Satou Tatsuhiro (佐藤 達広) is the main protagonist of Welcome to the N.H.K.. He is a 22-year-old college dropout and self-identified hikikomori who has spent four years in isolation.[1] His life begins to shift after meeting a mysterious girl who offers to help him escape his reclusive state. He was born in Hokkaido and briefly attended Heisei Bunka University before dropping out.[3]
Appearance[]
Satou is a somewhat tall, disheveled man with stubble, messy hair, and pronounced eye bags. He often wears a jacket, cap, and glasses when outside, giving him a stereotypical otaku or stalker look. In moments of desperation, he appears thin and malnourished. He is frequently seen smoking Marlboro cigarettes.
Background[]
Born in Hokkaido, Satou moved to Tokyo after high school. He was a member of the literature club with Hitomi Kashiwa, where they discussed conspiracies and played cards. Though their relationship was ambiguous, mutual feelings were implied. After graduating high school, he left his hometown to attend a university in the Kanto region but dropped out.[1] He did not return to his family home and instead continued living in his student apartment with financial support from his parents.[1] Later, he reunited with his former literature club junior, Kaoru Yamazaki, and joined him in creating an eroge game.[1]
Personality[]
Satou is indecisive, lazy, and deeply paranoid. He believes in conspiracies and often assumes others mock him. His selfishness and avoidance behavior cause him to lie and withdraw, especially when overwhelmed. These traits hurt those around him, including Misaki and Yamazaki. His psychological trauma leads to hallucinations and delusions. Early in the series, he struggles with communication and fears social interaction. Over time, he gains confidence, but his fear of reality persists. He often escapes into fiction—galges, RPGs, and online relationships—to cope with loneliness and inferiority.[1]
He calls himself the "Master of Hikikomori" and has lived in isolation for four years.[1] Although socially withdrawn, he is capable of small outings such as visiting a convenience store. He is prone to lying, which quickly escalates until exposed. He has also experienced hallucinations from drug use and once attempted suicide, leading to a brief hospitalization where his lifestyle was criticized by doctors.[1]
In high school, Satou was cold and dismissive, believing apathy was "cool." He showed little interest in academics, romance, or friendships.

- "ХУŃ" sweatshirt
- In episode 20, Satou wears a sweatshirt with "ХУŃ", likely referencing Russian pop duo t.A.T.u.'s protest slogan "ХУЙ ВОЙНЕ!" ("Fuck the war!"). The stylized "ХУŃ" may be a censored variation of "ХУЙ", preserving phonetics while avoiding explicit vulgarity.
- t.A.T.u. wore similar shirts during televised protests in 2003, defying censorship on shows like The Tonight Show with Jay Leno.[4][5]
- Their album 200 km/h in the Wrong Lane topped Japanese charts, influencing pop culture.[6]
- The slogan
- "ХУЙ ВОЙНЕ!" uses vulgar slang ("хуй" meaning "dick") in place of "нет" ("no") in the anti-war phrase "Нет войне!" ("No to war!"). The "Ń" in "ХУŃ" may substitute for "Й", softening the original profanity.[7]
