We found out the problems occurring at Japan especially of the Credit card transaction in online shop such like BASE(https://thebase.in/) and STORES(https://stores.jp/)
immediately We asked the question Why this things happen without any notice to the system support of those company.
And we had an answer from the credit card transaction system company here today.

According to the System supports from transaction system in those systems;

If it's usual, you can use it.
However, For now they are having credit card fraud ( such as third party use ) is rapidly increasing due to cards issued overseas.
They are performing the correspondence to temporarily raise the security level .
because of that Credit cards issued overseas is not available .
Therefore you can't use a credit card of certain overseas issue for a site.
They think whether misuse becomes available gradually if I dwindle.
To depend on external environment, it isn't possible to tell about clear restored hope.

So we decided to extend the Sales due to that idiosyncratic system problems.

And also we are developing the another online shop which transaction will be Paypal system that won't have such a problems.

so please be patient till it get fixed
