Benchmarked strictly across TripTiming's 5 empirical pillars: Crowds, Weather, Vibes, Prices, and Safety.
Seoul emerges as the optimal March destination with an overall TripTiming Index of 64/100 vs 60/100 for Tokyo (+4 point advantage). Seoul experiences substantially lower visitor footfall and shorter landmark queues (moderate footfall vs peak seasonal crowding in Tokyo). This is reinforced by lower lodging rates (~$157/night vs ~$261/night, saving ~$728 over 7 nights). While Tokyo retains an edge in Weather Comfort (77/100 vs 54/100), Seoul's commanding performance in Space & Crowds secures the overall March recommendation.
