Japan's space agency said on Friday that the new flagship H3 rocket failed to lift off as scheduled on the day due to an ignition failure.

Japan's first H3 rocket failed to launch from the Tanegashima Space Center in Kagoshima prefecture on Friday morning after the booster engines were unable to ignite, according to the Japan Aerospace Exploration Agency (JAXA).

The agency said it is investigating the launch failure, Xinhua reported.

The launch of the H3 rocket, Japan's successor to the H2A rocket, its previous mainstay launch vehicle, was initially planned for February 12 but delayed to February 15 owing to a glitch in the rocket's flight system, and then again pushed back to February 17 due to unfavourable weather conditions.
