For almost two weeks, Jack and Liam, along with their caregivers and "Camp Mum", Tania McKenzie, got the chance to visit Christchurch's Sister City, Kurashiki, on a youth and disability exchange.
The trip offers the chance to visit a foreign country and explore a new culture, something that can be difficult to accomplish for families with disabled kids.
While promoting friendship between the two cities, the exchange also gives our Japanese counterparts a glimpse into Jack and Liam's lives.
