Yet, beyond the limelight of these popular anime shows and movies, there exists a wealth of undiscovered treasures. Some of these lesser-known gems never received global recognition at all. While they didn’t trend widely, they often offer captivating narratives, intricate characters, and distinctive visuals. Many of these underappreciated anime series went unnoticed due to competition from mainstream shows, lackluster promotion, limited international distribution, or avant-garde storytelling and artistic styles.

If you’re an anime fan seeking fresh suggestions or a novice eagerly wanting to explore more of the captivating world of anime, this handpicked list of ten lesser-known gems is worth your time. Although they might not be as popular as current hits, every title showcases the unique charm that anime offers in its own way.

1. Tree in the Sun (2000)

TV Series (25 Episodes)

Known as the “Father of Manga,” Osamu Tezuka’s influence continues to thrive today. Many are familiar with him as the inventor of characters like Astro Boy and Black Jack, but this prolific mangaka produced over 700 manga titles and sketched more than 150,000 pages throughout his life. Unfortunately, much of his work remains undiscovered, particularly by Western audiences. One of his lesser-known masterpieces is “Tree in the Sun,” a historical drama adapted from his 1981 manga, which won the Shogakukan Manga Award in the general manga category in 1984.

In the year 2000, the anime earned the Excellence Award at the 4th Japan Media Arts Festival. The narrative unfolds in the mid-1800s, a time of significant political and cultural change in Japan, focusing on the unique bond between two main characters who are polar opposites. One is Manjiro Ibuya, a traditional samurai with a strong sense of justice, while the other is Ryoan Tezuka, a progressive doctor studying medicine in the West. Manjiro is not only a talented swordsman but also holds a low rank. His character stands in stark contrast to Ryoan’s carefree demeanor, his affinity for women, and his ambitious goal of becoming a doctor. The story is grounded in reality, with Ryoan’s character inspired by Tezuka’s great-grandfather.

2. Harmonie (2014)

Short Film (25 Minutes)

In the movie “Harmonie,” directed by Yasuhiro Yoshiura as part of the Anime Mirai 2014 project, we follow the story of Akio Honjou, a high school student who finds solace in his tight-knit group of otaku friends. He possesses an extraordinary ability with music, able to remember any tune he’s heard just once. His life takes an interesting turn when he discovers that the melody of Juri Makina, a popular yet aloof classmate, matches the one from his dreams. As they delve into this enigmatic song together, Akio gains access to Juri’s tumultuous inner world and unearths the emotional depths hidden beneath her composed exterior.

The story’s premise revolves around the idea that everyone has their unique universe, delving into the struggle of navigating another person’s. Even the conclusion of “Harmonie” is purposefully ambiguous, inviting various interpretations. The line between dreams and reality remains unclear and unexplored. Ultimately, it’s left for the reader to determine if the events were paranormal, symbolic, or something else entirely. Instead, the tale focuses more on the emotional experiences and connections beneath the surface of characters rather than the plot itself.

3. On-Gaku: Our Sound (2019)

Film (71 Minutes)

The 2019 independent film titled “Ongaku to Manga” was created by Kenji Iwaisawa, who wrote, directed, and animated it. It was inspired by Hiroyuki Oohashi’s 2005 self-published manga of the same name. Made over a span of seven years, the film garnered much praise from critics and won multiple awards, including the grand prize in the Entertainment Division at the 24th Japan Media Arts Festival Award in 2021.

In this movie, we follow the story of three troublemaking teenagers – Kenji, Ota, and Asakura – at school. Bored with their usual squabbles, they decide to establish a rock band out of the blue, despite lacking any musical skills or equipment. They end up using stolen instruments and surprisingly find an authentic sound that resonates with those around them. This film is a tribute to unrefined art, teenage ennui, and the search for purpose through music, offering a deep and laugh-out-loud funny experience.

4. Hyouge Mono (2011-2012)

TV Series (39 Episodes)

Drawing inspiration from Yoshihiro Yamada’s acclaimed manga, “Hyouge Mono” unfolds as a historical drama that takes place during Japan’s turbulent Sengoku Era. The narrative revolves around Sasuke Furuta, a vassal who served under Oda Nobunaga and later Toyotomi Hideyoshi. Unlike the conventional interest in battle or expansion, Sasuke is captivated by the artistic realm, specifically tea ceremonies (chanoyu), pottery, fashion, and architecture.

In the midst of unrelenting conflict, I find myself entangled in the delicate dance between aspirations for power and an unwavering love for the transient elegance of beauty. Navigating through the complex web of courtly scheming, samurai politics, and the enigmatic art of wabi-sabi becomes my daily challenge, all under the watchful eye of a reclusive sensei in the realm of tea. This extraordinary anime adventure offers a profound, artistic exploration into ambition, aesthetics, and the rich tapestry of Japan’s history – a journey that leaves an indelible mark on my soul.

5. Fantastic Children (2004-2005)

TV Series (26 Episodes)

In this science fiction enigma, we trace a band of peculiar, aged-beyond-time children with snowy locks, repeatedly surfacing throughout Europe spanning several centuries. While their physical forms suggest 11-year-olds, their actions exhibit a level of maturity beyond expectation. Age doesn’t seem to affect them, and they display what appears to be supernatural prowess. They are on a quest for a girl, but the only hint they possess is an image labeled as the crescent moon.

The primary plot unfolds in the year 2012, following the journey of two orphans, Helga, who is deeply connected to moon symbols, and her companion Chitto, as they flee from a cruel orphanage.

6. Miss Hokusai (2015)

Movie (90 Minutes)

Based on the manga by Hinako Sugiura, this critically acclaimed film is a historical drama set in 1814 Tokyo. It’s inspired by true events, focusing on Katsushika O-Ei, the daughter of celebrated Japanese artist Katsushika Hokusai. Although Hokusai’s name became widely recognized in Europe during the late 19th century due to the growing interest in Tetsuzo art style, his daughter and her role in his work remain largely unknown. This film seeks to shine a light on O-Ei’s life and her significant contributions to her father’s artistic legacy.

In a delightful twist of history, I found myself immersed in the captivating world of a film that breathes life into the lesser-known tale of O-Ei, the exceptionally gifted third daughter of the renowned artist Katsushika Hokusai. Rather than following a conventional narrative from start to finish, this film offers a collection of intriguing vignettes, providing an intimate glimpse into O-Ei’s life and artistic odyssey.

As I journeyed through her story, I witnessed her quiet yet pivotal role in her father’s work, often going unacknowledged. At the same time, she tenderly cared for her sightless half-sister, all while managing the intricate tapestry of relationships with clients, apprentices, and her own emotional landscape. It was a captivating exploration that left me enchanted and eager to learn more about this remarkable woman.

In her busy life juggling work and personal matters, she stumbles upon Uribo, a benign ghost of a young boy, along with other amiable supernatural entities. Contrary to popular belief, these spirits are not frightening, rather they offer guidance and assistance whenever needed. Okko also interacts with other inn guests, some who grapple with loss and trauma similar to her own. The movie chronicles her growth as she learns compassion and maturity, navigating through her grief.
