In English, if you have a poem, like
Roses are red,
Violets are blue,
Sugar is sweet,
And so are you.
and you need to write it on just one line (for reasons of space or whatever), you would write it like this:
Roses are red, / violets are blue, / sugar is sweet, / and so are you.
That is, you use a single forward slash to separate the lines of the poem.
What is the equivalent of this in Japanese? I know that in some cases, you can just omit the line breaks altogether, e.g. writing
But supposing you did need to indicate the line breaks, how would you do so?
