    Why Zozo Marine Stadium plays differently

    Zozo Marine Stadium sits directly on Tokyo Bay, and wind is its defining feature. Sea breezes funnel off the water and through the open park, and games here regularly play in crosswinds strong enough to visibly move fly balls. Spring games can feel far colder than the Tokyo forecast suggests once the wind comes off the bay.

    Zozo Marine Stadium weather FAQs

    The park is built on reclaimed land on Tokyo Bay with little shelter between the water and the field, so the sea breeze arrives unobstructed, especially on spring and summer evenings.

    Wind direction matters: an onshore breeze knocks fly balls down, while an offshore flow can carry them out. Our NPB temperature, wind and scoring study found that only wind of 20 mph and over measurably moves run scoring (+1.44 runs on 108 games); below that, treat wind as context rather than a measured edge. We publish no NPB wind-direction result because park orientations could not be verified.

    No. It is one of NPB's most exposed open-air parks.
