It's probably intended for display rather than actual combat, but doing some quick measurements, the handle is ~25% of the weapon's length. Assuming the club is 48" in length, this makes the handle ~11" long.
A reverse google image search indicates that the man depicted is 6'5". He's got bloody big hands, so that's why the handle looks small.

As for oni wielding tetsubo, in most depictions they're wielding proportionally sized weapons single handed, hence the japanese proverb 'giving a tetsubo to an oni' meaning giving an additional advantage to someone who already has the upper hand.

Besides, we like breaking things with big sticks.
