A little over a month has passed since the smartphone game "Pokemon Go" was released in Japan, but people are still found wandering around Nagoya's Tsuruma Park — a magnet for its players — until late at night.

Pokemon fever has ebbed slightly, but people now gather there even if there are no events, and nearby stores are enjoying strong sales of items related to the game.

Many teenagers are caught loitering in the park at nights, forgetting the time as they devote themselves to capturing the virtual monsters central to the game.
