International Olympiad in Informatics (IOI 2018)


On September 7th, we visited the Tsukuba International Convention Center where the 30th International Olympiad in Informatics (IOI 2018) was held.

The event is an annual international informatics competition where contestants from various countries come together and solve an array of computer science related problems and compete for a chance at a gold medal.


The number of participants in this prestigious competition has been steadily increasing. This year’s IOI welcomed more than 900 participants representing 85 different countries. While the event is mostly focused on science, it also gives participants to enjoy multiple different cultures through their interactions with the other contestants and the staff.

According to the volunteer we talked to, most of the volunteers were exchange students from Tsukuba University, the rest is made of Japanese students and staff of companies around the area. Each of them was assigned to a team in respect to their mother language or a language they are skilled at. And the volunteer is in charge of showing their assigned team to the dormitory, food court, contest halls, as well as helping them get around in the city while providing interpretation. Of the couple volunteers we talked to, all of them were enthusiastic to share their experience with the foreign teams.


“Showing the contestant teams around in Tsukuba city was really fun, it reminded me of my first culture shock after coming to Japan a few years ago. I made some great friends through this opportunity and we have made promises to meet again either in Japan or somewhere else in the world.”

“I felt very connected to be able to meet someone from my home country who lives in this city,” says one of the team member in regard to his assigned volunteer exchange student, “It gave me a sense of home while competing in a country I have never been to, and I was able to learn so much about the life here, makes me want to come back again in the future.”


We had the opportunity to interview some of the contestants and staff to get their perspectives on the event and what brought them all the way here to Japan.

The Japanese national team was made of some of the most intelligent students one can ever meet, they are a little shy to speak at first, but when the topic is brought upon the contest itself, their eyes were filled with joy and excitement. They complimented each other on their respective results in different sessions and expressed how amazed they were by the talent of other foreign teams.


“You never know how big the world, and how many greater people are out there until you really compete with them.” says the Japanese contestant Inoue Wataru, “I see them, just like regular students, and I didn’t expect how amazing they are when sitting in front of the screen.” Inoue Wataru won personal score of 6th place in the entire contest, we must say he is being overly humble with his words, as we felt the exact same about him and his teammates.

The Chinese contestants were no doubt the best in their team effort, all of the four members won the gold medal with personal results of 2nd, 3rd, 6th and 23rd place. Unlike the other teams who dressed very casually, they came to the event in matching suits and ties. However, when confronted about this, they laughed and replied with a blush. “Our coach teacher said that we should wear suits because Japan values those who dress formally to international events such as this one, so we thought we should follow the culture here. But turns out we are the most formally dressed, teams from the other countries just wore shorts and t-shirts like they would if they work in silicon valley.”

They explained to us the very strict selection process of contestants from China, the 4 of them were chosen through 3 stages of intensive selection tests and training camp, out of over 2000 students who signed up from schools all over China.

DSC_9403Finally, we were able to talk to the legend himself Benjamin Qi. Before attending the event, we had no idea who he was but once we arrived at the venue, he was all everyone talked about. “Have you met Benjamin Qi?!”, “We call him BenQ”, “His talent is out of this world”.

When we met Benjamin, he came out of an elevator and suddenly all the contestants had their heads turned towards him. “Oh, he’s here! He’s here! That’s BenQ!” That’s when we knew we had to make find out why this particular competitor was so famous.


As far as the first impression goes, Benjamin seemed like just any other regular high school student. One could not have imagined that he was one of the leading programmers of his age group. When asked about his fame at the event he was very humble about it and said he wasn’t a fan of all the attention. Benjamin Qi is a high school student from Princeton, the United States who made a name for himself at this event by achieving a perfect score on a problem that lasted for 5 hours. A feat no one has to come to achieve up until this year’s Olympiad. Benjamin gained interest in computer science while in 8th grade.

DSC_9411He said he self-studied until he entered high school where he took classes on the subject. To secure a spot at this year’s IOI 2018, Benjamin participated in a 6-day long competition in North Carolina where he and other high schoolers went head-to-head to become one of the United States’ representatives at the event. As the for the event, Benjamin noted that it was a fantastic opportunity to put his skills to the test as well as great exposure to a variety of global cultures. Benjamin won 2018 IOI personal best with 4 perfect scores and a big percentage gap with the 2nd place winner.

In the end, we realized that we were only merely taking a slight peek under the curtains, the world of informatics and how important these skills are to the future society is unable to be valued.


We live in a world where words such as “geeks” and “nerds” are still widely used as insults and mocking to people who have different interests than the so-called “majority”. It is sad to see students being bullied at school and called names because their talents are not being understood by the ignorant mass. However, the nerd discrimination is bound to disappear as leading figures like Steve Jobs and Elon Musk who are bringing significant changes to the world through technology. We hope that one day, the contestants will shine on the world stage with their great talent in informatics and the skills to push our society forward.



This is the first time the IOI is hosted in Japan, and Tsukuba city was selected to be its hosting venue. The city of Tsukuba is also known as the Tsukuba Science City, it is now the most significant science technology accumulation site in the country, where more than 300 public and private institutions and enterprises are located. Many foreign researchers and exchange students who seek for high-level experiences and opportunities gather in Tsukuba. The city also offers various services in multi-language to support the living of foreign residents. While its foreign residents give back to the community by doing volunteer works, representing Tsukuba and acting as the bridge between this city they live in and the world.
