Thank you for the information! I have heard of a JA list floating around but have not seen it. My friend in Japan probably just researched Kenmore in Japan and went with the first thing that came up. I do have a few 158 Kenmores. So they are the ones from Maruzen most likely? My mom has a Kenmore 158.17821 that she loves. She's who got me started with Kenmores. I was so excited to find this one! I had been looking for a Kenmore HA-1 and thought it would be slightly bigger than this one so didn't think this was one until I spoke with my friend in Michigan. I am thrilled to have one now. : )
