I had the privilege of acting as one of 6 leaders for a group of 25 Venture Scouts (23 young gentlemen and 12 young ladies) to Japan on a similar trip. It was the summer of 2004 and we took a tour of Toyko, spent a weekend with some Japanese families, spent 6 days and nights at Japan's 6th Venture Jamboree, and spent 3 days and nights at a hotel in Narita at the Asia-Pacific Youth Forum with a Japanese contingent and a contingent from all over the area, including Scouts and Scouters from Nepal, Bhutan, French Polynesia, India, Pakistan, Hong Kong, Singapore, Bangladesh, Australia, New Zealand, etc., etc. Great fun. Great kids. What a privelege.
I'm certain you had an incredible time, and that your Venture Scouts came away with a better undertanding of Scouting as a Movement.
