Raikkonen got out of shape at Degner 2 and slid through the gravel into the tyre wall mid-way through the final practice session at Suzuka, with his car having to be lifted back to the Ferrari garage.
Further inspection revealed gearbox damage, forcing the Scuderia into action - and with the change coming before six consecutive events, a five-place drop is a formality.
Raikkonen is not the only man facing a penalty for Sunday's grid: McLaren's Fernando Alonso is set to start from the back of the field after a cumulative 35-place drop, while Renault's Jolyon Palmer has his own 20-place drop to contend with. Toro Rosso's Carlos Sainz meanwhile also faces a 20-place drop.
