To all users of Binance Japan
Thank you for always using Binance Japan (hereinafter referred to as “our company”).
Currently, in relation to Bitcoin (BTC), we are planning a hard fork that will split off a new crypto asset “eCash (ECX)” from the Bitcoin blockchain.
As a result, we may temporarily suspend token deposits and withdrawals within the same network.
The new blockchain created by this hard fork is scheduled to be implemented when block height 963,648 (around August 23, 2026) is reached.
At our company, it is undecided whether we will handle eCash (ECX) and whether we will grant it to customers. We will make a decision based on our company’s policy guidelines for planned hard forks and newly issued crypto-assets and notify you again at a later time.
Important notes:
There will be no impact on the token’s functions themselves, and you can continue using it as before.
Binance Global will provide all the technical support necessary for users.
For deposits and withdrawals on the network mentioned above, we will resume operations once the network’s stability has been confirmed.
The information provided is as of the announcement date. Depending on future circumstances, the contents may be changed.
We apologize for any inconvenience and kindly ask for your understanding.
We sincerely appreciate your continued patronage.

Important notes:
Crypto-assets are not “legal tender” whose value is guaranteed by a country, such as Japanese yen or U.S. dollars. They are electronic data exchanged over the internet.
Crypto-assets can be used for the settlement of consideration only if the party receiving the consideration agrees.
Crypto-assets may result in losses due to price fluctuations. You may lose money, for example if the price of crypto-assets suddenly drops or becomes worthless overnight.
Due to changes in market conditions and liquidity, you may not be able to trade at the order price and quantity you placed.
The value of crypto-assets may be lost due to the failure of the blockchain or other record-keeping mechanisms, among other reasons.
The price of a crypto-asset differs between the purchase price and the selling price.
If you lose your private key or password, you may be unable to use the crypto-assets you hold and may lose their value. If others learn that information, there is a risk that the crypto-assets you hold may be transferred regardless of your intent.
We manage our customers’ assets separately from our own assets; however, if we become insolvent, we may not be able to return the deposited money and crypto-assets.
When conducting transactions, please ensure you fully understand the details of the transaction and proceed at your own responsibility.
