Even though iPhone accounts for a large share of Japan's smartphone market, Android users still number in the tens of millions. Google Pay is a service that tokenizes cards stored in a Google account so consumers can pay with one click in Android apps and on the Chrome web, and in Japan, where the cashless ratio has reached around 40%, it helps raise online payment conversion by removing the card-entry step.

For merchants in Korea with a high share of revenue from Android app-based services or mobile web, pairing Google Pay with Apple Pay is an efficient setup that covers Japanese customers across both device ecosystems. It is especially effective in industries with frequent payments, such as games and subscription-based digital services.

When a consumer selects a card stored in their Google account on the Android app or Chrome checkout screen, the yen payment is authorized using the tokenized card details. Hecto Financial collects the resulting funds in JPY in Japan, converts the currency, and settles to the Korean merchant in USD, KRW, or JPY as chosen under the contract. Details such as button placement and supported browsers should be confirmed in the technical documentation before integrating.

Google Pay integration can be explored by a Korea-based corporate merchant through Hecto Financial without a separate local contract in Japan. The supported browser and app environments, the range of card networks, and the fees, settlement cycle, and currency options are finalized through consultation before contracting.

• Business registration country

  Confirm contract eligibility as a merchant registered in Korea

• Sales channels

  The integration approach differs depending on whether you are online-only or also include physical stores in Japan

• Product categories

  Confirm in advance whether your products fall under categories restricted by the Google Pay operator's merchant policy

• Local regulatory compliance

  Confirm compliance with Japan's payment and foreign-exchange regulations (see official sources below)

Payments made through Google Pay are authorized in yen against the linked card, and Hecto Financial collects these funds locally. Settlement to the Korean merchant then follows currency conversion into whichever of USD, KRW, or JPY is designated under the contract, with the settlement cycle and fee rate following the contract terms. Refunds are also processed as a cancellation back to the original payment method, governed jointly by the card network's and Hecto Financial's policies, so please check the deadline in advance.
