This year, Japanese society was affected by the novel coronavirus infection, and normal things cannot be done normally. The same goes for temples. Regular annual memorial services have been postponed or canceled. Even if it was an annual memorial service, I think there were cases where people were forced to refrain from doing memorial services, similar to refraining from going out.
If you search for sites that explain the sayings and events of Obon and Ohigan, I think there are quite a few. This does not necessarily apply to the customs of your area or events held at the family temple. I think there are also websites that explain local customs and Obon events. However, the details of the events are not necessarily the same depending on each temple. If you don't understand, I think it's important to ask the family temple.
Our temple is Obon in August, and we are sending out this year's Obon guide a few days in advance. However, in order to prevent infection, the details of the information have been slightly changed. I think Ah-tan also received a notification from the family temple. I think there were changes this year in particular depending on regional conditions and the timing of the event. It would be impossible for people from other regions to give accurate answers.
It is said that “notifications will come on the New Bon Festival and the equinox,” but I think there is a difference between the previous year's notifications and this year's notifications. I think there is no choice but to ask Bodaiji about this too.
It's the 23rd anniversary of my grandfather's death, and I think it was quite difficult to do it in April, the day of his death. There are cases where opinions are divided depending on the individual temple as to whether it is OK to go in conjunction with the first anniversary. (There is also a way of thinking that it is inappropriate to hold the 49th, 100ka-day, and 1st anniversary memorial services together with other annual memorial services.) I think it would be a good idea to talk to the family temple, saying, “I wasn't able to celebrate my 23rd anniversary in April, but I'd like to do a memorial service together for my father's first anniversary.”
