"MIO1" has a blue/green border with floral sprays and gold trim. I wasn't able to find much information concerning the company that produced Mikado China, but Mikado meaning is a title of the Emperor of Japan. Since the bottom mark states 'Made in Japan' means that this was produced between 1915 - 1945, when Japan started using Japan [rather than Nippon] or Made in Japan. After 1945, the mark would state Made in Occupied Japan. No chips or cracks. 6 1/2"
