Is it possible to change the status of a Supporting Member midstream?

It is possible. You can upgrade your membership status by paying the difference.
In such cases, the expiration date (termination date) of the membership status will not change. Please note that downgrades, such as changing from Gold to Silver membership, cannot be handled.

If I am a general member, is it possible to change to an annual lump-sum payment?

Due to system reasons, credit card payment is only available for monthly payment.
If you are a general member and wish to make a one-time annual payment, please check the URL below and submit your application via Google Form.
