by A Wave of Surprise and Celebration After More Than a Decade
In recent years, anime fans particularly those in their 30s, 40s, and older have found themselves repeatedly asking the same question: “Is it really the Reiwa era?” The reason is a growing trend that few could have predicted—the anime adaptation of long-dormant, nostalgic manga series, some of which ended more than 15 or even 20 years ago.
What was once considered unlikely has now become a genuine movement within the anime industry. Thanks to changes in production models, streaming platforms, and renewed interest from adult audiences, works that were once left behind are finally being brought to the screen. The result has been a mix of surprise, joy, and renewed hope among longtime fans.
Tetsunabe no Jan! Gets an Anime 16 Years Later
On December 16, 2025, it was officially announced that Shinji Saijo’s cult-favorite manga Tetsunabe no Jan! would receive its first-ever anime adaptation. The series originally ran in Weekly Shonen Champion (Akita Shoten) from 1995 to 2000, making the announcement a full 16 years after its conclusion.
Known for its intense culinary battles, eccentric characters, and borderline outrageous cooking methods, Tetsunabe no Jan! has long held a special place among gourmet manga fans. Despite its popularity, many assumed it would never be animated due to its age and niche appeal. The announcement therefore came as a genuine shock, instantly igniting discussion across social media.
For many fans, this adaptation represents more than nostalgia—it is proof that no series is ever truly forgotten.
PSYREN Finally Gets Its Long-Awaited Anime
Just one day earlier, on December 15, 2025, another long-standing wish was fulfilled with the announcement of the anime adaptation of PSYREN, originally created by Toshiaki Iwashiro. The manga ran in Weekly Shonen Jump from 2008 to 2010, gaining a dedicated fanbase for its dark tone and distinctive worldbuilding.
The story follows Ageha Yashina, a high school student who acquires a mysterious red telephone card rumored to be connected to a secret organization. After answering the call, he is transported to a ruined future world where survival depends on mastering psychic abilities known as PSI. Ageha is voiced in the anime by Rikuya Yasuda.
Although PSYREN was well-liked during serialization, it never received an anime adaptation at the time—an omission that fans debated for years. Despite ending over a decade ago, the series continued to rank highly in fan-voted “Manga We Want to See Animated” lists at events such as AnimeJapan.
On December 11, 2025, a mysterious countdown began on the official website, culminating in the long-awaited anime reveal. Social media quickly filled with emotional reactions such as:
- “I never thought I’d see this in my lifetime.”
- “I’ve been waiting since the serialization ended.”
For many fans, the announcement felt like a long-delayed reward for years of loyalty.
Katekyo Hitman Reborn! and the Hope for a Complete Adaptation
Another classic title drawing renewed attention is Katekyo Hitman Reborn! by Akira Amano. The story follows Tsuna Sawada, an unremarkable boy whose life changes when the infant hitman Reborn appears and declares Tsuna the next boss of the mafia organization Vongola Family.
The series previously received a 203-episode TV anime that aired from 2006 to 2010, but notably, the final arcs of the manga were never animated. As part of the franchise’s 20th anniversary, short commemorative videos featuring iconic anime scenes are scheduled to be released on YouTube and social media starting January 4, 2026.
The anniversary promotional video has already sparked emotional reactions:
- “The memories came flooding back instantly.”
- “All I can say is thank you.”
These responses have reignited speculation and hope that the unadapted portions of the manga may finally receive an anime continuation.
Calls Grow Louder for a Revival of GS Mikami: Mission Gokuraku Daisakusen!!
While no official announcements have been made, demand remains strong for a revival or sequel to GS Mikami: Mission Gokuraku Daisakusen!!, created by Takashi Shiina.
The series follows Reiko Mikami, a glamorous and ruthless “ghost sweeper” who exorcises evil spirits—often while underpaying and overworking her assistant, Tadao Yokoshima. The TV anime aired from 1993 to 1994, adapting only up to volume 9 of the manga, which ultimately spanned 39 volumes.
Fans have long hoped to see later arcs animated, particularly the climactic confrontation with the demon Astaroth, which showcases Yokoshima’s growth and features the immensely popular character Luciola.
However, obstacles remain:
- Some comedic erotic elements may conflict with modern broadcasting standards
- Several original voice actors, including lead actress Hiromi Tsuru, have passed away
Even so, social media continues to buzz with comments expressing a desire to see Luciola animated and voiced once more—especially amid the current remake boom.
Why Are These Nostalgic Adaptations Happening Now?
Industry observers point to several factors:
- Streaming platforms targeting adult viewers
- Increased value placed on proven IP
- Fans with purchasing power revisiting childhood favorites
- Advances in production that reduce financial risk
Together, these changes have created an environment where reviving older manga is no longer risky—but strategic.
Final Thoughts: A New Era for Old Favorites
The recent surge in anime adaptations of long-finished manga has transformed disbelief into excitement. What once felt impossible is now happening one title at a time, proving that time alone does not diminish a story’s value.
For longtime fans, these announcements feel like reunions with old friends. For newcomers, they offer a chance to discover beloved works with the benefit of modern animation.
If this truly is the Reiwa era, then it may also be the era where unfinished dreams finally return to the screen.
