This is a very pretty fly, it is a pity that it was hardly larger than 2mm.

And I think Gerard better had written in the message text, too, that it is an agromyzid... It is easy to overlook the reply in the message title ;)

Well, if it was not obviously an agromyzid, then the next choice would be a chloropid;) Why is it a agromyzid? Weeell, instinct tell us so, first of all. The 'gut feeling' builds from several small details, none of them very important by itself: details of coloration, head higher than long, head with strong setae on frons (unsharp but visible in the photo), 'fat' abdomen with tubular ovipositor., stance - chloropid normally sit flatter, keeping the body closer to the ground.
off-topic: Woohoo, got my first Stratiomys specimens todayB) after several years spent looking for this impressive soldierfly.:o 2005 is taking shape as an excellent diptera collecting year here in Finland, our mailing list is overflowing with truly exciting finds (new for Europe this, new for science that!)

Kahis, thanks for the explanations! Chtirion: yes, but you can't really see the vertex from this lateral angle..

In addition to Kahis reply: To put it simply: There are not many chloropids that are so strongly setose (both head and thorax) as in this specimen.

Based on Osamu Furuta's opinion this fly could be
Liriomyza huidobrensis (Agromyzidae)
He wrote on the Japanese diptera forum that this species is a recent introduction to Japan, and is considered a pest.
