1. Their home addresses

# desc. addr.
1 Their former home address before they moved to some place which I have never visited
UPDATE: According to the registered information for this property [PDF] it is likely that they had lived there until they left it in September, 2020.
大阪府 八尾市 老原 3丁目4番10
2 The update which my dad has sent to me 大阪府 八尾市 東太子 1-5-30
3 The one which I have obtained by sending an inquiry to the city which holds the information Feb. 28 UPDATE: According to this [JPEG image] it's 大阪府 八尾市 東太子 1-5-30. Still I cannot believe this but a close look at the mailbox that appears on Google Street View tells me that it's of Miyajima (宮島) so maybe it's really Miyajima's house.

2. The one which I want you to inspect directly

As shown above, it's: 大阪府 八尾市 東太子 1-5-30

It should look like this according to Google Maps. But I'm highly skeptical that they actually live in this building even though my dad says that he has bought it at a very reasonable price from a real estate agent who is his friend, that it was formerly a delivery station of Asahi Shimbun newspaper company and he converted it into what is suitable for living, etc. So I request you and your family members to check whether my parents really live there or not.
