I would definitely second the suggestion to look into graded readers. This thread details the main graded readers available - the ones usually recommended are published by Ask, or the White Rabbit eBooks.
Levels zero and one are really very easy; if you find that you can’t manage the lowest levels of these yet, I’d recommend focusing on just a bit more grammar study before you start trying to read things (I’m actually rather of the opinion that level zero is a bit of a waste of time anyway).
You’ll also see in the OP of that thread a link to the Japanese Tadoku association, which has a selection of free graded readers available. The quality isn’t as high, but graded readers are quite expensive.They are probably also a good way of gauging your level before splurging on a paid set, or reading some free level zero / level one texts before buying some level two +.
