In episode two, a new day dawns in Tokyo and Kelly has had yet another night of disturbed sleep. This time it isn’t the jetlag that has been keeping her up, but the fact that she has been unwittingly drinking laxative tea. But Kelly is in the mood for laughing it off and throws herself into her next challenge – Manga Cosplay.

Manga (cartoon) magazines are huge in Japan. Japanese youngsters like nothing better than to dress up as their favourite character and show off to other lovers of fantasy. Of course, its something Kelly can’t resist.

With the help of a new Japanese friend Mai, Kelly has just 24 hours to pull something spectacular together. They hit the town and buy a manga doll for inspiration, on which Kelly will model her look. A purple wig, several metres of shiny fabric and a hilarious fitting session later, Kelly hits the stage before several hundred other similarly dressed hopefuls.

It’s a great morning out, until a Japanese photographer suggests she strikes a pose that is less than innocent and all her reservations about the role of women resurface. Dejected, Kelly gets out of her costume and heads home. She tries to cheer herself up by doing what any self respecting Japanese youngster would do after a bad day – go and lose herself in Tokyo’s spectacular games arcades, but it only worsens her mood.

It is said that modern Japan is a window to the future and Kelly’s next job is thoroughly 21st century – she will be working in an oxygen bar. Instead of having a couple of beers in a conventional bar, customers can plug into a pure oxygen tank, a setting that looks more like a sci fi movie. The experience is supposed to relax and revitalise and can even help to burn fat. Despite still struggling with the language, Kelly loves working at the oxygen bar and she even puts an oxygen unit on her Christmas wish list. Back home, Kelly continues her mission to learn the language, taking in vital phrases such as “vodka and cranberry, please� and soon she puts all of her new found knowledge into good effect, with a well earned night out.

Kelly and Yumi visit a Host club, a nightspot where hard working Japanese women go to be courted by young Japanese men, who have a strong line in shiny tuxedos and cheesy chat up lines. The men feed Kelly strawberries, pay her compliments and then take the courtship to the next level with a Japanese drinking game, Pit Pat Pong. The climax is a series of baffling, but hilarious impressions of Robert De Niro and Mr Bean. Kelly is won over and hits the surreal dance floor with her new male companions.

The next day Kelly returns to the traditional and spiritual side of her quest, when she leaves Tokyo and heads for the beautiful mountains to become a Buddhist Nun. Midway through a lengthy sermon on impermanence Kelly dissolves into a fit of giggles. She spends the rest of day out of uniform and applying herself to a series of Buddhist tasks.

Back in Tokyo, she takes part in a mass Buddhist and uniquely Japanese event – the Burning Doll festival where people of all ages queue to burn their treasured childhood dolls. It is said to release emotion, be symbolic of life’s transience and bring good luck. Kelly is strangely moved by the whole event and reflects on her mum’s battle with cancer. It seems as if Kelly is finally settling into the country she loves.
