Dear Valued Customer,

Starting July 2023, (billed August 2023), there will be a slight adjustment to monthly the fees.

The additional charges are as follows:

1. Universal Service Charge (ユニバーサルサービス料) : 2 yen (2.2 yen with tax) per month
2. Telephone Relay Service Charge (電話リレーサービス料): 1 yen (1.1 yen with tax) per month.

That is a change of about 3.3 yen to your bill per month.

Please be advised. Thank you.
