This looks like a pretty interesting show part travel, part romance and even though it's not translated I enjoyed this episode, then I found this site which does an episode synopsis in English .
Ainori is a reality program where seven young men and women travel the world riding a pink bus. The program is reminiscent of a travelogue; as of September 2007, the show has followed the bus across 79 countries as participants explore both famous tourist attractions and more off-the-beaten-path places. The participants are led across each country by a native who serves as tour guide, bus driver, and friend. Upon reaching the border with another country, the bus stops and participants head out to their next destination country to meet their new tour guide and get into their new bus.
The show's twist is that the participants are each young, single people whose goal is to find love with another participant and return to Japan as a couple. When a participant has decided they like someone else, they ask the driver for a ticket back to Japan. They then declare their love to the object of their affection, and ask that the two return to Japan together. After a night's consideration, the person who received the love declaration can either answer with a kiss, after which both participants leave the bus for Japan. Otherwise, the jilted participant is left to return to Japan alone. Besides the love declaration, participants are forbidden from talking openly about their love interests with other participants, but inform the TV audience of their feelings through diaries and confessions to the camera (shot when no other participants are present).
After people leave the bus, new people are added to the program, to keep the total at 7 members. They are seen on the side of the road with a painted cardboard sign (appearing to be hitchhikers) and brought aboard after a self-introduction.
