How do you say "I'll be back" in Japanese?

This is a picture of typical "o-miyage" that you can find all over Japan. "O-miyage" is what you give to your colleagues when you return to work from a vacation or business trip or whatever. Buying a box of o-miyage usually means that you are buying a box of some sort of individually wrapped cookie or tiny cake. Whenever you return to work, you simply put the box in the designated area and let your colleagues dig in as they please. And since in Japan teachers constantly go out of town on business or whatever, nary a week goes by when there isn't at least one box of o-miyage. And since the idea is to bring back a product that is typical for the area you visited, you get to try all sorts of different goodies, depending on where people went. I've already had rather delicious junk food from Okinawa, Osaka, and Fukuoka, for instance.

What's funny about the o-miyage pictured here is that they all have a picture of "Chigi-san" on them. Chigi-san is the Arnold Schwarzenegger of Miyazaki prefecture. I don't know too much about the guy, except that he used to be a comedian on TV. And now he's the head of the prefecture! From what I understand, since he's taken over (early this year?), he's been doing one hell of a marketing job. Miyazaki is growing and growing in popularity, and people flock from all over Japan to Miyazaki to catch a glimpse of "Chigi-san." His caricature is is plastered on everything in these parts from the o-miyage pictured above (some of the cookies even have his likeness stamped on them!) to key chains, fans, and even piggy banks. Believe me, he's popular! And like I said, he's trying his darndest to popularize Miyazaki products, one of which is the mango.

He even welcomed us at our orientation a few weeks ago in Miyazaki city. As we waited quietly in this nice room in one of the prefectural administration buildings for him to appear, we suddenly heard a bunch of shrieks. Obviously, the man was on his way. He arrived seconds later and promptly proceeded to give his speech. He started off in English but eventually switched to Japanese. And before we knew it, he was gone (to more shrieks from the public waiting patiently out in the hallway).

In any case, when it was time for our lunch break, we, too left the room, just as Chigi-san had. And what do you know? There were about 100 people lined up on both sides of the grand stairway, cameras in hand, patiently waiting for Chigi-san, obviously. Well, thinking fast, I decided to put on a little show for the crowd. I pretended they were all waiting for me so I started waiving to them all. And then I pretended for a few seconds to give a speech, yelling out a few quick thank-yous, waving some more, and posing for pictures. The crowd seemed to like it, believe it or not. Then I went on down the stairs, waving some more, saying "Hi" and "Thank you" and whatnot and shaking some hands here and there. I felt a little ridiculous but still tried to enjoy the moment that really wasn't mine!
