Why Japanese capacitors are so popular?

Do they have access to better materials or what?

Actually they have better developing technology and better hand work.

Mostly because they are considered to be the best in the industry. Not necessarily better materials, but better production and quality. They're also more expensive, which is why they're mostly on the higher end units, or only partially on some units.

Japan was always very good at electronics and the parts.

They are the major innovators and are very precise.

And most of the major brands are from Japan like Panasonic

Yeah, give this a read.
Japan being ahead of the game in terms of formulas, Taiwan/China using incomplete versions of the formula which were unsafe in the long term.

The capacitor plague is over now, but it was a big problem ~10-15 years ago and people remember that.

 

Basically Taiwanese and Chinese companies copied Japanese recipes for a more modern type of capacitor, but they didn't get the full formula and soon those capacitors started failing all over the place.

 

The Japanese manufacturers may still have some tricks up their sleeves and more reliable QA/QC, but the difference is not nearly as big as it used to be.

Japanese industry is good at refining technology.

Good thing that liquid electrolytes are gone. Few leaked in my equalizer from home theater audio system and it dissolved the PCB under it.

Aluminium Polymers are still pretty temp sensitive, but a bit more durable and won't leak liquids when they die.
