Which countries does LINE Pay cover?
LINE Pay is recorded against Japan / Taiwan in the Asia-Pacific region, which is the market where its consumer reach is meaningful for merchants.

The Japan / Taiwan country hub lists every other alternative and local method tracked for that market alongside LINE Pay.
What does LINE Pay cost a merchant?
Pricing for LINE Pay is not a single published number: it moves with monthly volume, vertical, entity type and whether you connect through a direct acquirer or an aggregator. Effective pricing bands per provider, plus the fixed-fee and FX components that sit alongside the headline rate, are part of the founding-partner dataset rather than this public Japan / Taiwan profile.
Which PSPs and aggregators give access to LINE Pay?
Access to LINE Pay runs either through an acquirer with a direct rail connection or through an aggregator reselling a partner's connection, and the two differ in reliability and reporting.
