sofubi factory in Osaka. The factory is run by Jungle, one of Osaka's largest toy shops. The shop now has a dedicated showcase - the Jungle Artist Collection - displaying many indie toys which they produce. There are figures by Uky Daydreamer, Konatsu, Kaijin, Monster Factory, and others.
Most of the figures are display-only customs, blanks, and production figures, but there are some things for sale, and they will ship overseas. Here are pics of the case:
