“Obon” is a very special Cultural Festival, as you well know. In England, we do not have any such ‘festival’ or ‘event’ commemorating our ‘ancestors’, it is up to the individual when to do this.
However, at various ‘Japan towns’ or ‘Japanese museums’ around the world, they do have such events.
When I lived in Florida, I was lucky to have the ‘Morikami Museum’ close by, so I would often go there for festivals or just to get away and have a bit of ‘peace’ and sit in the tranquil gardens.
