The construction sheet of the Aomori Prefecture flag is at www.pref.aomori.lg.jp. The flag ratio is 7x10 (measurements given as 140x200) and gives exact details on what points should be at what locations. Overall, the prefecture symbol is 6.5/10th's of the height of the flag. The only thing that I could not find at this moment is the exact color of the flag. The above law says only dark green and nothing else using Munsell or anything else.

Interestingly, the measurements are given as 140x200 cm, with the comment that the ratio should be kept as 7:10 if the flag is enlarged and shrunk. The law states that the symbol is 65% (literally 6.5 tenths) of the height from top to bottom, and that the base of the symbol is 65% of the flag's width. However, the detail construction sheet does not exactly match this statement. It has the symbol as 9/14 (~64.2%) of the height, and 2/3 (~66.7%) of the width.

Aomori Prefecture is the northernmost province of the largest Japanese island, Honshu. The prefectural flag is a stylized map of the prefecture. If you look at a map of Japan in any atlas, and have the picture of the flag, you will be easily able to recognize that they are of almost identical shape. The proportions are not exact, but if you were familiar with many maps used by the Japanese, it would not come as a surprise.
