Good choice
Visit Ota-ku, very nice and historical, also good views
My father died recently, he founded: https://www.densitron.com/contact-us They have offices in Ota-ku, if you visit a Shinto Shrine near there, please say a prayer for him, his name was Cliff Hardcastle. I have inherited his Daruma doll, one eye is already marked, which signifies the start of a journey or ambition. I would like to fill in the other eye to mark its end. I can do this once a prayer has been said for him.
