Nara Palace Site Historical Park
It was a place that flourished as the capital of Japan when the imperial palace was moved to Heijo-Kyo in 710. It is said that more than 100,000 people lived in the large-scale capital of about 2,500 ha, which was modeled on Changan, the capital of Tang.
It's completely deserted and not easy to get to! I wouldn't recommend it.
