Not too bad...you can do it!
Achieve culture or diplomacy victory
Japan isn't the greatest for these victory types, but you can still do it!
Adopt Tradition, Commerce and Autocracy
Tradition, Commerce, and Autocracy can work with diplomatic victory! Makes it hard to get cultural victory. Can still do it but becomes very much harder!
Not have more then 6-8 cities
More cities means it will be harder for culture victory. 4 or less is easier for culture. 6-8 cities is better for diplomacy victory.
Build stonehange to have my own religion (shinto)
Stonehenge isn't required to get a religion. Shinto is not a high priority for any Civ except for Japan, so it should be easy to get Shinto. You can do it even with just shrines! Make shrines in each city a priority if you don't get stonehenge.
With less 6-8 cities you can do it! Use religion choices which give you happy. Try to build cities where there are luxuries, even ones you already have. Be active on trade with AI to buy their extra copies or trade for them. Make friends with happy city states.
Have alot of great people
You can do it! How many is a lot ? You can do it!
Have nukes before everyone else
This is harder but if you focus on technologies that will get you there in the mid game you can still do it.
Overall I'd say diplomatic victory is your best option. Tradition, Patronage, Commerce, Autocracy are the areas I would focus.
Religion choices I would focus on happy and money.
Diplomacy will be important. Focus on city state quests. Try to complete them as much as possible. Keep your spies in city states. Happy ones if you aren't happy enough. Otherwise choose the ones that will help you with defense.
If your science is bad use one spy for a competing civ who is good at science. Once he gets caught, move him to another civ that is good at science. Keep doing this until you can't steal. It will help you get nukes. Don't use spies to protect your cities. Use them for stealing and for city states.
Try not to be too friendly with the warmongers. Be friendly with people who do not aggressive. Focus on building shrines until you get shinto. Then focus on money buildings. Then Science buildings. Don't forget about military! Make sure to have at least 5 ranged and 4 melee until you get to flight. Then you will need planes for defense. This is on same path to nukes so you should get there!
Hooray!
