Beat the 'Extreme Heat Days' with Chinese 'Sourness' to Regain Lost Appetite! [Chinese Ramen Yangzhou Shonin] Three types of chilled noodles, which sold over 48,000 servings last year, to be released from May 11 (Monday).

[Limited-time release on 5/11] Yangzhou Shonin's three types of 'chilled noodles' appear, challenging the intense heat with authentic Chinese techniques—chilled ramen with ice and secret sourness, available at 38 stores in the Tokyo metropolitan area.

Whistle Miyoshi Co., Ltd. (Headquarters: Suginami-ku, Tokyo, Representative Director and President: Ichitaro Miyoshi), which operates 'Chinese Ramen Yangzhou Shonin,' will begin selling three types of summer-limited menus—'Chilled Tomato Noodles,' 'Chilled Black Vinegar Noodles,' and 'Chilled Chicken Soba'—starting Monday, May 11, 2026. These three types combined sold over 48,000 servings last year.

Among them, 'Chilled Tomato Noodles,' which sold over 21,000 servings last year and boasts the top sales in the series, is a summer symbol of Yangzhou Shonin. Its pleasant texture of ice-chilled ramen and the contrasting textures of overlapping ingredients awaken a summer-fatigued stomach.

■ Challenging Japan's new threat, 'Extreme Heat Days,' with the power of food

Background: Summer, when appetite declines due due to heat.

In 2026, the Japan Meteorological Agency officially adopted 'Extreme Heat Day,' referring to a maximum temperature of 40℃ or higher, as a formal forecast term. With the Japan Weather Association also predicting its nationwide occurrence, Japan's summers are becoming increasingly severe each year.

With recent record-breaking heat becoming the norm, how can we overcome the 'loss of appetite due to heat' and 'heaviness of the body' that everyone experiences? Yangzhou Shonin focused on the power of 'sourness' and 'aroma,' which have been cherished in China since ancient times.

Not just simply cold, the pleasant texture of ice-chilled ramen and the calculated 'sourness' unique to authentic Chinese cuisine allow the noodles to pass refreshingly down the throat and fill the stomach, even on days when one has no appetite. We propose these three dishes with the hope that people can overcome the harsh summer heat with the joy of food.

■ Product Lineup: Three 'Exquisite Cool Delights' to overcome the intense heat

1. [Undisputed No. 1 Popularity] Chilled Tomato Noodles

~A contrast of textures created by ingredients that combine softness and chewiness~

This bestseller recorded the highest sales among the three types last year. The three different textures stimulate a stagnant appetite, and the vivid red of the tomatoes brings coolness visually, making it an enduringly popular summer menu item.

Calculated texture: 'Domestic salad spinach' with both softness and crispiness, juicy and tender 'pork,' and 'diced tomatoes' hidden in the cold sauce. The contrasting textures of these three ingredients enhance the deliciousness and enjoyment in the mouth.

Golden ratio of sourness and sweetness: Tomato soup with sweetness added to sourness from vegetable extract, drizzled with rich sesame oil, highlights the refreshing yet profound authentic Chinese flavor.

2. [Rich Black] Chilled Black Vinegar Noodles

~Authentic Chinese black vinegar and Sanmeitan accelerate appetite~

This dish combines authentic Chinese black vinegar with the traditional beverage 'Sanmeitan (Sour Plum Soup),' creating a concentrated flavor of sourness and umami. The power of 'sourness,' instinctively sought by a body fatigued by extreme heat, strongly awakens the appetite.

3. [Elegant White] Chilled Chicken Soba

By blending 'Zaolu,' a traditional Chinese fermented seasoning, into the 'Chintan (clear) soup' condensed with chicken umami, it achieves a profound aroma and richness not found in other noodle dishes. It is refreshing yet deep, stimulating an appetite dulled by the heat.
