I received an invitation a few months ago and finally had the chance to visit Sushi Saitou for a private reservation.Amidst a serene atmosphere, lively calls filled the air. After a few appetizers, the sushi began.On this day, the sushi chef was Ishikawa.We started with appetizers, which were exquisite and heightened my anticipation for the sushi to come. That anticipation quickly turned into certainty. The carefully selected seasonal seafood, along with the temperature of the rice and its melt-in-your-mouth texture, created a perfect harmony with each piece, showcasing exceptional quality.Particularly memorable were the horse mackerel, kohada, and sea urchin. The horse mackerel was rich in fat, and while the quality of the ingredient was evident, there was something uniquely different about it that I can't quite describe. The sea urchin was impressively large and luxurious, easily imagined to be quite expensive for just one piece. It was rich yet surprisingly elegant in its aftertaste. I was moved by how well the chef brought out the essence of the ingredients. The kohada was perfectly vinegared, and it was the best I've ever had.While the price point is certainly not casual, the experience was worth every yen. This was truly remarkable sushi that reaffirmed the quality of Tokyo's seafood.Here’s what we had that day:The following items are appetizers (＊) and the rest are sushi (○):＊Hon-Ara (Grouper)＊Tender Octopus - unbelievably tender＊Steamed Abalone - exquisite!＊Fatty Tuna Braised - melts in your mouth＊Salt-Grilled Nodoguro (Blackthroat Sea Perch)＊Mozuku (Seaweed)○Flatfish＊Gari (Pickled Ginger) and Wasabi Stems - the gari was quite vinegary, and I choked on it a few times.○Aori Ika (Bigfin Reef Squid)○Kohada (Gizzard Shad) - delicious with a sharp vinegar flavor○Marinated Red Meat Tuna○Fatty Tuna○White Shrimp○Torigai (Surf Clam)○Horse Mackerel - I was amazed by the quality of Tokyo's light fish!
