Apology and report regarding "Digital Catalog" communication failure

We would like to express our deepest gratitude for your continued patronage.

We would like to once again sincerely apologize for the inconvenience and concern caused to our users due to a communication failure that occurred on our "Digital Catalog" site from the night of Sunday, June 14th to around 4:21 p.m. on Monday, June 15th, making it impossible or difficult to view the site.

As a result of our investigation, we detected a large number of requests for a short period of time to the digital catalog domain and found that an automatic control function was activated to protect security. As it took time to recover, access was interrupted for a long time. There is no leakage of personal information due to this communication failure.
We would like to once again apologize to all our customers and ask for your continued patronage.
