「さようなら」。 "Sayounara."
Also: Stroke order is easy. It's the same for every kanji. You write the sections ("radicals") left-to-right, top-to-bottom, and in each section you write the strokes left-to-right, top-to-bottom. The top and right strokes of box-like shapes is a single stroke (like writing the number 7). The only tricky part is knowing when the left and bottom sides are one stroke (like the example below) or two (as in a box) -- and that's just a matter of practice; usually you can tell by the shape of the character. Once you get used to thinking of it this way, you'll be able to write unfamiliar kanji without even thinking about it.
Let's look at this character (tatsu, "dragon"). Looks scary! But it's not. First you do the five-stroke piece on the top-left, then you do the four-stroke piece on the bottom left. Then the really scary-looking part on the right goes in this order:
* Short vertical stroke
* First horizontal stroke
* Second horizontal stroke connected to short vertical bit
* Third horizontal stroke
* Long vertical stroke connected to tail at bottom
* Fourth, fifth, and sixth horizontal strokes
