Nao Iwamoto

Nao Iwamoto is a Japanese manga artist from Okayama Prefecture who broke out in the early 2020s with her office romance series The Ice Guy and His Cool Female Colleague. The manga, about a woman and a man descended from a snow spirit, sold over 2.5 million copies worldwide after its 2023 anime adaptation on Crunchyroll. Iwamoto's work is known for its clean line art, soft pastel palettes, and slow-burn emotional storytelling. She is also the creator of Love After World Domination, a superhero-villain romantic comedy, and currently serializes the music-themed romance Kimi no Koe ga Kikitai in Monthly Shonen Gangan. Fans praise her for capturing the quiet awkwardness of falling in love.[edit]

Iwamoto grew up in Okayama Prefecture, drawing characters from anime and manga from a young age. She cites Rumiko Takahashi's works and Studio Ghibli films as major influences. During high school, she decided to pursue art professionally and enrolled at an art university in Okayama, where she studied design and illustration. While in university, she began creating doujinshi and selling them at Comiket starting in 2017. In 2018, she submitted a one-shot manga to a Square Enix competition and won an honorable mention. That one-shot, Koori no Koi wa Itsumo Samui (later retitled The Ice Guy and His Cool Female Colleague), was published in Gangan pixiv in 2019. The positive reader response was immediate, and Square Enix quickly greenlit a full serialization.[edit]

Iwamoto's professional debut came in 2019 with the one-shot that became The Ice Guy and His Cool Female Colleague. The series ran in Gangan pixiv and quickly built a loyal readership. In 2020, she launched a second series, Love After World Domination, in Monthly Shonen Gangan. The following year, she began adapting the light novel Our Last Crusade or the Rise of a New World into manga form for Gangan Joker. By 2022, The Ice Guy had reached 1 million copies in circulation, and an anime adaptation was announced. The anime premiered on Crunchyroll in January 2023, becoming a breakout hit and driving manga sales past 2.5 million copies worldwide. In 2024, she published a one-shot titled Hoshi no Furu Machi and started a new serialization, Kimi no Koe ga Kikitai, a music-themed romance. Love After World Domination completed its run in 2025 with 7 volumes. As of 2026, Iwamoto continues serializing Kimi no Koe ga Kikitai and is preparing an art book, Ice and Fire, collecting illustrations from her first two major series. A stage play adaptation of The Ice Guy and His Cool Female Colleague is scheduled for a Tokyo run in November 2026.[edit]

Iwamoto is known for her clean, expressive line art and soft pastel color palette, often using cool blues and whites for romance scenes. Media outlets portray her as a rising star in the office romance subgenre, comparing her to other josei-focused artists. On social media, she is polite and encouraging, posting sketches and series updates on X (formerly Twitter) where she has about 180,000 followers. She rarely engages in controversy and keeps her personal life completely separate from her public persona. Fans on Reddit hold weekly chapter reaction threads, and on Pixiv, fan art of Fuyutsuki and Himuro is frequently posted on the unofficial Office Romance Day, the 15th of each month.[edit]

Nao Iwamoto commands a steady, dedicated readership rather than the frenzied crowds that greet pop idols. Her influence is measured in serialized runs and global licensing deals rather than viral social media campaigns or organized fan rituals. As of August 2026, iFANN has evaluated her standing within the global cultural landscape, but she currently holds no placement in the published rankings for the Global Top 1,000 or any specific scope list. This absence of a numeric rank reflects her status as a creator whose work resonates through the pages of magazines like Monthly Flowers instead of chart-topping streams or billboard appearances. The audience for her manga consists of individual readers who follow her art on platforms like X (formerly Twitter) without a unified collective noun or formal fan club name. While her works like The Ice Guy and His Cool Female Colleague have sparked widespread discussion on community hubs such as MyAnimeList, these interactions remain standard consumption patterns rather than activist-style support drives. There are no documented subway ads funded by fans or street shutdowns caused by her popularity. Her professional mythology is built on industry milestones, including the announcement of a new anime adaptation for The Seven Knights of the Marronnier Kingdom scheduled for late 2026. This news generated significant online delight among existing readers, marking a peak in her visibility within the anime industry. Unlike performers who rely on live concerts to build their legend, Iwamoto's iconic moments are confined to the publication of award-winning stories and the successful transition of her intellectual property to screen. The lack of a formal fandom name underscores the nature of her career; she is an artist celebrated for her quiet storytelling and clean line art rather than a celebrity defined by a specific group identity.[edit]

Nao Iwamoto's favorite character from her own work is Himuro from The Ice Guy, because she finds his overthinking and awkwardness relatable. She is a self-taught digital artist, learning Clip Studio Paint entirely through online tutorials. The character Fuyutsuki's hairstyle was based on a real office worker Iwamoto saw in a Tokyo café. She collects snow globe figurines, which inspired the snow spirit theme in The Ice Guy. Her favorite food is okayonomiyaki from her hometown, Okayama. A major milestone in her career occurred when she won the 55th Shogakukan Manga Award for her work Tengu's Child, establishing her reputation as a top-tier talent capable of handling complex narratives. Another defining moment arrived in June 2026 with the official announcement that her fantasy manga The Seven Knights of the Marronnier Kingdom would receive a TV anime adaptation. The series was scheduled to premiere on October 3, 2026, on NHK Educational TV, generating significant online delight among fans due to its premise of seven handsome knight brothers. Additionally, her work Gold Kingdom and Water Kingdom gained international recognition when it was screened at the Camera Japan Rotterdam 2023 festival in the Netherlands, highlighting its unique blend of fantasy and diplomatic journey themes.[edit]

Iwamoto is intensely private about her family. In a rare interview, she mentioned that her parents were supportive of her artistic career from the start. She has not publicly disclosed whether she has any siblings. As of 2026, she lives alone in Tokyo, focusing on her work. She has no known pets.[edit]

Iwamoto works closely with editor Miyu Tanaka at Square Enix. The anime adaptation of The Ice Guy and His Cool Female Colleague was directed by Go Kawanaka at Studio Zero-G, with Yui Ishikawa and Chiaki Kobayashi voicing the leads. She has contributed to anthologies published by Kadokawa.[edit]

Nao Iwamoto maintains a strict policy of privacy regarding her personal and romantic life. She has never publicly confirmed any romantic relationship, marriage, or partnership. As of 2026, there are no credible reports, leaks from Japanese tabloids, or official statements regarding a dating history, spouse, or children. Her social media presence is exclusively focused on her work. Her relationship status is single.[edit]

As things stand in 2026, Nao Iwamoto's net worth is estimated at around $1 Million per iFANN's editorial analysis. Her primary income comes from manga serialization fees, volume royalties, and anime licensing. The Ice Guy and His Cool Female Colleague has sold over 2.5 million copies worldwide, with typical manga artist royalties of 8-10% per volume. At a retail price of about ¥700 per volume, her lifetime earnings from that series alone likely exceed ¥140 million before taxes and fees. She also earns from her other series, merchandise, and art sales at conventions. Anime licensing for a first-time author typically pays a flat fee of ¥3-5 million per season. Her net worth has grown steadily since her debut, with the biggest jump coming after the 2023 anime release.[edit]

Iwamoto has not won any major industry awards as of 2026. Her recognition comes primarily from commercial success and fan popularity. She received a Thank You plaque from Crunchyroll in 2023 for the global success of The Ice Guy and His Cool Female Colleague.[edit]
