Domestic crypto-asset merchant payment + Lightning Network

Wiki route

This entry sits under exchanges index. Read it against FSA crypto-asset exchange registration system — number system / Local Finance Bureau jurisdiction / registration requirements for peer / contrast context and Japan Financial Regulation — Legal Framework for Tokens, Crypto Assets, and Payments for the broader system / regulatory boundary.

Overview

Domestic crypto-asset merchant payment was introduced via bitFlyer / Coincheck during the 2017 BTC bubble, but contracted due to the 2018 outflow incident + price volatility. From 2023onward there have been signs of revival with the spread of the Lightning Network, operated mainly by tourist-area and Web3 -native businesses.

Major domestic operators / services

• bitFlyer payment service: a BTC payment platform for merchants, launched 2014 , partially scaled back
• Coincheck Payment: BTC/ETH and other payment for merchants, launched 2014 , scaled back after the NEM incident → resumed
• GMO Coin payment (GMO Internet G group): GMO Payment Gateway linkage, partially trialed
• Pay-bitcoin and other independents: for small and mid-sized stores
• Domestic BTM (Bitcoin ATM): Gaia Co., Ltd. — Japan crypto-asset exchange operator overview 2022-08 first domestic operation, 2026-05 temporarily suspended

Lightning Network domestic adoption

• Lightning Labs (LND) / Blockstream (Core Lightning) / ACINQ (Eclair) — Lightning node implementations
• BTCPay Server: open-source merchant gateway, adopted by some domestic operators
• Strike (Jack Mallers): USD/BTC international remittance, no full-scale domestic entry
• Crypto Garage SETTLENET PRO: Lightning + Blockstream Liquid sidechain for institutions

Regulatory position

• Lightning node operation: under the amended Payment Services Act, possibly falling under fund-settlement operator (remittance operator); the FSA has not published an explicit view as of the 2024 stage
• Merchant payment: for merchants, depends on the payment-agent operator (prepaid payment instrument / funds-transfer business) license — jp-vasp-aml-travel-rule-implementation
• Taxation: merchant receipts are business income; individual payments are miscellaneous income

International comparison

El Salvador (BTC legal-tender adoption 2021) · US Cash App (Strike linkage) · Argentina retail (em-market-crypto-dollarization-pattern) · domestically, adoption is delayed by regulatory caution + price volatility. Stablecoin linkage (jp-cex-deposit-token-stablecoin-integration) is a candidate for the next-generation payment layer.
