer earlier depiction may be counted differently, so this is best understood as his full character introduction rather than an uncontested first glimpse.
International mappings and official English display titles are not confirmed for every early entry below. In those cases, the Japanese episode reference is retained, and any romanized title is identified as tentative rather than presented as an official English title.
Volumes 15-16, Japanese Episodes 77-78: English Title and International Mapping Unconfirmed
The case in Volumes 15-16, beginning with File 10 of Volume 15, is Heizo’s first substantial appearance with dialogue, although a brief earlier depiction may be counted as his first sighting. Its anime adaptation is Japanese episodes 77-78, but an international episode mapping and official English display title for those installments remain unconfirmed.
Heizo appears as the head of the Hattori family and immediately carries a heavier atmosphere than his energetic son. Even short exchanges communicate the authority expected of the Osaka police chief. A very brief earlier depiction may be classified as his first visual appearance, so the wording here remains limited to his first substantial introduction.
Volume 19, Episodes 124-125 (Japanese Episode 118): The Naniwa Serial Murder Case (1 Hour Special)
Volume 19 and The Naniwa Serial Murder Case (1 Hour Special), Episodes 124-125 (Japanese episode 118), place the investigation within the Osaka Prefectural Police. The story also features Ginshiro Toyama and helps establish his relationship with Heizo.
The two men are childhood friends and trusted allies, while their official roles create a clear chain of command. The episode shows that their partnership is more than a routine supervisor-subordinate relationship and gives the Hattori and Toyama families a shared history beyond Heiji and Kazuha.
Volumes 31-32, Episodes 282-285 (Japanese Episode 263): The Osaka Double Mystery – The Naniwa Swordsman and Toyotomi’s Castle (2 Hour Special)
The Osaka Double Mystery – The Naniwa Swordsman and Toyotomi’s Castle (2 Hour Special), Episodes 282-285 (Japanese episode 263), is Heizo’s defining showcase. Its manga material spans Volume 31, File 8 through Volume 32, File 4.
Heizo connects the earlier and present-day incidents and uses the Osaka police to close in on the culprit. He also anticipates how Heiji will react. Scenes that first resemble a father-son clash later take on an investigative purpose, bringing Heizo’s roles as father and commander together.
Volumes 50-51, Episodes 536-537 (Japanese Episode 490): Heiji Hattori vs. Shinichi Kudo: Deduction Battle on the Ski Slope! (1 Hour Special)
Episodes 536-537 (Japanese episode 490) depict middle-school-age Heiji and Shinichi approaching the same mystery before they know each other as well as they later will. The official display title is Heiji Hattori vs. Shinichi Kudo: Deduction Battle on the Ski Slope! (1 Hour Special).
Heizo supports Heiji with advice without taking away his chance to think. Yusaku stands behind Shinichi’s side of the story, while Heizo stands behind Heiji’s. The fathers’ intellect makes the east-west contest feel broader than a rivalry between the two young detectives alone.
Volumes 79-80, Episodes 762-767 (Japanese Episodes 710-715): Everyone Saw and Heiji Hattori and the Vampire Mansion
Everyone Saw (Part 1), Episode 762 (Japanese episode 710), and Everyone Saw (Part 2), Episode 763 (Japanese episode 711), lead into the mansion story. Heiji Hattori and the Vampire Mansion then runs from Episodes 764-767 (Japanese episodes 712-715), although exact English display titles are confirmed here only for parts 1 and 4.
The transition toward the mansion begins with a message from Heizo to Inspector Otaki asking whether vampires exist. Because no official English wording has been confirmed, that phrasing should not be treated as an official translation.
“Otaki… do you think vampires exist in this world?” (unofficial translation)
The line does not confirm that Heizo sincerely believes in the supernatural. Its effect is to signal that an unusual case is beginning. Even away from the scene, his voice can sharply change the story’s mood.
Episode 1023 (Japanese Episode 966): Kaiju Gomera vs. Kamen Yaiba (Interlude)
Heizo also appears in Kaiju Gomera vs. Kamen Yaiba (Interlude), Episode 1023 (Japanese episode 966). It is an anime-original story.
Inspector Otaki reports upward to Heizo and Ginshiro as senior figures in the Osaka police. Heizo does not take center stage for a long deduction. Instead, the flow of information to him demonstrates the size and hierarchy of the police response.
Volume 106: A Later Manga Appearance with No Confirmed English Title
Heizo appears in Volume 106, Files 6-10, corresponding to overall Files 1129-1133. No official English title is confirmed for this manga storyline, so no English story title is asserted here.
The story returns to figures connected with the Osaka police and the Hattori family. Its presence means that Volumes 79-80 were not Heizo’s final manga appearance. Readers waiting for an adaptation should be aware that discussion of Volume 106 may reveal later manga developments.
Detective Conan Movies Featuring Heizo Hattori
Heizo also appears in four Detective Conan movies as Heiji’s father and a senior Osaka police official. He is not the central detective in these films, but he may appear when a case expands to involve the larger police organization.
These appearances are movie-only evidence and should not be used by themselves to establish manga or television canon facts.
Movies 10, 14, 17, and 21: Official English Titles
- Movie 10: The Private Eyes’ Requiem
- Movie 14: The Lost Ship in the Sky
- Movie 17: Private Eye in the Distant Sea
- Movie 21: The Crimson Love Letter
These four films have official English titles listed by TMS Entertainment. Heizo’s involvement generally follows Heiji’s connection to a case or the escalation of events toward the Osaka police.
The twenty-first movie places many Osaka- and Kyoto-connected characters in the same story, making the family background easier to feel. Heizo still does not spend the full film reasoning beside Conan and Heiji. Even a short movie appearance can signal that a case has grown large enough to concern the police leadership.
Summary
Heizo Hattori is Heiji’s father, chief of the Osaka Prefectural Police, and a superintendent supervisor whose exact age remains undisclosed. He leaves an impression through authority and precision rather than through frequent appearances.
His severity toward Heiji does not mean that he dismisses his son’s talent. He knows the risks carried by victims, officers, and civilians, so he expects Heiji to reach the truth with discipline. Heizo reads not only the culprit, but also investigators, Ginshiro, and Heiji, then directs the case as a complete operation.
Yet the intimidating chief is softer with Shizuka and shares deep trust with Ginshiro. The combination of controlled commander, demanding father, loyal friend, and affectionate husband is what makes Heizo such a compelling character.
