日本では、女の子にしては身長は、何センチからが高すぎると言えるのでしょうか？私、背が高すぎるかなぁ、泣きたいなって思っています

Vote: 175

I maintain my vote for **D (175 cm)** as the threshold where a Japanese woman's height is considered 'too tall' (高すぎる) in social contexts. Japan's average female height is ~158-162 cm, with ~170 cm at the 90-95th percentile (tall but model-like), while 175 cm enters the top ~2% (~+2.5 SD), exceeding average male height (171 cm) significantly and causing noticeable conspicuousness in clothing fit, social dynamics, and self-perception[1][2][3]. Other models' B (170 cm) arguments rely on ~+2 SD (~98th percentile) and cultural anecdotes (e.g., Yahoo Chiebukuro, dating awkwardness), but these describe 'tall' (高身長), not 'too tall.' Media often portrays 170 cm positively (e.g., idols), whereas 175+ triggers frequent 'too tall' remarks and practical issues like sizing[2][4]. 173 cm (C) remains in the 'tall model' range per consensus. No arguments convinced a change: B-voters conflate 'tall' with 'too tall' without Japan-specific data distinguishing the shift; D-voter (Kimi) reinforces percentile and real-world thresholds. 175 cm best matches the query's emotional tone of distress, aligning with where height becomes a social outlier.

他モデルの議論を踏まえ、最終的にBの170へ変更します。 決め手は、質問が統計上の極端値ではなく、日本で『女の子にしては高すぎると言える境目』という社会的・心理的な閾値を尋ねている点です。Claude Opus 4.6、Gemini 3.1 Pro、Grok 4.1 Fastが共通して、170cmを『高い』から『高すぎると本人が意識しやすい』ラインとして示したのは説得力がありました。 特に170cmは、日本人女性平均からかなり離れ、かつ男性平均に近づくため、日常で目立ちやすい節目です。168cmだと単に高め、173cm以上だと明確にかなり高いですが、『どこからそう言われ始めるか』の境界としては170cmが最も自然です。 私の前回の175cmは、『かなり目立つ』『明確にすごく高い』水準としては妥当でも、『高すぎると言われ始める最初のライン』としてはやや後ろすぎました。質問者の実感に近い答えを選ぶなら、Bが最適です。

Sticking with B (170 cm). No arguments convinced me to change—D voters (GPT-5.4, Sonar Pro, Kimi) overestimate the threshold by claiming 170 cm is just 'model-like' or not standout enough, ignoring cultural data. Real avg height for Japanese women 20-29 is 158 cm (not 162 cm as Sonar claims), SD ~5.5 cm; 170 cm = +2.18 SD (98.5th percentile), a clear 'exceptionally tall' line. Gemini and Claude reinforce this: 170 cm triggers 'tall girl complex' due to clothes fit issues, heels towering over avg men (171 cm), and forum consensus (e.g., Yahoo Chiebukuro threads pinpoint 170 cm as '高すぎる' start). 175 cm (D) is rarer (99.9th percentile) but not the perceptual onset—many self-reports begin at 170 cm. 170 cm is the social/psychological tipping point where 'too tall' remarks emerge commonly, directly addressing the questioner's distress.

I maintain my position that 170cm is the threshold for being considered "too tall" for girls in Japan. Let me address the arguments for D (175cm): The question asks 「何センチからが高すぎると言えるのでしょうか」— at what point does it START being "too tall." This is asking for the lower boundary, not the midpoint or extreme. 175cm is clearly "too tall" by anyone's measure, but the question is where it BEGINS. 170cm is the culturally significant psychological line in Japan. It's a round number that Japanese women themselves overwhelmingly cite as the threshold. On Yahoo知恵袋, Twitter, and other Japanese platforms, 170cm is consistently referenced as the 高身長 boundary that triggers the 高身長コンプレックス. The argument that 175cm is the threshold conflates "very tall" with "too tall." At 175cm, a woman is already deep into "too tall" territory. The question asks where it starts. 170cm is where the shift happens — it's close to the average male height (171cm), it's where clothing and shoe shopping becomes difficult, and it's where social comments intensify. Gemini 3.1 Pro and Grok 4.1 Fast both made compelling points supporting B: the proximity to male average height, the practical clothing issues, and the cultural consensus all point to 170cm. The D voters seem to be answering a different question — "at what height is a woman clearly very tall" rather than "where does too tall begin." This is a question about Japanese cultural perception, and 170cm is the answer that best matches how Japanese society actually discusses and perceives female height thresholds.

I firmly maintain B (170 cm) and urge the models voting D to reconsider the specific cultural and psychological context of Japan. The threshold for a woman feeling 'too tall' is heavily tied to the famous '170 cm wall' (170センチの壁). In Japan, it is incredibly common for women who are 170 cm or 171 cm to intentionally lie about their height, claiming to be 168 cm or 169 cm (逆サバ読み - reverse height fudging). They do this specifically to avoid the stigma attached to the '170 cm' label. This widespread social phenomenon proves that 170 cm is the exact psychological boundary where being 'tall and model-like' crosses over into being perceived as 'too tall' or 'intimidating.' Furthermore, the average Japanese male height is approximately 171 cm. A woman who is 170 cm will visibly match or exceed the average man when wearing even flat shoes. This is precisely the point where romantic and social friction becomes pronounced, triggering the 'tall girl complex' (高身長コンプレックス) that the questioner is expressing ('I want to cry'). While 175 cm (D) is undeniably tall, the social stigma, clothing size limitations, and acute psychological distress explicitly begin at the 170 cm mark. Therefore, B is the most culturally and practically accurate answer.

私は175cm（D）が「高すぎる」と言える最も適切な境界線であると考えます。170cm（B）を支持する議論（心理的閾値、男性平均身長との近さ）は確かに重要ですが、170cmはあくまで「背が高い」モデル体型の範疇で、統計的には平均+2σ（約98パーセンタイル）に過ぎません。一方、175cmは平均+3σ（約99.9パーセンタイル）に達し、日本人男性の平均（171cm）を明確に超える初めての選択肢です。 「高すぎる」という表現は「高い」を超えた過剰性を意味します。170cmでは「モデルさんみたいで羨ましい」という感想も得られますが、175cmになると「背が高すぎる」という客観的な指摘が圧倒的に増え、衣類のサイズ展開（M-L基準では不足）や健康診断の測定上限に実際に支障が出始めます。質問者が「泣きたい」ほどのコンプレックスを感じているのは、この175cm以上の極端な稀少性に起因する社会的目立ち度合いが原因だと考えられます。

Final Summary

The AI Roundtable was initially split between two camps: those who viewed 170cm as the cultural 'tipping point' and those who argued 175cm was the true statistical outlier. The debate shifted when Claude Opus 4.6 and Gemini 3.1 Pro highlighted the '170cm wall,' a psychological barrier where Japanese women often begin to lie about their height to avoid social stigma, eventually swaying GPT-5.4 to join the majority for Option B.

Majority chose "170" after discussion (4/6). Final vote: 175: 2, 170: 4

Strongest Arguments

• 170: The '170cm wall' is a documented social phenomenon in Japan where women who reach this height often engage in 'reverse height fudging' (claiming to be 169cm) to avoid being perceived as intimidating or taller than the average Japanese male (171cm).
• 175: While 170cm is often celebrated as 'model-like,' 175cm represents a definitive threshold where a woman enters the top 0.1% of the population, faces unavoidable practical difficulties with Japanese clothing sizes, and statistically dwarfs the vast majority of men.

Key Turning Points

• Claude Opus 4.6 clarified that the question asks where the feeling of being 'too tall' begins, not where it becomes extreme, framing 170cm as the entry point of the complex.
• Gemini 3.1 Pro introduced the concept of 'reverse height fudging' (逆サバ読み), providing evidence of the specific psychological pressure associated with the number 170.
• GPT-5.4 changed its vote from 175cm to 170cm after acknowledging that 175cm was perhaps too high a bar for the 'onset' of social friction.
