A mirror site of this website has been set up below:
The reason is because the akenotsuki.com domain might be discontinued in order to reduce my expenses. Right now it is just a possibility, and nothing has been decided.
The akenotsuki.com domain is due for renewal in early October, but the hosting server needs to be renewed in September. Therefore, if this main site were to disappear, it would most likely be shortly after October begins or in mid-October.
Conversely, in years when the site remains accessible in late October, it will remain available until at least September of the following year.
I intend to make another formal announcement if I have no choice but to officially abandon the domain, but I wanted to announce in advance as there may not be enough time to notify.
