Tropical Storm Yun-yeung, known in the Philippines as Tropical Storm Ineng was a weak tropical storm which affected Japan in early September 2023. The twentieth tropical depression and thirteenth tropical storm of the 2023 Pacific typhoon season, Yun-yeung originated in the Philippine Sea in early September. After exiting the Philippine Area of Responsibility on September 5, it developed into a depression the next day. On September 7, Yun-yeung would peak as a minimal tropical storm before making landfall in Southern Japan. It rapidly weakened once inland, and by September 9, had degenerated into a remnant low.
Despite being weak when affecting the Philippines and Japan, Yun-yeung still produced historical amounts of rainfall in Japan, causing floods and landslides to occur in Southern Japan. A total of three fatalities would be recorded, all in Chiba Prefecture. Total losses are greater than ten million according to Aon.
