Some years ago I went to Myanmar which has a lacquerware craft industry but on a smaller scale to Japan. Its based in Bagan. They use the same lacquer, and dry it with moisture the same way. But they tend to have a damp cellar where they put work in between coats. Its essentially the same technique as Japanese Chinkin - where the design is 'scratched' on a surface and then the scratches are filled with gold (in Japan) or colours in Myanmar.
Here's some pages from a book on their technique which you should be able to zoom into and read, and then pictures of the technique, the tools and some finished pieces.
