Unless I am mistaken --- you have Fugu on the brown plate - at high center of your picture...
Had it served to me once -- in Nagoya.
We were told it was the same restaurant where a famous Japanese actor committed suicide in front of his friends by intentionally eating the most deadly portion of the fish..which he ordered to be brought from the kitchen.
The "safe" pieces of Fugu had absolutely no taste - in my opinion...
I believe it to be a "status" or "impression" dish, more than anything else...
In Japan, the very best Sushi is to be found in the small, popular neighborhood Sushi Restaurants..... They rely on return business from the neighborhood residents -- and they are more comfortable, friendly and appreciative of your business.
One of the MOST delicious and surprising meals I discovered- was Unagi Donbori. Barbecued ell with a delicious unique sauce, served over a bowel of rice. Here again, the best to be found was in a small neighborhood restaurant in a small town near Nagoya.
Even after nearly 50 business trips to Japan - I never tired of the wonderful and vast selection of food. It is one country in the world - that I felt perfectly safe in eating whatever was placed in front of me - or found being sold on the street...
