Be careful slapping the mat too early. I know you are being encouraged to slap early, and that's fine, but don't make the mistake of slapping too early and trying to "catch" yourself with your arm. The force of the landing can do serious damage to your wrist, elbow, collar bone, and shoulder.
Completely agreed. A number of years ago I met a young girl and her father (they came in as customers in my old workplace), and I noticed that the young girl had both her forearms and wrists in plaster. Turned out she was skateboarding, and came off, and as she fell forwards, she put both hands out to save herself. She broke both her wrists. It may be pertinent to note that she was only about 12, and would have weighed slightly more than a chihuahua, so it wasn't a case of a lot of body weight needing to be supported either.
Our spindly little arms aren't made to catch the full weight of the human body as it slams in to the ground, but the torso is. The rib cage compresses with force, the spine bends, the organs float in a semi-fluid state. As strange as it seems, we are specifically designed to withstand impact to the torso. So that is what you want taking the brunt of the force when you fall, not your limbs and not your head.
Hmm, don't know that I agree with that.... the ribcage is certainly there to help protect the internal organs, but that's a fair way from saying it's there to withstand the impact of a forceful slam to the ground. The throws are actually designed to damage the torso (fracturing ribs, damaging internal organs etc) in their ideal execution, so I'd really advise not looking at the torso as a way of absorbing the impact. The main idea of hitting the ground with your hands/arms is to minimise that impact to the torso... without it, all the force goes into the body, and at best you get winded, at worst some real internal damage.
Slapping helps to disperse the force and absorb some of the impact. But if you put a hand down to catch yourself, you can really get hurt. Be careful! Practicing falls is important, but practicing safely is important too.
Definately true.
As for your problems with Tani Otoshi, have a partner get down on the ground with you in the final position of the throw/fall and work backwards from there. First sitting, then "dipping" with your partner holding you close to the ground and then finishing, and work your way up to the standing fall. If you can land safely with a partner when you're already on the ground, then you can move further and further away from it. I like to start as close to the ground as possible and move away from it, not the other way around. Landing with a partner can be dangerous, you want to make sure you're doing it properly.
This is a way we approach things as well, both in practicing techniques (when it suits) and for practicing the falls themselves. Essentially, a basic way to teach them is to break them into sections, starting with moving/rolling back, then on your back just doing the hand-work, then putting it all together, typically all of this starting from a kneeling height at most. As experience and confidence is built, the height is increased, and later more advanced versions are added.
Thanks for the help, Rob. I notice when I slap, my hands just turn red and hurt; my sensei tells me "slap the mat harder," but that's actually painful too. Who would have thought that the toughest part of learning a grappling art and trying to fall and roll? Sounds like landing on the torso and knowing when to slap will be half the battle in Judo.

Hmm, perhaps something in the wording here, but it may help to stop thinking of "slapping" the ground. That seems to imply a flat hand, which will certainly result in a red, sore hand, so perhaps just thinking of hitting, or impacting the ground may be a better approach. When you do that, ensure that your hands are cupped, so the only parts that actually impact the ground are the edges of your hands and finger tips, as well as the "meaty" part of your arm (turn your elbows away from the ground!) Hopefully that'll help.
