Zaifs

Zaif, sometimes written as Zaifs, is a Japanese cryptocurrency exchange established to provide online platforms for buying, selling, and trading digital assets. The service was operated by Zaif Co., Ltd., which was part of the Tech Bureau group, a company involved in various blockchain and crypto-related ventures. Zaif offered access to a range of cryptocurrencies and provided custody solutions for user funds, with trading activity focusing on cryptocurrency pairs and related services common to exchange platforms.

Historically, Zaif emerged as one of several domestic exchanges serving Japan’s growing crypto market. The platform aimed to offer user-friendly interfaces, security controls, and regulatory compliance expected of major operators in Japan’s evolving crypto landscape. During this period, Zaif competed alongside other domestic and international exchanges for liquidity, users, and listings.

In 2018, Zaif experienced a significant security incident described as a breach that resulted in losses of a portion of customer assets. The event prompted scrutiny from regulators, pauses or adjustments to certain services, and actions aimed at compensating affected users while strengthening security measures and governance. The incident had broader implications for trust in exchanges and contributed to ongoing discussions about security standards and regulatory oversight in the Japanese market.

Following the breach, the Zaif business underwent restructuring, with changes in management and ownership arrangements while continuing to operate under regulatory scrutiny. As with many exchanges in the region, Zaif’s status and operations have been influenced by evolving industry practices and Japanese financial regulations.
