It is Sunday morning at Japan. Forecast for Typhoon no. 15 seems like same as last night. Looks like airlines has not cancelled flights yet, but JAL is putting Sunday afternoon and Monday morning flights under weather advisory, passengers can change reservation without penalty.

As for Tokyo metropolitan area, forecast is same as last night. Rain and wind will be heavy starting late afternoon and continue till early Monday morning. Best case scenario for tourists is that Typhoon will pass through Tokyo metropolitan area during middle of the night while they are sleep, minimal impact on their schedule. Worse case scenario is that tourists they will be stuck in their hotels on Sunday evening and Monday mornings, difficult to secure meals on Sunday evening and Monday morning.
