Aaron Crest Care Home, on Tanhouse Road, hosted members of the Skelmersdale Veterans Association (SVA) as part of the event.
They spoke with residents and shared memorabilia including gasmasks, uniforms, helmets, aircraft models and more.
The group reminisced about growing up during and after the war, talking about the impact it had on family life.
Resident Stanley Joel, a veteran of the Merchant Navy, rose to his feet and saluted when he saw the SVA members in uniform.
He said: “I was so happy to talk to them about my memories.”
Adrienne Ratcliffe, home manager at Aaron Crest Care Home, said: “We wanted to commemorate VJ Day as many of our residents have memories from that time.
“It marked the end of a long and gruelling war but families continued to struggle for a long time afterwards, rebuilding their lives in the aftermath.
“The day was a huge success, with everyone asking about the items the SVA brought, sparking reminiscences from their younger days.
“The SVA have agreed to come back and bring along other items our residents asked about, so we’re already looking forward to seeing them again.”
