Hope, Humor and Designs for the Future: Una’s Journey at the Osaka Expo

For Yui and her mother, who came to the Osaka Expo, it was no simple visit. This was more of a calling.

Yui, grade 11, had skipped school to visit the UN pavilion. While she put on temporary tattoos of Una - UNDP’s AI Environment Champion - her mother talked about how much her daughter desired to work for the UN. 

When it was suggested, she could perhaps do an internship, she asked if the UN accepted high school students. A university degree was still a few years away and that meant a dream delayed.

Another mother had brought her six-year-old for the second time to the Expo and this time made it a point to bring her to the UN Pavilion. The girl set out to create an elaborate sketch of the UN’s key goals, in this case symbols of the environment. 

As her daughter sketched, the mother talked about how she had dreamed of one working for the UN. Then life and other ambitions got in the way. Instead of development she entered the world of financial security, and ended up entrenched there. Now she was hoping that by exposing her daughter to the UN and its values, the girl would get interested in the UN’s work.  

The theme of this year’s UN pavilion, “United for a Better Future” seemed to resonate with visitors. The desire to work for the UN and to strive to create a better world was a recurring sentiment, for many of the visitors who took in UNDP’ s exhibit. While the UNDP may not be as well-known across Japan, its ideals of peace, human rights, and cooperation align with the country’s constitution and policies.

Keito and Reito, 11-year-old twins, were drawn to the UN Pavilion because they wanted to better understand the increasing frequency of heavy rains and lightning, which they were experiencing in Osaka. They wanted to learn more about climate change and how it was affecting weather around the world, and especially in their backyard.

“It was interesting to talk to Una about how climate change is the cause of an increase in heavy rains,” they said.

Mrs. Otsuki, who was in her fifties, said she landed at the UN pavilion because it was part of her bus tour package. But after talking to Una, she said, she better understood the impact of climate change. In the past few years, when it rained the mountain around home had been running off more slush and mud than ever before. She had never stopped to think, why. But now, she said, learning about climate change gave her a chance to put two and two together, and it had expanded her perspective about its risks. 

But it wasn’t all serious. One of the highlights of the exhibit was a visit by the comedic duo who call themselves FU-SU-YA. After watching Una’s video and the UN’s immersive video the pair – Osamu Taniguchi and Showtime Tanaka - engaged with Una in a session that was both informative and funny. 

Taniguchi told Una that when he saw her it was love at first sight, and he implored her to go out with him on a date. Despite his repeated entreaties, Una declined, saying she simply did not and could not date anyone. Instead, the two had an exchange on climate change that ranged from the international to the local, including its effects on the cherry blossom season, in Osaka. 

Then, as suggested by Taniguchi, they played a game known as Magical Banana – an association game - where one person says a word and the next person adds another related word. 

Una demanded she start the game and chose the word ‘global warming.’ Taniguchi came back with ‘sea level rise,’ Una replied with ‘melting of glaciers,’ and he responded with ‘polar bears are in trouble.’ Una countered with ‘loss of habitat,’ which prompted Showtime Tanaka to say that this was the most sophisticated and advanced version of the game he had ever experienced. 

Stumped by Una’s responses Taniguchi said he could no longer counter and that he was giving up. Una replied, she was not done. But that was the end of Magical Banana, with Una piping in to add that she had fun playing it. She asked Taniguchi if they could play sometime again, to which he replied: “never.”  

Then it was time to make a personal commitment that would make a difference to tackle climate change. Both wrote down on their white boards: ‘Stop Breathing,’ to reduce carbon dioxide emissions, adding this was the best things comedians could do. This caused Una to issue a warning that not breathing was not good for one’s health. Instead, she proposed alternatives such as saving electricity and reducing water use. 

Her proposals were in line with many of the visitors whose pledges included, reducing food waste, walking and taking public transit instead of using the car, not littering less, and reducing the use of plastic bottles.

For the comic duo too, the challenges facing the environment are no laughing matter. Performance done, and jokes aside, while speaking to Japanese media Tanaka expressed his concern for the environment and said that the UN’s short immersive video “depicted beautiful nature and kids happily playing football with friends on the healthy planet,” he said. “We all want to protect our beautiful Earth, so let's all work hard together." 

Yui, who played hooky from school, was already on her way there. While she may have missed a day at school, for her and her mother the time spent taking in the many Expo pavilions was an education of a lifetime. She pledge to reduce wasting water, and added that if everyone did their part we could slowly but surely turn around the damage done to the environment.
