Regular meetings will not be held on Sunday due to General Conference. Please see below for the official announcement letter from the Stake:

Dear Tokyo South Stake Members,

We are all looking forward to hearing the voices of the Lord’s servants in General Conference in October. General Conference will take place on September 30 and October 1st in Salt Lake City. However, due to the time difference, our Stake will have an adjusted schedule:

Sunday October 1st: Members should view the three Saturday Sessions of General Conference. No ward / branch meetings should be scheduled. Members may watch at their homes, but Bishops / Branch Presidents may open the church buildings for the broadcast of General Conference.
Sunday October 8th: Fast Sunday is observed. Wards and Branches hold Fast and Testimony meeting. Other unit and stake meetings should take place as usual.

Because of the time difference, Sunday Sessions of General Conference will not be broadcast until Monday October 2nd in Japan. As such, we encourage each family in the ward to find time to watch the Sunday Sessions sometime during the week.

Previously, we had sent instructions to the Stake Council and Ward Council that General Conference would be observed on October 7th and 8th in our Stake. However, we received instructions from the Asia North Area Presidency stating that the Area would participate in General Conference on October 1st. We apologize for the confusion and any inconvenience this may have caused.

We look forward to hearing the voices of the Lord’s servants at the next conference.
