Against back kick, what I share today is one of the ideas. Use both hands and slap the kicking leg down. Then, the opponent's back is facing you. You can quickly execute the counter strikes.
The key point is to step in as soon as the attacker rotates his body and while his back is facing you.
Be sure to go slightly outward, so that you can dodge the kick easier, i.e. to 1 or 2 o'clock if you are stepping in with your right leg.
Of course, we can use the other (two) techniques that I have already shared this week.
One option was Gyaku nagashi uke 逆流し受け, and punch with the front fist.
The other option was Sukui uke 掬い受け and to grab the leg and take him down.
