Hitachi to replace neon lights on Tsutenkaku Tower

Hitachi will replace most neon lights for its advertisements on Osaka's signature Tsutenkaku Tower with light-emitting diodes in a bid to cut electricity consumption by half and contribute to nationwide energy-saving efforts. The LED system, to be lit up starting Oct. 28, will display a greater array of colors and also serve as a bulletin board, displaying slogans and messages selected from public entries.
