After reasonably succesful till turn 150, I finally gave up at turn 250.
In opening thread I described my conquest of Polynesia, and was heading for Karakorum. Mongolia was easy to kill and so I thought about Japan. I approached from the south with a plan to chop that 1 forest unlocking more CKNs to strike, but never done it. Bascally every 3-4 turns a wave of 3 samurais was emerging and due to Great Wall I was never ready to kill even 2 of them in 1 tur. However there were able to one hit me (tooltip said 41 strength) , I lost too many units and 2 or 3 GG, and when finally I thought Kyoto is on 0 health and can be taken by haevely injured sword, it occured it was not

Decimated, at 2 melees and 5 CKNs left I white peaced because another wave of Samurais was coming.
So I turned to England and was very succesful killing many units using the strait and was just to embark, when Japan declared, even though I kept them constantly at war witz Zulu, followed by Siam, which already had basically every CS alled.
Meantime Zulus killed Assyria and their army was close enough and I knew their "Friendly" means nothing.
Yes, I could keep fighting England, allow Japan to take Karakorum and go back later, but that is too time and nerves engaging, espacially that Siam became a real monster and at the end I would rather expect them launch before I even reach their border, and I don't think I would have enough strength to slowly move into their teritory.
No.... Deity domintaion against so many civs is not for me yet

Even with China
I am pretty sure if I reloaded my t150 and with a knowledge of the map I would succeed - I would simply move early toward England, as both capital were so close to each other. Killed England and Indonesia = more troops for long trip to the east. Lack of proper scouting = fail
