Thanks !
How did I do it ? Well, I looked for KMI in Izumi, Osaka.
Amongst the results were the full registration information for a now-defunct website called auto-kmi.com. The company who registered that site was labelled as "Komyouike".
9 letters instead of 10 but it more or less fitted with the pattern you gave. A search with "Komyouike" was fruitless,
but the website registration information also contained an address : 1208-3 Murodocho. Thanks to that I found the correct Koumyouike company in a German (!) business directory. Searching for Koumyouike KMI eventually led to the company's current website.
