It's using Japanese in a meme about Chinese history.
The uniform spacing tricks my eyes to think it's written vertically (i.e. start from top-right, move down the column, move left to the next column), but it's actually written horizontally, just like the text you're reading right now. The first time I saw this image, it made me believe the text was pseudo-Japanese gibberish, but it looks more like something you'd get if you used machine translation.
