Tokyo authorities issued Level 4 flood-danger warnings for five rivers on Wednesday as Typhoon No. 6 brought heavy rain and strong winds [1].
These warnings signal a critical risk of river overflows, requiring immediate evacuation or safety measures for residents in affected areas to prevent loss of life.
The alerts cover the Zenpukuji, Kanda, Meguro, Nogawa, and Sen川 rivers [1]. According to reports, the warnings in Tokyo were issued at 10:05 on June 3, 2026 [1]. The weather system is driven by the approach of a large typhoon, which has caused water levels to rise rapidly across the metropolitan area [1].
A reporter from TBS NEWS DIG provided a live update from a footbridge near the Zenpukuji River in Suginami Ward. While the Level 4 warning remained in effect for the area, the reporter noted a shift in the river's condition.
"I am here near the Zenpukuji River in Suginami, Tokyo, where a Level 4 flood-danger warning has been issued," the reporter said [2].
Despite the active alert, the reporter observed that the immediate threat at that specific location appeared to be easing. The reporter said, "Currently, the water level is falling" [2].
Local authorities continue to urge residents to remain vigilant. Level 4 warnings typically indicate that a river is at imminent risk of flooding or that levees may breach, a situation that demands urgent action from the public to reach higher ground or sturdy shelters.
“Currently, the water level is falling”
The issuance of Level 4 warnings across five major Tokyo waterways simultaneously indicates a systemic threat to the city's drainage and river management systems during Typhoon No. 6. While the receding water levels at the Zenpukuji River suggest a temporary reprieve in some wards, the broad geographic spread of the warnings highlights the vulnerability of Tokyo's urban river networks to extreme weather events.
