Toshiki Inugai (犬飼寿樹 Inugai Toshiki) is the minister of construction's grandson. In 1978 he was kidnapped and taken to an abandoned house in a remote village near Hinamizawa. In an attempt to get help, Toshiki takes advantage of a scar from a prior surgery and fakes pain, encouraging his captors to get medical help from an unaware Kyousuke Irie.

Toshiki's dropped wallet is found by a bystander and turned in to the police. Because it was found in an abandoned area, Akasaka and Ooishi get the clues they need to rescue the boy.


Yoshiroh (義郎 Yoshirou) is one of Shion Sonozaki's uncles. He is one of the initial people to support Shion after her escape from St. Lucia Academy, and offered her a job as an office helper.

Tamae Houjou

Tamae Houjou (北条 玉枝 Hōjō Tamae) was Teppei Houjou's wife and the aunt of Satoko and Satoshi Houjou. Tamae and Teppei fought a lot, and they were very abusive towards Satoko and Satoshi when they became their legal guardians. The abuse intensified when Teppei left the house to live with his mistress. In 1982, Tamae is murdered with a baseball bat on the night of the Watanagashi Festival, becoming the fourth-year victim of Oyashiro-sama's curse. Matsuribayashi reveals that Satoshi was her murderer.

Reiko Ryuugu

Reiko Ryuugu (竜宮 礼子 Ryūgū Reiko) is Rena Ryuugu's mother. She cheated on Rena's father Yasunori with her colleague Akihito, later divorcing him for her lover.

Reiko's first name was long overdue and was finally revealed in Higurashi no Naku Koro ni Sotsu, before which she had simply been referred to as "Rena's mother". It is suggested that Reiko's new surname is Suzuki post-divorce, although it is unclear if this was her maiden name or her new name after marrying Akihito.[2]

Reiko was described by Rena as a highly ambitious and talented career-oriented woman. Full of energy and passion for her job, Reiko was lauded for her leadership and determination; earning her many promotions and tremendous financial success. She began her career as a fashion designer by working for a small clothing factory in Okinomiya—where she met fellow designer Yasunori and soon married him. The couple later moved to Rena's grandmother's house in Hinamizawa when Reiko became pregnant with her. When Rena was in elementary school, the company employing Reiko began to collapse financially. Around that time, Reiko and some of her peers happened to receive a job offer at big design firm in Ibaraki; but Yasunori was not among them. Not wanting to waste away in a rural town, she convinced her husband to move to Ibaraki, even if it meant he would be unemployed.

Reiko was a big hit in Ibaraki and entrusted with one big project after another. She barely had any days off and often came home late at night—sometimes even staying overnight to work on important projects. She didn't get to see her family much, leaving Rena and Yasunori in charge of domestic affairs such as cooking and household chores. Perhaps partially out of guilt, Reiko sometimes took Rena out—treating her daughter to fancy restsurants, amusement parks and the like; unbeknownst to her husband. Sometimes Reiko invited her colleagues as well. At such a summer barbecue, Rena was introduced to a certain Mr. Akihito who seemed particularly close to Reiko. Reiko started inviting Akihito more often on outings with Rena, willing her daughter to get accustomed to him.

One day, Reiko took Rena on a rather lavish outing, pampering her at high-end boutiques and accessory stores without any regard for the price tags. As they took a break at a ridiculously expensive restaurant, she offered to make her daughter's dream come true—which was eating a mountain of parfaits. After treating Rena to fruit parfaits until they couldn't eat any more, Reiko tried to tactfully inform Rena that she planned on leaving her husband to marry Akihito and invited Rena to come live with them. When Rena had an outburst where she vehemently refused, Reiko informs Rena that she can't live with Yasunori anymore because she was pregnant with Akihito's baby. It is unclear whether this was true or just a rouse in a desperate attempt to convince Rena to come with her.

Immediately afterwards, Reiko had left their house, refusing to see Yasunori, and sent a lawyer who told him to not contact Reiko in any form or manner. She had the lawyer carry out the divorce proceedings on her behalf, despite Yasunori's desperate attempts to contact her. Reiko privately met Rena one last time to convince her to join her new family, dismissing the letter that Yasunori had asked Rena to deliver to her. She tells Rena that Yasunori could not offer her a good livelihood, which was the last straw for Rena; prompting her to end all relations to her mother. Reiko is never mentioned afterwards and it is unknown whether she knew of Rena's mental breakdown shortly afterwards and the fact that she had moved back to Hinamizawa with her father. She had however left Rena's father with an enormous amount of money as alimony

In Higurashi no Naku Koro ni Mei, Reiko and Akihito have Nao Houtani together.

Yasunori Ryuugu

Yasunori Ryuugu (竜宮 保典 Ryūgū Yasunori)[3] is Rena Ryuugu's father. His wife Reiko divorced him, and he received a massive amount of settlement money. However, Yasunori was not allowed to contact or meet with Reiko or her new husband.[4] Yasunori and Rena moved back to Hinamizawa in 1982. Many arcs feature Yasunori as a target by Rina Mamiya for badger game scams because of his big bank account.


A man who Rena's mother Reiko fell in love with, causing her to divorce Rena's father Yasunori.

In Higurashi no Naku Koro ni Mei, Akihito and Reiko have Nao Houtani together.


Ootaka (大高 Ōtaka) is Chief Inspector of prefectural police headquarters. He's on bad terms with Kuraudo Ooishi.

In Tsumihoroboshi he takes control of the situation with Rena and the bomb and attempts to raid the school with riot police. Ooishi and Kumagai to try to stall him until they can confirm the hostages are safe and the bomb is disarmed.

In Matsuribayashi Ootaka suddenly shows up at the police station and threatens to ruin Rika's 48-hour plan by asking to inspect Rika's "corpse" himself. Ooishi refuses to let him pass, and Ootaka claims he was asked by Representative Saburou Sonozaki to conduct the investigation. Unfortunately for him, Saburou himself arrives with Akane just then and has no idea who he is. Saburou and Akane drag off Ootaka to "have fun" with kendo practice.

Saburou Sonozaki

Saburou Sonozaki (園崎三郎 Sonozaki Saburō) is one of Mion and Shion's uncles and a member of the prefectural assembly. In Minagoroshi he joins the village protests to save Satoko. In Matsuribayashi he challenges Ootaka's claim of being friends with him and drags him away.


Harayama (原山) is manager of the child consultation center.


Aida (相田) is an employee of the child consultation center.


Saitou (斉藤) is an employee of the child consultation center.


Kamisone (上曽根) is the Japanese Prime Minister, named such in the credits for the Outbreak anime. In Minagoroshi he is convinced to sign permission for usage of the Emergency Manual once Rika's death is reported.


This article or section contains untagged major spoilers for the original Higurashi no Naku Koro ni and possibly the console-exclusive arcs. Readers who have not completed the main story are advised not to proceed further.

Miyoko Tanashi's parents

Takemitsu Tanashi (田無 武光 Tanashi Takemitsu) was Miyoko Tanashi's father and Hifumi Takano's student. He and his wife got into a train accident, with Miyoko's mom dying in it. A wounded Takemitsu tells his daughter to call Dr. Takano and get his help shortly before passing away.


Natsumi's Family (Aki, Touji and Haruko)

Natsumi's family moved from Hinamizawa to another city (Kakiuchi City) despite the complaints of Aki, Natsumi's grandmother and a fierce believer in Oyashiro-sama. Shortly after the Great Hinamizawa Disaster, Aki begins performing bizarre rituals involving the death of animals and placing charms all over the family's house. Haruko and Touji, Natsumi's parents, do their best to keep Aki under control and hide the fact they're from Hinamizawa.

One day Natsumi sees her mother stabbing Aki to death, and a crazed Haruko encourages her family to chop up her body and hide it. The police soon discover Aki's body however, and Haruko assaults Touji for botching the disposal. Touji suggests to Natsumi that they turn themselves in to the police, but Haruko kills him by stabbing him in the throat. Haruko then attempts to kill Natsumi and they wrestle over a knife, leading to Natsumi killing her mother with it.

It's then revealed that Natsumi actually killed Aki. She pushed her down and accidentally killed her when she hit her head on a table, and Natsumi forced her family to chop up her body and hide the parts. She then attacked her dad for messing up the corpse disposal and later killed both of her parents. Haruko managed to call Akira for help when he called the house however.


Akutagawa, Chiaki and Machi

Akira Otobe's companions, who drive to Hinamizawa with him and appear to go missing. It's later revealed that they were part of a suicide group and came to Hinamizawa to kill themselves. Chiaki kept a bank card as a memento of her dead husband, which Otobe stole and ran away with.

Otobe's group discover their bodies inside of their car resting peacefully, and Otobe apologizes to them and tries to return the bank card. Chiaki's ghost appears to let him keep the card and laments that they chose to die instead of live, however Otobe still returns the card and comes out feeling like a much more positive person.


Mifune (三船) is a member of the Sonozaki Family that arranged for Akane Sonozaki's assassination in an attempt to become the next head of the family. He and his henchmen have been isolating Mion's group by getting rid of their vehicles and trying to eliminate them.

Console-Exclusive Arcs

Kazuko Yamase

Kazuko Yamase (山瀬加寿子, Yamase Kazuko) is a nurse who works at Saeki Hospital and the director of the Care and Welfare Center for the Elderly. She first appears in Someutsushi-hen as a kindhearted, passionate caregiver and a mentor to Natsumi Kimiyoshi as she works part-time at the facility. Yamase is described as a gentle woman slightly older than Natsumi's mother who always looks out for Natsumi and appreciates her sincere efforts.

When Detective Tomoe Minai forcefully tries to interrogate Kazuma Hatakeyama (a former resident of Hinamizawa) regarding the Gas disaster, Natsumi intervenes and defends the elderly man. This compassionate act earns Nurse Yamase's admiration and she later urges Natsumi to consider becoming a caregiver after high school. Yamase's compliment greatly touches and encourages Natsumi who was previously distraught regarding her future career prospects.

Yamase is later unexpectedly murdered by a mentally unstable Hatakeyama after he develops the terminal symptoms of the Hinamizawa Syndrome. Natsumi hastily uncovers her dead body as the paramedics are carrying it out, and has a nervous breakdown after seeing her disfigured face.

Chisato Saeki later explains how Yamase was an excellent nurse and that the Care and Welfare Center for the Elderly was actually her proposal to the management. Earlier during her career, Yamase was compelled to leave her bedridden father in her son's care, due to her demanding hours. When her aged father had developed a fever, Yamase's son had treated it like a common cold, when it was actually organ failure and turned out to be fatal. Her regret motivated her to realize that the general population which didn't have medical expertise would feel burdened and incapable of providing adequate care for the ailing elderly. This led to her involvement and passion in establishing the facility at the Saeki Hospital.

Kazuko Yamase's murder along with Kazuma Hatakeyama's suicide becomes one of the main triggers for the events of Someutsushi-hen causing great mental distress to Natsumi who was already facing difficulties on various fronts in this arc.

Kazuma Hatakeyama

Kazuma Hatakeyama (畠山一馬, Hatakeyama Kazuma)is an elderly man hospitalized at the Saeki Hospital's Care and Welfare Center for the Elderly and a former resident of Hinamizawa. He first appears in Someutsushi-hen as an unsociable old man who was admitted to the center recently. Natsumi Kimiyoshi encounters him during her part-time job at the facility and becomes acquainted with him once they both learn about their shared Hinamizawan heritage. Natsumi encourages Hatakeyama to come out of his shell, socialize, and also look forward to recovering and going home to his family.

After the Great Hinamizawa Disaster, Hatakeyama's mental health deteriorates and his nearly delirious worship of Oyashiro-sama becomes a menace to the hospital. He later comes down with a fever after Detective Tomoe Minai attempts to interrogate him forcibly and is scheduled to be transferred to a psychiatric ward. He becomes one of the triggers for the events of Someutsushi-hen as his murder of his caretaker, Kazuko Yamase and eventual suicide become one of the stressors Natsumi faces in this arc.

In Kageboushi-hen, he doesn't play a very significant role in the main story as he did in Someutsushi-hen, having been sent home from the hospital early and it is implied he doesn't meet Natsumi. He however begins to exhibit strange behavior as he does in the previous arc, and begins to fanatically worship Oyashiro-sama after the Great Hinamizawa Disaster. This becomes a big nuisance for his family and a spectacle for the neighbors as observed by Mamoru Akasaka when he visits the Hatakeyama household in this arc. Hatakeyama is later murdered by his neighbor, Kiyoshi Obata—one of his few friends and a former resident of Okinomiya.

Hatakeyama Family

A family who moved to Kakiuchi City from Hinamizawa. Kazuma Hatakeyama, the elder of the family, was admitted to Saeki General Hospital.

Kiyoshi Obata

Kiyoshi Obata (小幡清, Obata Kiyoshi) is a former resident of Okinomiya and one of Kazuma Hatakeyama's only friends in Kakiuchi City. He is first mentioned in Kageboushi-hen. Obata had moved to Kakiuchi City in 1976 and lived across from the Hatakeyama Household. Hence, he hadn't been interrogated by Detective Tomoe Minai and her team as a prospective offender for the mysterious murders happening across Kakiuchi amongst Hinamizawa immigrants, since he had moved to the city two years prior to the Dam Project's termination; while their list of residents only comprised of those who had moved from Shishibone City after 1978.

Obata is the perpetrator of Kazuma Hatakeyama's murder in Kageboushi-hen. At 6.00 PM inside his own house on the 1st of July, 1983, Obata is said to have stabbed Hatakeyama multiple times with a kitchen knife for reasons unknown before committing suicide by stabbing his own throat. This murder was highly unanticipated as Obata did not show any signs of suspicious behavior before the incident. It is speculated that their shared Hinamizawan heritage and Hatakeyama's fanatic behavior after the Great Hinamizawa Disaster may have sparked discord between them leading to their eventual demise.

Mamoru Yamashina

Mamoru Yamashina (山科守, Yamashina Mamoru) is Chisato Saeki's friend and upperclassman. His father is Chisato's chauffeur and his mother runs a café downtown in Kakiuchi City which a lot of students from their school frequent. He makes his first appearance in Kageboushi-hen when Chisato visits his family café with Natsumi Kimiyoshi and Tamako Makimura.

Mamoru is close to Chisato due to their family ties and him being her upperclassman in the same school until he graduated. Tamako; being Chisato's childhood friend; is well acquainted with him too. Mamoru is the one to point out to Natsumi's friends that her hometown Okinomiya is actually adjacent to the village of Hinamizawa, where the gas disaster took place. He knows this as he often visits the main branch of Angel Mort in Okinomiya.

Mamoru is a pragmatic and considerate young man. He is shown to care a great deal for Chisato—teasing her for her rampant behavior even as he gives her valuable advice regarding academics and cheers her up when she is feeling upset about Natsumi. Chisato looks up to him as an "older brother" figure and sometimes lets him in on her weak side. Mamoru often calls Chisato "my lady" albeit sarcastically due to his father being her family's employee, although she resents it and prefers he acts more familiar with her.

It is revealed that Mamoru has feelings for Chisato and has once confessed to her in the past, only to be rejected. Yet, he believes he still has a chance as Chisato continues to be close to him and often visits his shop. Chisato had once told him "Everyone loves people who are self-confident", which inspired him to cultivate such an attitude. It is implied that Chisato may also have some feelings for him but feels hesitant about being in a relationship with him until she becomes more emotionally mature so that they're both on equal grounds.

Kouhei Sawamura

Nagisa Ozaki's boyfriend and one of the students attacked by Rena Ryuugu in the incident at Ibaraki, who was hospitalized after the incident. Despite Kouhei's injuries, he was encouraged by the school not to press charges since they didn't want to have a bad reputation. The Connecting Fragments section reveals that Kouhei and his friends were setting up a haunted house attraction based on real events and obtained Rena's support, however for unknown reasons she attacked them later.

During a regular visit from Nagisa, it is discovered that he jumped from his hospital room on the 8th floor and died upon hitting the ground. It was initially thought to be suicide, but later investigation determined it was murder.

It is later revealed that Youko Hiranuma murdered him. Kouhei's room was originally on the first floor, and he was transferred to the 8th floor at some point. Because the hospital floors have a similar layout, patients often get confused when on other floors and will enter other rooms thinking it's theirs. A fire alarm had been pulled and caused a false alarm, and while Hiranuma was telling other patients not to worry, she told Kouhei there was a real fire. The confused Kouhei made to jump out his room window, thinking he was still on the first floor, and hesitated upon realizing he was on the 8th floor. Hiranuma then used this chance to push him out and kill him.

Youko Hiranuma

A nurse working at a hospital. It is later revealed in the chapter that she was bribed to kill Kouhei by an unknown man and made to run away to some other place by airplane before the police could find out. However, the police corner Hiranuma before she can board the plane and confront her with their information. Unbeknownst to her, the unknown man had slipped something into Hiranuma's drink that caused her to go violently insane. Hiranuma pulls out some knives she stole and tries to fend off the police, but soon kills herself.
