うわべ・上辺uwabe[0]heiban (flat)

1. nounexterior; surface; outside
   彼かれは彼女かのじょのうわべだけの好意こういにだまされた。↗

   He was deceived by her apparent friendliness.
2. nounoutward appearance; looks

• Synonym表面ひょうめんNeutralThe plain, objective surface of a thing, as in 「月の表面」. 「上辺」 adds a disapproving nuance of a showy front put up for appearances.
• Synonym外面がいめんWrittenWritten word. As 「がいめん」 it is the outer surface of an object; as 「そとづら」 it is one's outward manner. 「上辺」 stresses a showy front.
• Synonym表おもてNeutralThe visible side or front of something, and by extension public settings. Neutral: it does not carry 「上辺」's hint of pretence.
• Synonym外側そとがわNeutralThe outside or outer side, a purely spatial term. It has none of 「上辺」's suggestion of a front kept up for show.
• Synonym外観がいかんWrittenWritten. The outward look of something, said most often of buildings. Neutral in tone, without 「上辺」's tinge of pretence.
• Synonym外見がいけんNeutralHow a person or thing looks from outside, in a fairly objective way. 「上辺」 carries the extra suggestion of something false or put on.
• Synonym表層ひょうそうWrittenWritten and academic: the surface layer of something, as in 「表層意識」. It names a layer, not a showy front.
• Synonym見せ掛けみせかけNeutralA false front, mere posing or pretence, with a disapproving tone. Very close to 「上辺」 in pointing to what only seems real.
• Synonym外装がいそうNeutralExterior fittings or packaging — the outer structure or dressing of buildings and products.
• Synonym上っ面うわっつらCasualColloquial for the surface, usually with a critical edge, as in 「上っ面だけの知識」, knowledge that is only skin-deep.
• Related見かけみかけNeutralOutward appearance, typically set against what is really there, as in 「見かけ倒し」 (all show and no substance).
• Related格好かっこうCasualColloquial: how someone or something looks — shape, dress, get-up. It does not stress pretence the way 「上辺」 does.
• Related装いよそおいWrittenWritten: attire or dress, as in 「春の装い」. It suggests an attractive, considered look rather than a hollow front.
• Related一皮ひとかわNeutralA thin outer layer that hides the true self; often in 「一皮剥けば」, stripping off the veneer to reveal what is underneath.
• Related見栄えみばえCasualColloquial: how good something looks — being presentable or attractive. It is a positive judgement, unlike the critical 「上辺」.
• Related上面うわつらWrittenWritten: the surface, close to 「上っ面」 and carrying a disapproving shade — appearance without substance behind it.
• Antonym奥おくNeutralThe depths or inner part of something — the opposite pole to 「上辺」's surface.
• AntonymうちNeutralThe inside, including one's heart, as in 「心の内」. It stands for what is within, against 「上辺」's outward show.
• Antonym裏うらNeutralThe same word as 内, also written 「裏」 or 「中」: the inside or one's true feelings, opposed to 「上辺」's outward appearance.

For a physical surface say 「表面」; 「上辺」 is for the show someone keeps up, as in 「上辺だけの言葉」「上辺を繕う」. For outright pretence use 「見せ掛け」; for what lies within, 「奥」 or 「内」. Neutral looks: 「外見」「見かけ」. Written: 「外観」「外面」「表層」「装い」「上面」. Colloquial: 「上っ面」「格好」「見栄え」. 「外側」「表」「外装」 are concrete or spatial; 「一皮」 is the veneer you strip off.
