The Fourth One-Night-Only Revival

In the early hours of November 15, 2025, *Asai Ryo to Kato Chie no All Night Nippon 0* (朝井リョウと加藤千恵のオールナイトニッポン0) returned to the airwaves for the fourth time as a one-night-only special. The show originally ran as a weekly Friday programme from April 2015 to March 2016, and after a six-and-a-half-year silence it staged its first comeback in October 2022, followed by September 2023 and August 2024. The two hosts have also openly admitted that their original casting was 100% by personal connection rather than merit.

This edition came with an added twist: a simultaneous live stream on the video app 17LIVE (イチナナ), making it the first broadcast to include visuals in roughly nine and a half years. The show also noted that the three previous revival episodes will now be archived as podcasts — though the final ten minutes of the 2023 broadcast no longer exist at Nippon Broadcasting, and despite a team-wide search, the data was never found.

Birthday Dinner and the Bidet Incident

Two days before the broadcast, a birthday celebration dinner for Kato was held among friends. The group was warned by staff for laughing too loudly, yet stayed for over four and a half hours, closing out the restaurant as the last table.

The evening's standout moment came from the bathroom. Kato pressed the bidet button and the water simply would not stop. No matter which button she tried, nothing worked. The main power plug was out of reach, standing up was not an option, and calling for help meant running into the very staff member who had just reprimanded them. She described herself as 'the boy who held back the flood,' sitting perfectly still for several minutes until — miraculously — it stopped by itself. The rest of the table, hearing distant laughter from the bathroom, had found it annoying without knowing the cause.

At the dessert wagon, everyone was picking modest portions — until Asai, last in line, simply said, 'I'll take everything on the right side.' The room was stunned. His reasoning: Murata and Nishi would end up eating it anyway, so he figured he might as well claim it all upfront.

The Card Theme: Most Memorable Food of 2025

The episode's card theme — 'something you ate in 2025 that left an impression' — was born from a single LINE message. On July 5, writer Nakamura Ko (中村甲) texted Kato out of nowhere to say he was in Gifu and about to have a large unaju with Kumada Yoko (熊田陽子). Kato forwarded it to the writers' group chat, nicknamed 'the emotional trash can,' shared with Asai, Nishi Kanako (西かな子), and Murata Sayaka — and it caused an uproar. The specific combination of the date, the location, and the companion made the message impossible to forget, and it became the direct inspiration for the theme.

Listener cards brought their own memorable entries: one described eating a 'sashimi version of buri daikon,' wrapping Toyama Bay yellowtail in pickled radish with soy sauce at a concept café in Nagoya; another recounted a nephew bringing a Beyblade to a yakiniku restaurant and burning the meat, leading to a redemption visit two weeks later with a spouse that tasted like a completely different dish.

Writer Gatherings — The Mango Disaster and the Tetris Showdown

Two stories emerged from a visit by Nakamura Ko, Murata Sayaka (村田沙耶香), and Asai to Kato's home.

First, Tetris. Kato is skilled at *Tetris 99*, the Nintendo Switch online battle game, and ended up demonstrating her abilities to Nakamura. Deep into a 99-player nationwide match, climbing steadily into the top ten, Nakamura asked how high she had ever ranked. Without taking her eyes off the screen, Kato turned just her profile to him and said flatly: 'Second.' The comic-book delivery brought the room down. She later claimed first place and announced it in the group chat, and through Murata Sayaka it emerged that novelist Kanehara Hitomi (金原ひとみ) is also a former champion — setting up a future showdown.

Then, the mango. Nakamura Ko arrived with a high-quality mango, excused himself to the kitchen, diced it into a grid pattern, flipped the skin to fan out the cubes, and presented it triumphantly at the table. Asai declined, saying it smelled like gasoline. Kato's first-grade son disliked mango. Kato herself was not comfortable eating it as-is. Murata Sayaka couldn't manage it either. With no takers, the mango sat drying out on the table until Nakamura ate the entire thing alone. Murata Sayaka laughed so hard she cried.

The Parfait Outing

When novelist Koike Mizune (小池水音) posted on X (formerly Twitter) that she had been interviewed by the TV programme *Hirunandesu* while holding two buckwheat crepes, Kato — a devoted sweets lover — reached out and proposed getting dessert together. Koike suggested a parfait specialty restaurant, comedian Timondii Maeda (ティモンディ・前田) joined the plan, and the four of them arranged an outing.

When Kato told Koike that Maeda would be coming, Koike replied: 'Oh wow! I'm so happy to meet him. I hope the parfait will be loved.' The phrasing — speaking as a representative of the parfait rather than of herself — caught Kato off guard. 'Koike-san existed as the parfait that day,' Kato later said.

The restaurant didn't take reservations, so the group headed out early to queue for tickets — only to find Koike had arrived even earlier. While waiting for Maeda and Asai, Kato and Koike fell into a conversation about near-zero ordinary savings account interest rates and whether they should be investing: about as far from a parfait as a conversation could get.
