Where is Nara?
About 75 miles north of Tokyo.
Never mind - I’m thinking of Nakka. Nara is down near Osaka.
It’s about 30 miles south of Kyoto and 30 miles east of Osaka - it’s known for being the first real area of concentrated Japanese culture. The leader during that era, Shotoku Taishi @600AD instituted many reforms that lead Japan into the later Heian era in Kyoto. If the plate is from the Romans, it was probably brought from the Chinese or Koreans. The Japanese worked intensely during that period to import technology, especially metallurgy.
About 3 miles up the road in Chino Hills, CA. Literally just finished up my Teryaki Salmon and Sushi Combo Dinner.
I kid you not. It's better than it's Yelp rating.
