Nagoya Braces for Impact: 'Deramasu' Trend Explodes as The Idolmaster SideM Announces Summer Collaboration

The term "Deramasu" suddenly surged to the top of social media trends in Japan, briefly claiming the number two spot on Yahoo! Realtime Search and sparking intense buzz online. "Deramasu" is a collaborative project that pairs the popular multimedia franchise The Idolmaster with local businesses and tourist attractions throughout Nagoya. The latest announcement regarding its partnership with The Idolmaster SideM (affectionately dubbed "Deramasu M" by fans) has sent producers (the franchise's name for fans) nationwide into a state of sheer excitement.

Storm of Praise for Newly Drawn 'Balletcore' Outfits and Life-Sized Panels

What especially surprised fans was the newly drawn illustration unveiled for the "Deramasu x The Idolmaster Pop-up Store at Manga Exhibition." Fans flooded social media with expressions of gratitude and excitement over the idols' elegant outfits, which are based on the trending "balletcore" fashion aesthetic. "Thank you for dressing my favorite idol in such beautiful clothes," and "The art is just too good," were among the many passionate reactions. Expectations for the collaborative merchandise are sky-high, with some fans expressing shock and awe at premium items like the 200,000 yen (approx. $1,300 USD) life-sized acrylic standees.

Growing Anticipation for Collabs with Local Landmarks and Delicacies

The true charm of "Deramasu" lies in its deep integration with Nagoya’s local culture and culinary scene. Fans are already looking forward to collaborations with legendary local spots such as the shrimp cracker specialist "Ebisenbei no Sato" and the historic tea house "Myokoen." Past visitors who fell in love with Myokoen's teas during previous campaigns have been passionately recommending them online, urging others to try their jasmine and hojicha (roasted green tea). With upcoming announcements from other local favorites like the curry udon chain "Wakashachiya" highly anticipated, Nagoya’s culinary scene is fully prepared to win over the hearts—and stomachs—of visiting fans.

'Nagoya is the Destination This Summer!' Fans Plan Their Pilgrimages

Following this avalanche of announcements, social media has been flooded with posts from fans plotting their trips to Nagoya. Comments such as, "I hear Nagoya summers are brutally hot, but when is the best time to go?" "Nagoya's local businesses are going all out; we definitely need to book an overnight stay," and "My favorite character isn't featured, but the event looks so fun I want to go anyway," highlight the festive atmosphere. Thanks to the shared passion of local businesses, residents, and "producers" from across Japan, Nagoya is set to experience an unprecedented wave of excitement this summer.

The Context

For those unfamiliar, The Idolmaster (officially stylized as THE iDOLM@STER) is one of Japan's most successful and long-running media franchises, revolving around the growth of pop idols. Fans of the franchise are referred to as "Producers" because they take on the role of talent managers. SideM is a popular spin-off branch focusing on male idols, unique for the fact that all the characters had "previous jobs" (such as former doctors, lawyers, or pilots) before changing careers to become idols.

The name "Deramasu" is a clever portmanteau. "Dera" is a well-known dialect word from the Nagoya (Aichi Prefecture) region meaning "super" or "extremely" (similar to Tokyo's "mecha" or "cho"), combined with "Masu" from "Idolmaster." Regional tourism collaborations with anime and gaming franchises have become a highly effective economic driver in Japan, turning casual fans into domestic tourists who contribute significantly to local economies through dining, lodging, and purchasing exclusive regional goods.

Tragedy on Miyajima: 1,200-Year-Old 'Eternal Flame' Hall at Mt. Misen Destroyed by Fire

On the morning of May 20, 2026, a fire broke out near the summit of Mt. Misen on Miyajima Island in Hatsukaichi City, Hiroshima Prefecture—a site recognized as a UNESCO World Heritage island. The blaze completely destroyed the "Reikado Hall" of Daishoin Temple, which enshrines the "Eternal Flame" (Kiezu-no-hi), a sacred fire associated with the Buddhist monk Kobo Daishi (Kukai). Despite a large-scale emergency response involving eight fire engines and helicopters, which succeeded in bringing the fire under control by 10:35 AM that day, the loss of the historic building has left the public in shock. Reikado Hall is a vital cultural structure that serves as the repository for the "Eternal Flame," which is said to have burned continuously for approximately 1,200 years since Kukai first lit it during his ascetic training. This fire is also significant for being one of the source flames for the "Flame of Peace" in Hiroshima Peace Memorial Park, holdin...
