What is Coincheck Exchange?
Coincheck is a Japanese cryptocurrency exchange offering spot order book trading, an instant marketplace, automated recurring buys, and custodial staking. Owned by Monex Group, the platform held over ¥631 billion in customer assets across more than 2.62 million verified accounts as of June 2026.
Ownership and background
The company was founded in Tokyo in 2012 by Koichiro Wada and Yusuke Otsuka, who holds a master's degree in quantum mechanics from Waseda University and previously worked as a UX designer at Nexway. Coincheck launched its exchange service in August 2014 under the corporate name ResuPress, Inc. In April 2018, online brokerage Monex Group acquired Coincheck for ¥3.6 billion (around $33.4 million) following a security incident. The leadership team includes Executive Chairperson Oki Matsumoto, CEO Gary Simanson, incoming CEO Pascal St-Jean, and CFO Jason Sandberg.
Trading products and onboarding
Coincheck operates two primary retail trading venues: the central limit order book Exchange and the simplified Marketplace. Onboarding requires full identity verification, which Japanese residents can complete using their My Number card. Traders fund accounts via Japanese online banking or convenience store deposits. The order book supports limit and market execution without spread fees on primary pairs. The marketplace allows instant retail buys starting from ¥500 across major tokens, while the Coincheck Reserves service automates daily purchases from ¥300. Staking rewards accumulate automatically for supported assets by holding balances in the custodial wallet.
Trading fees and expenses
On the central order book, Bitcoin spot trading carries a 0% maker and 0% taker fee structure. Other pairs have specific schedules, such as Ethereum Classic at 0.05% maker and 0.10% taker fees. The instant Marketplace charges an embedded spread fee that ranges between 0.1% and 5%. Cryptocurrency network withdrawal fees vary by token, with Bitcoin withdrawals costing between 0.0005 BTC and 0.001 BTC.
Regulatory oversight and security history
In January 2018, an attacker stole approximately 500 million NEM tokens (worth around $530 million at the time) from an unprotected hot wallet that lacked multi-signature protection. The FSA issued business improvement orders, and Coincheck reimbursed affected customers in Japanese yen prior to completing its acquisition by Monex Group.
Risks and limitations
Coincheck acts as a centralized custodian, exposing account holders to counterparty risk and centralized wallet security dependencies. Its asset list is limited compared to global venues, focusing on around 17 listed cryptocurrencies. Trading on the instant marketplace incurs retail spread costs up to 5%.

Our review
3.4/5
Fair
Coincheck combines a Japan-focused exchange with simple recurring purchases, but its 2018 theft and marketplace spreads remain important trade-offs.
Coincheck is a Tokyo-based Japanese crypto exchange and wallet platform operated under Monex Group, which acquired it in April 2018 for ¥3.6 billion, about $33.4 million. The exchange launched in August 2014 under Coincheck, formerly ResuPress, and was co-founded by Koichiro Wada and Yusuke Otsuka. It reported 2,624,858 verified accounts in June 2026, alongside ¥631,633 million in customer assets.
The product covers spot buying through Coincheck Marketplace and order-book trading through Coincheck Exchange. Marketplace purchases start at ¥500, while Coincheck Reserves supports automated purchases from ¥300 per day. Coincheck lists Bitcoin, Ethereum, XRP, Solana, Stellar Lumens, Dogecoin and PEPE. The site shows BTC, ETH, XRP, SOL, XLM, DOGE, PEPE and other assets, while a recent listing added NOT A HOTEL COIN.
Fees depend on the product and asset. BTC order-book trading is listed at 0% maker and 0% taker with no spread fee. ETC is listed at 0.05% maker and 0.10% taker, while Marketplace fees range from 0.1% to 5%. BTC withdrawals have been listed at 0.0005 BTC and, in another published schedule, 0.001 BTC, so the applicable asset fee and route matter. Coincheck Exchange supports limit and market orders, chart analysis, a web interface and mobile apps. The service also offers staking and recurring purchases.
Monex Group owns Coincheck. The history still includes a serious weakness: in January 2018, an unprotected hot wallet without multisignature support lost about 500 million NEM tokens, worth around $530 million at the time. Coincheck reimbursed affected customers in Japanese yen and later changed ownership.
Its strengths are Japanese market access, recurring purchases, staking, and zero listed BTC order-book fees. The main weaknesses are the past custody failure, Marketplace charges of up to 5%, and restricted international availability. It suits Japan-focused spot buyers who want recurring purchases or staking.
