Nara by car?

I would try to stop him if I were you. It's expensive just to rent a car, the gas prices are high, and the signs are mostly in Japanese so it's not going to be easy. And I don’t know which side of the road they drive on in your country, but in Japan, it’s the left side. 

I was considering this tour when I visited, which provides a tour and private transport in case it’s difficult for you to use public transport.
