Neon Genesis Evangelion is the most discussed anime in history. Not the most watched — but the most analyzed, debated, interpreted, and reinterpreted. Hideaki Anno’s 1995 series reached into Christian iconography, Jungian psychology, and Japanese otaku culture and wove them into something that still generates new essays and interpretations thirty years later.
I’m a native Japanese speaker, and Evangelion’s Japanese is extraordinary because it operates on multiple levels simultaneously. Words like 使徒 (apostle/angel), 心 (heart), 自分 (self), and 逃げる (to run away) are simultaneously battle vocabulary, psychological states, and spiritual concepts.
This guide covers 18 essential Evangelion words — the language of depression, transcendence, and the question of what it means to exist.
Why Evangelion Matters for Japanese Learners
Evangelion uses vocabulary that operates at different registers simultaneously. The surface layer is military sci-fi (パイロット, 使徒, エヴァ). The psychological layer uses emotion vocabulary that’s among the most useful in all of Japanese (心, 感情, 恐怖, 深層). The philosophical layer reaches into Japanese Buddhist and Shinto concepts.
This layering means that Eva vocabulary is broadly useful across many contexts — not just for watching anime, but for discussing psychology, philosophy, and human experience in Japanese.
1. 使徒 (shito) — Angel / Apostle
Reading: しと (shi-to) Meaning: In Christianity: apostle (Jesus’s twelve disciples). In Eva: Angel (the enemy beings)
The Christian vocabulary: Anno deliberately chose Christian terminology for its visual impact and emotional weight — while largely making up his own mythology. 使徒 in Japanese Christianity means “apostle” (the twelve disciples of Jesus). Using it for giant alien entities creates a specific kind of awe and dread.
Everyday use: 使徒 appears in religious contexts:
- 使徒言行録 (shito genkoroku) = Acts of the Apostles (Bible)
- 十二使徒 (jūni shito) = the Twelve Apostles
2. 人類補完計画 (Jinrui Hokan Keikaku) — Human Instrumentality Project
Reading: じんるいほかんけいかく Meaning: A plan to merge all human consciousness into one — literally “humanity supplementation project”
Breakdown:
- 人類 (jinrui) = humanity, humankind
- 補完 (hokan) = supplementation, complementing what is incomplete
- 計画 (keikaku) = plan
The vocabulary value: 補完 (hokan) = to supplement, to complete what is lacking — appears in: 補完資料 (hokan shiryō) = supplementary materials, 相互補完 (sōgo hokan) = mutual complementation.
3. 逃げる (nigeru) — To Run Away / To Escape
Reading: にげる (ni-ge-ru) Meaning: To flee, to run away from something
In the show: 「逃げちゃダメだ、逃げちゃダメだ、逃げちゃダメだ…！」(Nige-cha dame da × 3) = “I mustn’t run away.” Shinji’s mantra — repeated as he steels himself to pilot the Eva.
Grammar note: 〜ちゃダメだ (-cha dame da) = “mustn’t [verb]” — a colloquial contraction of 〜てはいけない (te wa ikenai).
Everyday use:
- 逃げる (nigeru) = to run away, to flee
- 逃げ出す (nigedasu) = to escape, to break free
- 現実逃避 (genjitsu tōhi) = escapism (fleeing reality)
- 逃げ場 (nigeba) = a way out, an escape route
4. 心 (kokoro) — Heart / Mind / Inner Self
Reading: こころ (ko-ko-ro) Meaning: The emotional/spiritual heart — one’s inner self
In the show: Eva’s deepest question is whether Shinji can open his 心 to others — whether the AT Field (representing the isolation of self) can be lowered.
Cultural depth: 心 is one of the most profound words in Japanese. It appears in: 心理 (shinri) = psychology, 心臓 (shinzō) = physical heart, 心配 (shinpai) = worry. The classical text Kokoro (心) by Natsume Sōseki is one of Japan’s most important novels.
5. 感情 (kanjō) — Emotion / Feeling
Reading: かんじょう (kan-jō) Meaning: Emotion, feeling — particularly as a general category
In the show: The Eva story hinges on emotional communication — on characters who cannot share their 感情, who are destroyed by isolation.
Everyday use:
- 感情的になる (kanjōteki ni naru) = to become emotional
- 感情を抑える (kanjō wo osaeru) = to suppress one’s emotions
- 感情移入 (kanjō nyū) = empathy, emotional identification
- 喜怒哀楽 (kidoairaku) = the four emotions: joy, anger, sadness, happiness (a set phrase)
6. 恐怖 (kyōfu) — Fear / Terror
Reading: きょうふ (kyō-fu) Meaning: Fear, terror — a profound, physical fear
In the show: Shinji’s defining emotional state. 恐怖 permeates the show — of failure, of rejection, of connection.
Everyday use:
- 恐怖心 (kyōfushin) = a sense of fear, feeling of terror
- 恐怖政治 (kyōfu seiji) = reign of terror
- 恐怖を克服する (kyōfu wo kokufuku suru) = to overcome fear
- 恐怖映画 (kyōfu eiga) = horror film
7. 深層 (shinsō) — Subconscious / Depth
Reading: しんそう (shin-sō) Meaning: The deepest layers — subconscious, profundity
Kanji: 深 (shin) = deep + 層 (sō) = layer, stratum
In the show: Eva’s psychological episodes literally descend into 深層心理 (shinsō shinri) = the depths of psychological experience. The last two TV episodes are entirely internal.
Everyday use:
- 深層心理 (shinsō shinri) = depth psychology, the subconscious
- 深層部 (shinsōbu) = the deep layers
- 深い (fukai) = deep (adjective form of the same 深)
8. 融合 (yūgō) — Fusion / Merging
Reading: ゆうごう (yū-gō) Meaning: Fusion, merging of distinct things into one
In the show: Central to the Human Instrumentality Project — the merging of all human souls. 融合 is both the goal and the terror.
Everyday use:
- 核融合 (kaku yūgō) = nuclear fusion
- 文化の融合 (bunka no yūgō) = cultural fusion
- 融合する (yūgō suru) = to merge, to fuse
9. 補完 (hokan) — Supplementation / Completion of What Is Lacking
Reading: ほかん (ho-kan) Meaning: Completing something that is insufficient — supplementing gaps
In the show: The Human Instrumentality Project’s goal is 人類補完 — completing humanity by eliminating the gaps (the AT Fields, individual isolation) between humans.
The philosophy: 補完 implies that humanity as currently constituted is incomplete. The Project’s horror is that it proposes to fix this by eliminating individuality entirely.
10. 絶望 (zetsubō) — Despair
Reading: ぜつぼう (zetsu-bō) Meaning: Despair, complete loss of hope
Kanji: 絶 (zetsu) = to cut off, to end + 望 (bō) = hope, wish
In the show: Eva is a show about 絶望 — and whether it can be overcome. Shinji’s journey is through 絶望 toward something that might resemble hope.
Everyday use:
- 絶望する (zetsubō suru) = to despair
- 絶望的 (zetsubōteki) = hopeless, desperate
- 希望と絶望 (kibō to zetsubō) = hope and despair (often used as a contrasting pair)
- 絶望の淵 (zetsubō no fuchi) = the brink of despair
11. 自分 (jibun) — Oneself / I / The Self
Reading: じぶん (ji-bun) Meaning: Oneself, the self — a reflexive pronoun but also a philosophical concept
In the show: 「自分が嫌い」(jibun ga kirai) = “I hate myself” — one of the most heartbreaking phrases in the series, and Shinji’s central psychological problem.
Everyday use: 自分 is one of the most-used pronouns in Japanese:
- 自分で (jibun de) = by oneself, on one’s own
- 自分を信じる (jibun wo shinjiru) = to believe in oneself
- 自分らしく (jibun rashiku) = in one’s own way, being true to oneself
- 自分勝手 (jibun katte) = selfish (doing things only for oneself)
12. 覚醒 (kakusei) — Awakening / Activation
Reading: かくせい (ka-ku-sei) Meaning: Awakening — both physical and spiritual
In the show: The moments when the Eva units “awaken” and operate beyond their pilots’ control — 覚醒 signals Eva entering a different, more primal mode of existence.
Everyday use:
- 覚醒する (kakusei suru) = to awaken, to be activated
- 眠れる才能が覚醒する (nemureru sainou ga kakusei suru) = sleeping talent awakens
- 覚醒剤 (kakuseizai) = stimulant drug (literally “awakening drug”)
13. 綾波 (Ayanami) — Ayanami (The Name)
Reading: あやなみ (a-ya-na-mi) Meaning: 綾 (aya) = twill, figured fabric/design + 波 (nami) = wave
The naming: Ayanami Rei’s surname evokes the complex, woven pattern of a traditional fabric combined with a wave — a name that suggests both fragility and depth. She is named after a Japanese battleship (綾波 was an Asakaze-class destroyer).
Cultural note: Anno named characters after WWII naval vessels — Misato (みさと), Ritsuko (律子), and others reference Japanese warships or naval history. This layer of reference connects Eva to Japan’s wartime past and to trauma.
14. 碇 (Ikari) — Anchor
Reading: いかり (i-ka-ri) Meaning: Anchor — the iron device that holds a ship
In the show: Ikari Gendō’s name means “anchor” — the person meant to hold humanity in place. Dramatically, he is more like a weight dragging it down.
Everyday use: いかり also means “anger” (怒り ikari) — same reading, different kanji! Anger and anchor: both things that hold you in place, both potentially destructive.
15. 孤独 (kodoku) — Loneliness / Solitude
Reading: こどく (ko-do-ku) Meaning: Deep aloneness — loneliness or chosen solitude
In the show: Eva’s AT Field is 孤独 made visible — the barrier of self that isolates all people from genuine connection.
Everyday use:
- 孤独感 (kodokukan) = feeling of loneliness
- 孤独死 (kodokushi) = dying alone (a serious social issue in Japan)
- 孤独を楽しむ (kodoku wo tanoshimu) = to enjoy solitude
16. 希望 (kibō) — Hope
Reading: きぼう (ki-bō) Meaning: Hope, aspiration
In the show: Eva asks whether 希望 is possible after everything humanity has done to itself. The ending — controversial as it is — suggests yes.
Everyday use:
- 希望を持つ (kibō wo motsu) = to have hope
- 希望の光 (kibō no hikari) = a ray of hope
- 職業希望 (shokugyō kibō) = career aspirations
- 絶望の反対は希望 (zetsubō no hantai wa kibō) = the opposite of despair is hope
17. 生きる (ikiru) — To Live / To Be Alive
Reading: いきる (i-ki-ru) Meaning: To live, to be alive — as an active, chosen state
In the show: Eva is ultimately about the question of why we live — why choose life over dissolution into a collective unconscious. 「生きていることを許可する」(ikite iru koto wo kyoka suru) = to allow oneself to live.
Everyday use:
- 生きている (ikite iru) = to be alive
- 生きがい (ikigai) = reason for living, purpose in life (one of Japan’s most important cultural concepts)
- 生き残る (ikinokorou) = to survive
- 生きる力 (ikiru chikara) = the power to live, vitality
18. 繋がり (tsunagari) — Connection / Bond
Reading: つながり (tsu-na-ga-ri) Meaning: Connection, tie, bond between people
In the show: What Shinji cannot accept and cannot refuse — the pain and joy of 繋がり with others. Eva argues that 繋がり, despite its pain, is what makes existence worthwhile.
Everyday use:
- 人との繋がり (hito to no tsunagari) = connections with people
- 繋がる (tsunagaru) = to connect, to be connected
- SNSで繋がる (SNS de tsunagaru) = to connect on social media
Famous Line: 「逃げちゃダメだ…」/ “I Mustn’t Run Away…”
The most repeated phrase in the show. Full analysis:
逃げちゃダメだ = 逃げて + は + いけない (compressed)
- 逃げて = te-form of 逃げる (run away)
- ちゃ = colloquial contraction of ては
- ダメだ = “it’s no good,” “mustn’t”
The repetition: Shinji repeats this as a mantra — three times in the first episode, echoed throughout the series. The phrase itself enacts what it describes: Shinji is simultaneously trying to convince himself not to run and failing to fully believe it.
Real usage of ちゃダメ: This construction is extremely common in everyday Japanese:
- 食べちゃダメ (tabe-cha dame) = you shouldn’t eat that
- 忘れちゃダメ (wasure-cha dame) = don’t forget
How to Memorize Evangelion Vocabulary
The emotional cluster: 恐怖, 孤独, 絶望, 感情, 希望 all relate to Eva’s psychological journey. Learn them as a set — they’re also the vocabulary you need for any serious emotional conversation in Japanese.
Concrete + abstract pairings: 心臓 (physical heart) vs. 心 (emotional heart). 生きる (to be alive) vs. 生きがい (reason to live). Eva’s power comes from pairing concrete and abstract.
FAQ
Why did Anno choose Christian imagery for Evangelion?
Anno has said in interviews that Christian imagery was used primarily because it was visually striking and unfamiliar to Japanese audiences — not because of theological intention. However, the concepts he draws on (the soul, instrumentality, apostles) do carry real spiritual weight regardless of intent. The result is a work that Western audiences read as deeply meaningful Christian allegory while Anno himself has described it as somewhat arbitrary visual selection.
What does 生きがい (ikigai) mean exactly?
生きがい is one of Japan's most important cultural concepts: the reason for being, the thing that makes life worth living. It's composed of 生きる (to live) + がい (value/worth). Finding your 生きがい is seen as fundamental to a meaningful life in Japanese culture. Eva is, at its core, a story about characters who have lost their 生きがい and the desperate search to find it again.
Is Evangelion appropriate for Japanese learners?
Yes, but with a caveat: Eva's vocabulary is psychologically rich and sometimes very dark. For learners, it's excellent for emotional and philosophical vocabulary (恐怖, 孤独, 絶望, 感情, 繋がり) that appears in literary and serious conversational Japanese. The first half of the series (episodes 1-13) is more accessible; the final episodes and End of Evangelion are extremely psychologically intense and require comfort with abstract Japanese.
What is the AT Field in Japanese?
AT フィールド (*AT Fīrudo*) = Absolute Terror Field — the barrier each Eva unit (and each Angel) projects. In the show's mythology, all living beings have an AT Field — it's the boundary of the self, the thing that prevents total psychological merger with others. Anno used it to literalize the psychological walls people build around themselves, making the show's exploration of isolation and connection physically visible.
Final Thoughts
Evangelion’s vocabulary is the vocabulary of the human condition: fear, loneliness, despair, connection, hope, and the terrifying question of whether to keep living. These are not anime-specific words — they’re the words Japanese people use to describe the deepest experiences of being alive.
Shinji eventually learns to say 「ありがとう」(arigatō) — thank you. It may be the most hard-won thank you in anime history.
