Term for English heading and Japanese body


There seems to be a tendency to have a heading (or emphasized text) in
English, but the body of the text in Japanese.

For example, Tokyo train stations have posters with [Saving
Electricity](http://urbanbrat.wordpress.com/2011/06/30/2011%E5%B9%B406%E6%9C%8830%E6%97%A5-at-
the-train-station/) in English, and the body in Japanese, and [this anti-
groping poster](https://i.stack.imgur.com/A3djh.jpg) only has "NO" in English
(which would only make sense if it's adding emphasis rather than informing an
English-only reader), and [this is an apparent
example](https://i.stack.imgur.com/tCZGW.jpg) of English being used as a
heading or for emphasis.

Assuming that the English isn't for the benefit of foreigners, is there a term
(either Japanese or English) for such English text?




I think there are three variants of this. 1. Translation or summary for the
benefit of foreigners. 2. "Copy" which is there just to make things look
pretty. 3. Words that pretty much became part of Japanese and are used as part
of the Japanese text (words like no, yes, on, off, hello, world etc.).

In the second category, you have 2 sub categories IMO. a) text for the looks,
i.e. lorem ipsum, b) text that is still intended to be read and understand,
and the writer decided to use English for artistic reason.

2-a would be called 文字柄, and 2-b would be コピー or 英語のコピー. Maybe the design
industry has a jargon for this, but I've never heard one before and don't
think there is a word that is commonly used among the general population.
