Two types of lightning flashes, which are upward lightning and downward lightning, have been observed at Tokyo Skytree. Relationship between upward lightning occurrence and meteorological conditions has been investigated with the data obtained by Japan Meteorological Agency. It has been found that when the altitude of -10°C is lower than 6000m, most of lightning flashes are upward and vice versa.
