Stool softener? (constipation)

I am looking for a stool softener containing docusate (ドクサート
or ジオクチルスルホサクシネート in Japanese). I do not want a laxative which forces you to poo, just something to soften stool.

I have tried コーラック2 which contains docusate, but also acts as a laxative by forcing you to poo.

Is there any OTC medicine that only softens stool (without creating an urge to poo)?

What about dried sweet plums soaked in water?

You should be able to find them in bigger supermarkets or at shops like Kaldi. And they taste nice as well.

酸化マグネシウム, magnesium oxide.
if it works well, you should go to medical doctor. prescription is cheaper.

prunes definitely work for me but the effect isn't nearly as good as docusate. I tried a few weeks of prunes + lots of water and fiber and it reduced my time on the toilet by about half (2 hours a day instead of 4 hours a day).

However the effects of docusate were much more powerful in terms of stool softening.

@Ken
I would like to avoid magnesium because it is dangerous to take long-term, while docusate can be taken safely long-term.

Yes, dry prunes taste delicious and perform miracle. You ought to try!

Does umeboshi, dried or cooked, help your stomach the same way as prunes?

Have you ever used Metamucil, or Benefibre?. These are a soluble fibre that you make in to a drink, which expands and softens hard stools. You usually take a glass before retiring at night, which gives it time to pass through the system. It may take a glass or two through the following day for it to work through, if you have quite a problem.
Metamucil works on psyllium, and Benefibre uses wheat germ. Other brands are Miralax and Citrucel.
I'm sure at least one brand is available in Japan, as they are worldwide brands.
