Sony-backed cryptocurrency exchange S.BLOX has listed Cardano and Midnight on its Japanese platform, marking the first time a privacy-focused blockchain's native token has appeared on a registered Japanese exchange. The listings went live on August 24.
Midnight's NIGHT token is the first asset from a privacy-chain ecosystem to clear Japan's regulatory framework for domestic exchanges. S.BLOX operates under Sony Group's ownership structure. Cardano founder Charles Hoskinson described the NIGHT listing as a major milestone for the Midnight ecosystem.
S.BLOX is licensed to operate in Japan and subject to the Financial Instruments and Exchange Act, which imposes custody, capital and disclosure requirements on exchanges. The addition of Cardano, already traded on multiple Japanese platforms, carries less regulatory novelty than Midnight's entry. Midnight is a privacy-focused Layer 1 blockchain launched in 2024 as an IOG incubator project. NIGHT itself is unshielded on-chain, though the token enables interactions with the network's privacy-preserving smart contracts.
Japan's domestic exchanges have historically avoided privacy tokens, citing Financial Action Task Force guidance on transaction monitoring. The Japan Virtual and Crypto Assets Exchange Association, an industry self-regulatory body, has no explicit ban on privacy-chain listings but members typically list only coins with transaction transparency. S.BLOX has listed NIGHT on a registered Japanese exchange.
Cardano ranks ninth by market capitalization at roughly $42 billion. Its adoption on Japanese exchanges has expanded in 2026 as institutional interest in Cardano staking and smart contracts grew. Midnight, by contrast, remains nascent and has not yet appeared on major global exchanges, making the S.BLOX listing its most prominent trading venue to date.
S.BLOX now carries both major Cardano and Midnight ecosystems at a Japanese exchange with Sony backing, a combination that no other domestic platform offers. If S.BLOX faces regulatory pushback on NIGHT, the broader question of whether Japanese regulators will permit privacy-chain tokens on registered exchanges will move from hypothesis to precedent.
