Create a high-quality, realistic image of a steaming hot bowl of Japanese Katsu Udon served in a traditional black bowl. The bowl should be placed on a table with a dark green tablecloth. The dish should feature thick udon noodles topped with crispy, golden-brown katsu (breaded and fried pork cutlet), garnished with sliced green onions, a soft-boiled egg, a generous amount of katsuobushi (bonito flakes), and a sprinkle of sesame seeds. Include a pair of chopsticks lifting a portion of the noodles. The background should evoke a traditional Japanese setting with subtle decor elements.
