Right after a nice and easy exam done this morning, i wanted to give a try with Japan. This civ is THE perfect civ to go through sub 90 turns and WITHOUT lucky ruins. First roll of map with this civ too 
Won turn 92. But here is some pics why it made me lost 5-7 turns.
Here you can see west of map a nice wall of city states and mountains.
Here is the left of my capital, after i have throwed my second army. Many 1 tile turns and a damn well placed barb camp.
I lost a turn to settle on gold. Got a money ruin and a culture ruin, but when i popped a free settler he waited in capital for almost 20 turns. So culture or not it was my strat to pop a settler for turn 60. With an extra monument from the first conquered city, i would have got that settler in time.
100% attack when damaged is perfect for city attacking and you can gather more insta-heals when you don't want to lose time for last turns, when swords are about to kill the last civ(s). Well it was a part of my strategy.
Part of credits goes to walkerjks. Thanks dude, great plan. Sub-85 is possible with this civ, even more if you get eldorado.
