Are these Japanese owned/ Japanese chefs? Or Korean/ Chinese owned/ operated?

Had a bad experience at a place called Sushi Bada in Suffern, NY. Haven’t seen nigiri that badly skimped/ small, too heavy handed in terms of rolling/presentation. They charged per single piece, but charged what you normally pay for 2. Quality was mediocre overall.

Example- ikura- $8.25 per piece- very, very light on roe.

Uni- $9.00 per roll. Very light on the uni- also looked like what you buy from Hmart.

Maguro- $4.80 per roll- sliced so thin it was see through.

Otoro- $9.00 per roll- same- sliced super super thin.
