Sekairo Journal
Around the world, all of it.
How we drew the route, how we bought the tickets, what it all cost, and the days that didn't go to plan. A family of four circled the world in 54 days across two journeys, with six months back home in between — and we are writing all of it down, exactly as it happened. Sekairo is the round-the-world planner born from that journey.
