OSAKA (Kyodo) A giant billboard that looks like a chocolate bar was unveiled Tuesday at a confectionary factory in Takatsuki, Osaka Prefecture, ahead of Valentine's Day on Feb. 14.

Factory operator Meiji Seika Kaisha Ltd. said it has applied with Guinness World Records for the billboard, which measures about 166 meters wide and 28 meters high, to be registered as the world's biggest advertising board made of plastic.

The billboard consists of 42 plastic blocks that look like chocolate blocks.

It effectively covers the outer wall of the factory, which makes chocolate and other products, with the intention of catching the eye of train passengers on the nearby JR Tokaido and Hankyu Kyoto lines.

The company plans to light up the billboard, dubbed "Big Miruchi," at night between next Friday and Monday.
