A lot of it comes from a “no man left behind” mentality. They won’t stop using something if there is still somebody using it. Took them forever to stop good old pager services. On the one hand you have pretty advanced payment methods, super high tech toilets. On the other hand they still use faxes a lot. I worked in a business where global asked us to join their digital marketing campaign to attract customers to events. We had to tell them “sorry, unless you fax the info, you won’t get much traction here” and we were not kidding.

Lastly, Japan is/was great with hardware but they are incredibly bad at software. Their website design is - by European or North American standards - incredibly bad.
