The Hyatt Regency Hakone Resort & Spa will participate in Japan's "Carbon Dioxide Reduction Light-Down Campaign' by turning the lobby lights off for two hours on June 21 and July 7. The Hyatt will also be lighting its lobby fireplace with candles, instead of a fire, between June 21 and Aug 31. The "Carbon Dioxide Reduction Light-Down Campaign' was started by the Ministry of the Environment to help reduce carbon dioxide emissions and encourage thoughts about how to prevent global warming.
