Milky Way season in Nagoya

• The north celestial pole stands 35.2° above the horizon, so stars within 35° of it never set from here.
• About 78.8% of the whole sky rises above the horizon at some point in the year from this latitude.
• The Milky Way's core in Sagittarius culminates about 25.8° up, staying low, so a clear southern horizon matters.
• At 23 m elevation, roughly 0% of the atmosphere's mass is already below you, which measurably reduces extinction near the horizon.
