Mr Ghosn is believed to have fled the country inside a crate used to house audio equipment, which was put on a private jet that flew from Osaka to Istanbul, before flying to Beirut, Lebanon, in December.

Tales of his escape have apparently prompted a number of enquiries about the ability of instrument cases and the like to house a human.

"We won't mention the reason, but there have been many tweets about climbing inside large musical instrument cases," Yamaha's Wind Stream account tweeted.

"A warning after any unfortunate accident would be too late, so we ask everyone not to try it."

"Instrument and audio equipment cases are designed to hold musical instruments and audio equipment. Please use them correctly," a follow-up tweet read.

Mr Ghosn is accused of hiding earnings, transferring investment losses to Nissan and misappropriating company funds.

Japanese authorities have vowed to pursue him and have issued an international wanted notice for him and his wife Carole.

The former auto executive and fugitive has declined to reveal how he slipped past Japanese airport security, or confirm media reports accomplices smuggled him through a private jet lounge in Kansai Airport in western Japan hidden in a large speaker box that was too large to fit through the facility's x-ray scanner.

Earlier reports, which Ghosn has dismissed, said he was carried out of his home in Tokyo in a double bass case.

Yamaha, which makes instruments and equipment ranging from pianos and double basses to drums and heavy duty speakers, thanked people in a second tweet for liking its first post, which was retweeted more than 50,000 times.
