bluefin tuna

The record-high bluefin tuna price at celebratory first auctions in the past was 333.6 million yen (roughly $2.53 million), bid in 2019 by Tokyo's Chuo Ward-based Kiyomura Corp., the operator of major sushi restaurant chain Sushizanmai. That price was equivalent to 1.2 million yen (about $9,100) per kilogram.

these sentences are a part of an original article. 'the operator of major sushi restaurant chain Sushizanmai' part'd disappear from the translation sentences. how could I appear this part. try to modify these sentences under the help of GT. the hint is to delete pebble stone and Magatama which GT'd hate at same time.
