Commonly used term(s) for floor/ground/whatever surface we usually stand on


I've had trouble communicating the concept of 'doing something on the
floor/ground' in Japanese. I've seemed to miss the mark by whichever word I
used for the situation during several short conversations. In addition, when
the other party referred to the floor I couldn't grasp what exactly they used
so I can't learn from it (I'm not good at listening comprehension in general).

Examples while talking about games for children:

Q 'Do you need any tables or ..?' A 'No, this game should be played on the
ground.'

'When you hear the signal, everyone needs to [activity] on the floor.'

I have found the following words, but I simply don't know anything about their
actual usage.

  * 床 {ゆか} 
  * 床面 {ゆかめん} 
  * 地上 {ちじょう}

床面 and 地上 seem to earn some luke-warm smiles when trying to use them, whereas
床 is usually not understood at all after which I switch to one of the other
two.

I also feel that Japanese people tend to use other terms as well when they
refer to what I said. I just can't acoustically retain these to look them up
later. These are not conversations where I have the leisure to ask for
clarification either, due to time constraints mostly.

So with that, **is there any general-purpose word for floor/ground that is
appropriate whether you may be in a building or outside, in a tatami room or
in a swimming pool, etc.? If not, what are the most common terms for these
kinda things?**

[This question and
answer](https://japanese.stackexchange.com/questions/14131/what-are-the-
differences-
between-%e5%ba%8a-%e5%ba%8a%e4%b8%8a-and-%e5%ba%8a%e3%81%ae%e4%b8%8a) seems to
suggest 床 is nothing unsual, but since it doesn't match my experience I felt
the need to ask anyway.




I think that there is no common Japanese word equivalent to "floor" or
"ground".  
Actually, as shown in the following examples, words are used properly
according to the situation.

As for this theme, there is only one thing important as Japanese language. In
Japan, as you know, there is a custom to take off footwear in the house in
general, so even if we don't remove shoes in the office there is a sense
perception that the floor of the office is cleaner than the outside ground of
the office, and in the wording equivalent to the floor or in the
representation of phrases including floor there might also have some effect
according to this custom, though I couldn't introduce good examples.

  1. In case of "[板の間]｛いたのま｝ _a wooden floor_ " 

    * 板の間に座{すわ}る
    * 板の間に座ると冷{つめ}たい。
    * 板の間に直{じか}に座ると冷たい。
  2. In case of "畳{たたみ} _tatami mat_ "

    * 畳の上｛うえ｝に座る = 畳に座る
    * 畳に座布団{ざぶとん}を敷｛し｝いて座る
    * 畳に直{じか}に座る
  3. In case of a carpet/rug 

    * 絨毯{じゅうたん}/カーペットの上に水｛みず｝をこぼした
  4. In case of not minding the material of the floor 

    * 床｛ゆか｝に座る = 床の上｛うえ｝に座る
    * 床に物｛もの｝を置｛お｝く = 床の上に物を置く
    * 通行{つうこう}の邪魔｛じゃま｝になるので床の上に直｛じか｝に物を置かないでください
    * "床暖房｛ゆかだんぼう｝ _floor heating_ " は暖｛あたた｝かさが自然｛しぜん｝で良｛よ｝い
    * 床暖房は足元｛あしもと｝から温｛あたた｝まる
  5. on the groud of the park or roads not paved 

    * 子供｛こども｝の頃｛ころ｝、地面｛じめん｝に線｛せん｝を書｛か｝いて遊｛あそ｝んだ
    * 土｛つち｝の上/地｛じ｝べた/地面｛じめん｝に直｛じか｝に座｛すわ｝ると服｛ふく｝が汚｛よご｝れるよ
  6. a paved park or roads

    * 財布｛さいふ｝が地面｛じめん｝に落｛お｝ちていた
    * 道｛みち｝で財布｛さいふ｝を拾｛ひろ｝った
    * 日本｛にほん｝では、道路｛どうろ｝にゴミを捨｛す｝てる人｛ひと｝はほとんでいない
    * 舗装｛ほそう｝している道路｛どうろ｝でおしっこ/立小便｛たしょうべん｝したらこちらに流｛なが｝れてきて困｛こま｝ったよ
    * 夏｛なつ｝は公園｛こうえん｝のアスファルトが融｛と｝けそうなほど暑｛あつ｝い
  7. a school playground or a park square 

    * 学校｛がっこう｝の運動場｛うんどうじょう｝でサッカーをした
    * 公園｛こうえん｝の広場｛ひろば｝で犬｛いぬ｝が走｛はし｝っていた
    * サッカー場｛じょう｝のグラウンドに水｛みず｝を撒｛ま｝いている




When outside I think we normally use [地面]{じめん} (or colloquial/slangy
[地]{じ}べた), when inside a building, [床]{ゆか}(の上), and in a tatami room,
[畳]{たたみ}(の上). In a swimming pool, you'd use (プールの)[底]{そこ}.

> Boden  
>  ❷ **地面** ； **床** ▷auf dem Boden sitzen 地面〈床〉の上に座っている  
>  wird der Boden unter den Füßen zu heiß ～の **足元** に火がつく*  
>  ❸ **底** 、底面 ▷der Boden des Meeres 海底  
>  （三修社『アクセス独和辞典』）  
>  *I think it's a literal translation. It seems the phrase is an idiomatic
> expression that figuratively means 「状況が悪くなって、そこにいづらい・いたたまれない」("things got
> too hot and you can't keep standing / can't stay there")

> Boden  
>  2 **地面** ； **床** er verlor den Boden unter den Füßen 彼は **足元** がぐらついた.  
>  5 （海、船、樽などの） **底**  
>  （郁文堂『独和辞典』）

I don't think we have a general-purpose word for floor and ground (+ tatami
room and the bottom of a swimming pool)... That said, in casual/colloquial
conversation, I think we sometimes use 地べた for floor as well when you're
inside a building, especially where you wear shoes (though this might be just
in Kansai??). And depending on the context, I think you can also use [下]{した}
or [足元]{あしもと}, as in 「カバンは[下]{した}に/[足元]{あしもと}に[置]{お}いてね。」

> 「[机]{つくえ}か[何]{なに}か[要]{い}る？」  
>  'Do you need any tables or ..?'  
>  「いや、このゲームは[地面]{じめん} (or [地]{じ}べた or maybe [下]{した}) でやるやつだから。」  
>  'No, this game should be played on the ground.'

> 「[合図]{あいず}が[鳴]{な}ったら、[床]{ゆか} (or [下]{した}) で/に～～ましょう。」  
>  'When you hear the signal, everyone needs to [activity] on the floor.'
