Recommendation from Mr. Iwamoto has released a new trailer and key visual ahead of its television premiere. The latest promotional material gathers the anime’s main characters while offering another look at its unusual combination of historical drama, supernatural mysteries and military action.
The anime is scheduled to begin airing in Japan on July 4, 2026. Based on the manga by Hiroshi Shiibashi, the creator of Nura: Rise of the Yokai Clan, the story follows a military academy student who travels across early 20th-century Japan investigating paranormal incidents and searching for people with extraordinary abilities.
New Trailer Previews Supernatural Military Action
The latest trailer provides one of the most complete previews of Recommendation from Mr. Iwamoto so far. It introduces the tense atmosphere surrounding the Army-affiliated Seihou Middle School and shows Kodo Iwamoto confronting supernatural phenomena during missions across the country.
Rather than focusing on ordinary military operations, the school investigates mysterious events and studies powers that could potentially be useful to the Army. Iwamoto is sent to different regions to examine unusual cases, determine whether the reported phenomena are real and identify gifted individuals who may be suitable for recruitment.
The trailer includes supernatural confrontations, sword action and several of the unusual people Iwamoto encounters during his assignments. It also reinforces the anime’s historical setting, combining military uniforms and early 20th-century locations with monsters, curses and abilities that cannot be explained through conventional science.
New Key Visual Brings the Main Characters Together
A new key visual was released alongside the trailer, bringing together the central characters involved in Iwamoto’s missions. The illustration presents the group in military-style clothing while surrounding them with imagery that reflects the series’ darker supernatural atmosphere.
The visual emphasizes that Iwamoto will not remain alone throughout the story. Although he begins as an investigator carrying out orders from the school and the Army, the people he meets gradually become part of a wider group of individuals connected by unusual powers and difficult pasts.
Their different abilities and personalities will shape the series as Iwamoto continues offering selected individuals letters of recommendation to Seihou Middle School. However, the true reason behind his recommendations appears to be more complicated than simply helping the military recruit useful students.
Recommendation from Mr. Iwamoto Premieres on July 4
Recommendation from Mr. Iwamoto will premiere in Japan on July 4, 2026. The series will air on networks including Tokyo MX and Sun TV as part of the Summer 2026 anime season.
- Premiere date: July 4, 2026
- Japanese title: Iwamoto-senpai no Suisen
- Original creator: Hiroshi Shiibashi
- Animation studio: Studio DEEN
- Director: Toshifumi Kawase
- Genre: Historical supernatural action and mystery
The anime stands out among the season’s fantasy titles because it is set in Japan during the 1910s rather than a fictional medieval world or modern school environment. Its historical background gives the supernatural elements a different atmosphere, especially as the story connects mysterious powers to military ambition and national modernization.
Opening Theme “BUDDING” Featured in the Trailer
The new trailer previews the anime’s opening theme, “BUDDING”, performed by THE JET BOY BANGERZ. The energetic song accompanies scenes of investigation, supernatural conflict and the growing group of ability users surrounding Iwamoto.
The ending theme will be “Koko ni Iru”, performed by WOLF HOWL HARMONY. Together, the two songs give the anime a contemporary musical identity while the story and visual design remain rooted in early 20th-century Japan.

- Ending theme: “Koko ni Iru” by WOLF HOWL HARMONY
The title “BUDDING” also fits the story’s focus on young people whose supernatural talents are only beginning to emerge. Iwamoto’s recommendations may give them an opportunity to understand their abilities, but joining a military institution could also expose them to new forms of control and danger.
What Is Recommendation from Mr. Iwamoto About?
The story takes place in Japan during the 1910s, a period of rapid social, political and technological change. Hidden within that changing nation is Seihou Middle School, a special institution operating under the direct authority of the Army.
The school collects information about supernatural events and researches unusual powers that might have military value. Students are not educated only through ordinary lessons. They are also trained and sent on missions connected to phenomena that most members of the public do not know exist.
Kodo Iwamoto is a third-year student at the academy. Under military orders, he travels throughout Japan to investigate rumors involving curses, strange creatures and people capable of extraordinary acts.
Wherever he goes, Iwamoto encounters individuals who believe their powers are illnesses, punishments or dangerous abnormalities. Instead of rejecting them, he often teaches them how to understand or control their abilities before offering them a letter of recommendation to his school.
However, the story raises an important question: why is Iwamoto so determined to bring these people to Seihou Middle School? His actions may appear to support the institution, but his real intentions remain one of the central mysteries of the series.
Kodo Iwamoto Leads the Story
Kodo Iwamoto is voiced by Taito Ban. The character presents himself as a calm, disciplined and capable military academy student, but his behavior suggests that he does not blindly follow every order he receives.
Iwamoto is skilled in combat and investigation, allowing him to confront both supernatural threats and human enemies. His greatest strength, however, may be his ability to understand people who have been isolated because of their powers.
Rather than treating ability users only as military resources, Iwamoto speaks to them directly and attempts to understand how their powers have affected their lives. His letters of recommendation can offer them a place where they are no longer alone, although the school itself may not be as benevolent as he makes it appear.
This contradiction gives Iwamoto an intriguing role. He works inside a military system that wants to use supernatural powers, but he may also be quietly protecting the people that system hopes to control.
Main Voice Cast
The anime features a cast of characters connected to Seihou Middle School and the supernatural cases investigated by Iwamoto. Each new ability user expands the mystery surrounding the academy and its true objectives.
- Taito Ban as Kodo Iwamoto
- Yuki Sakakihara as Kai Haramachi
- Kento Ito as Soichiro Amaha
- Akira Ishida as Bokyo Kizujo
- Masaya Fukunishi as Oni Okuaki
- Takuma Nagatsuka as Shizuma Aonuma
- Gen Sato as Ryu Sazame
- Shinnosuke Tokudome as Mizuhi Awadama
Kai Haramachi and Soichiro Amaha are among the most important characters surrounding Iwamoto. Their relationships with him help reveal different sides of the protagonist and show how the people he recruits become connected to one another through the academy.
The broader cast also gives the anime room to explore several supernatural abilities rather than building the entire story around a single type of power. Every investigation can introduce a different mystery, regional legend or individual struggling with an ability they do not fully understand.
A Military School for Supernatural Abilities
Seihou Middle School is one of the most distinctive elements of the series. It operates as both an educational institution and a secret military research center, collecting gifted students from across Japan.
The academy’s official purpose is to understand supernatural phenomena and find ways to use extraordinary abilities for national defense. However, placing young ability users under military control creates serious ethical questions.
Students may receive training, safety and companionship, but they may also be treated as weapons rather than people. This tension appears to influence Iwamoto’s actions and may explain why his personal goals are not always identical to those of his superiors.
The school therefore serves as more than a background setting. It represents the larger conflict between helping ability users understand themselves and exploiting their powers for political or military purposes.
Historical Japan Meets Supernatural Folklore
Recommendation from Mr. Iwamoto uses its historical period to explore a Japan moving toward modern institutions while still surrounded by folklore, local traditions and beliefs in the supernatural.
The Army attempts to study strange phenomena through organized investigation and research, but many of the cases Iwamoto encounters are deeply connected to villages, religious customs and regional legends.
That contrast gives the series a distinctive visual and narrative identity. Military uniforms, trains and modern weapons exist alongside curses, spirits and people whose bodies can perform impossible acts.
The story can therefore function as both a supernatural action series and a historical mystery. Each mission offers an opportunity to explore a different part of the country while revealing how fear and superstition shape the lives of ability users.
Production Staff at Studio DEEN
Toshifumi Kawase is directing the anime at Studio DEEN. Keiichiro Ochi is responsible for series composition, while Atsuko Nakajima is designing the characters for animation.
The soundtrack is composed by Yoshiki Dewa and Toru Ishitsuka. The music will be important for creating a balance between historical drama, military tension and supernatural horror.
- Director: Toshifumi Kawase
- Series composition: Keiichiro Ochi
- Character design: Atsuko Nakajima
- Music: Yoshiki Dewa and Toru Ishitsuka
- Animation production: Studio DEEN
Studio DEEN will need to recreate several different environments as Iwamoto travels across the country. The story moves beyond the school and includes rural villages, snowy regions, traditional communities and locations affected by supernatural disasters.
The new trailer suggests that the adaptation will emphasize atmospheric backgrounds and dramatic lighting while preserving the distinctive character artwork associated with Hiroshi Shiibashi’s manga.
Based on the Manga by Hiroshi Shiibashi
Recommendation from Mr. Iwamoto is written and illustrated by Hiroshi Shiibashi, best known as the creator of Nura: Rise of the Yokai Clan.
The story was initially published as a one-shot before beginning regular serialization in Shueisha’s Ultra Jump magazine in 2021. The manga has since expanded its historical world, introduced additional ability users and developed the mystery surrounding Iwamoto’s recommendations.
Shiibashi’s previous experience with yokai, folklore and supernatural action makes him particularly well suited to this kind of story. However, Recommendation from Mr. Iwamoto approaches those themes through a more historical and militarized setting than his earlier work.
The manga’s detailed uniforms, traditional locations and supernatural character designs have also given it a strong visual identity that the anime will attempt to preserve.
Why the Anime Could Stand Out
The Summer 2026 season includes many fantasy and supernatural anime, but Recommendation from Mr. Iwamoto has an unusual combination of elements. Its early 20th-century setting, military academy premise and focus on recruiting ability users separate it from more familiar modern exorcist or school battle stories.
The anime also appears interested in the personal consequences of possessing supernatural abilities. The people Iwamoto meets are not always trained fighters. Many of them are frightened, isolated or convinced that something is wrong with them.
By teaching them to understand their abilities, Iwamoto becomes more than an investigator. He becomes a guide who offers them a possible future, even though the destination he recommends may carry dangers of its own.
That moral uncertainty could become one of the series’ greatest strengths. Viewers will need to decide whether Iwamoto is recruiting people for the Army, saving them from persecution or secretly building something that neither the military nor the academy fully understands.
Final Thoughts
Recommendation from Mr. Iwamoto is preparing for its July 4, 2026 premiere with a new trailer and key visual that bring its supernatural military world into sharper focus. The trailer previews the opening theme “BUDDING” while showing Kodo Iwamoto and the gifted individuals connected to his investigations.
With Studio DEEN handling animation, Toshifumi Kawase directing and Hiroshi Shiibashi’s manga providing the foundation, the anime has the potential to become one of the season’s most distinctive historical fantasy series.
For viewers interested in supernatural mysteries, early 20th-century Japan and stories about powerful young people caught between protection and exploitation, Recommendation from Mr. Iwamoto is one of the Summer 2026 anime worth watching.
