Maybe it's different in Tokyo, but here in Osaka there are no lines that only support PASMO, so I can't really see the benefit of using this over SUICA. Still, gonna set it up to check it out.
tl;dr Without PASMO train lines in your area, this isn’t a suitable option for you to check out…
*unless* you hate the Japanese Suica app, which has a dismal convoluted UI. The PASMO app’s UI is far superior to work with, even if I’m doing screenshot translations.
Proper answer:
Since many companies include travel allowance within each employee’s contract, they usually require that employees buy cheaper monthly train passes instead (called “commuter” passes).
Commuter passes cannot be issued by JR’s Suica if the boarding & destination train stations are a competing private train-line’s station. Likewise, PASMO cannot be issued as commuter passes if the boarding & destination train stations are a JR-line station.
So employees are forced to use PASMO to get a cheaper fare, and can’t use Suica to do that in these situations.
Also, Suica doesn’t provide monthly commuter bus passes, whilst PASMO does.
So really the comparison only applies if you’re buying in bulk (monthly passes), otherwise both cards are equivalent.
*unless* you hate the Japanese Suica app, which has a dismal convoluted UI. The PASMO app’s UI is far superior to work with, even if I’m doing screenshot translations.
Not sure why I'd bother adding Pasmo though, considering - and unless I'm missing something - Suica covering any and all use cases supported by Pasmo (so Pasmo being a full 100% subset of Suica)
Neither Suica nor PASMO are a subset of each other, but please read my explanation above this quote for the info you’re missing 😉
