Izumiya Yoshinosuke, based in Sagano, Kyoto, which sells mackerel sushi and wagashi such as warabimochi, opened on the 23rd in the space beside the Takebashi Station ticket gates on the Palaceside Building's second basement floor and will remain through the 27th. The company touts fatty chub mackerel finished by a painstaking method and says, "It is wrapped in genuine bamboo bark; please enjoy the aroma as you eat."

According to the company, Yoshinosuke's mackerel sushi needs no soy sauce and is known for its firm flavor and fragrance. The sushi, cured in a special blended vinegar, comes in three kinds—cured mackerel, grilled mackerel and miso-grilled mackerel (1,890 yen each, tax included). Each has a distinct taste; the miso-grilled version is a unique "yuzu-miso saikyo-yaki" original. The rice is cooked with thoroughly pursued moisture and humidity control. The mackerel itself is thick, yet cut to a size that is easy even for women to eat—a welcome touch.

Warabimochi comes in two flavors, kinako and matcha uguisu, and the stall also sells shio-mame daifuku, imo-kenpi and mekabu tea. "Please spend a soothing Japanese moment with sushi and wagashi that go well together," the company says.
