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.

The Plum Blossoms of Kairakuen

Mito’s famous Plum Blossoms Festival dates back to more than 120 years ago. The main venue Kairakuen is one of the Three Great Gardens in Japan along with Korakuen of Okayama, and Kenrokuen of Kanazawa. During the Edo period, in July of 1842, the 9th lord of the Mito-clan opened Kairakuen as a public park for the local people to enjoy.

There are approximately 100 varieties of the plum tree growing in Kairakuen, and they all bloom at different times. Early blooming varieties (hayazaki) begin around mid-January to mid-February, mid-season blooming varieties (nakazaki) around early February to mid-March, and late blooming varieties (osozaki) around early March to early April. These times can vary every year though, depending on the climate.

Of the 3000 plum trees in Kairakuen, only around half of them can be said to be of a particular variety (the other half being mixes of a number of varieties resulting in an unnamed variety). The most common among those with clear names is the Shirakaga variety, of which there are nearly 450 trees. The next most common is the Tōjibai, with 150 trees, followed by Yaekankō, with 130 trees.


Although the trees bloom roughly as described above, they are greatly affected by weather and precipitation, so it is not an exact timeline. This is why you should visit Kairakuen several times to stroll around the park and appreciate the many forms of the plum blossoms.


Early Blooming Varieties (Mid-January to Mid-February)

The Yaekankō, Shironaniwa, Yaetōji, and Rekkōbai varieties are representative of the early blooming plum tree varieties and can be found scattered around Kairakuen. In particular, the Yaekankō in the East-West Plum Forest near the East Gate and the Shironaniwa by the Onari Gate are well known and among the first to bloom. Searching for the few flowers that have blossomed among the majority that are still in their bud forms is one of the most enjoyable things to do during the early blooming season.


Mid-season Blooming Varieties (Early February to Mid-March)

The single-petaled Tsukikage with its distinctive silhouette and the soft and fluffy Tora-no-o are exemplary of the mid-season blooming varieties. They can be found scattered around the park in the Western Plum Forest and other locations, and are known for their fragrance and colour. It is when the mid-season varieties are in bloom that you can fully feel the coming of spring and enjoy the grand sight of many plum trees in full bloom.


Late Blooming Varieties (Early March to Early April)

The Shirakaga, Kasugano, and Kōnanshomu varieties are representative of late-blooming plum trees. In particular, Shirakaga trees can be seen all around the park. They bloom slowly and decorate the end of the plum blossom season. The end of the season is when you should savour the last of the blossoms before they are gone.

About the Exhibition:
Japanese Swords, katana, have been getting more attention recently in popular culture. However, the terminology associated with the Japanese swords can be extremely confusing. When we examine a Japanese sword, what should we be looking at and how should we appreciate its beauty?
This exhibition seeks to explain the variety and evolution of the figure, surface, blade pattern and the exterior of Japanese katana through presenting the museum’s very own Japanese sword collection. Works of Ibaraki swordsmith and blacksmith are also presented in the exhibition. Through very simple explanation, the display introduces the beauty behind the history of the Japanese sword, and the ways to examine the swords. We invite all of you who are interested to learn more about Japanese katana to join us in this wonderful exhibition.

One Day in Ibaraki

From Iwase to Itako – Exploring Ibaraki on the Tsukuba Kasumigaura Ring Ring Road

View of Mt. Tsukuba

The Tsukuba Ring Ring Road is well-known cycling track in the west of Ibaraki. It was once the Tsukuba Railway, which was discontinued in 1987 and eventually turned into a scenic cycling track stretching 40km from Iwase Station to Tsuchiura Station. Recently it was extended to join the road around Lake Kasumigaura and form the 180km Tsukuba Kasumigaura Ring Ring Road. With the extension of the cycling course, the Ibaraki Prefectural Government has teamed up with seven municipalities around Lake Kasumigaura (Tsuchiura, Ishioka, Tsukuba, Itako, Kasumigaura, Sakuragawa, and Namegata) to set up a bicycle rental system allowing you to rent bikes from one of seven locations and return them to any of the other locations. We rented cross bikes and cycled one of the most popular sections of the course – the old railway track.

We set out from Iwase Station at around 10am. We were immediately given a preview of the scenery we would enjoy along the way – rolling fields, spring flowers, and distant mountains. Not long in we discovered an optional side trip of about 3km up to Amabiki Kanon Temple – unfortunately, we didn’t have time to go the whole way, but if you want an extra challenge (the roads are quite steep) and are keen to see one of the most scenic temples in Ibaraki, this is definitely an accomplishable sidetrack from the main path. The road is marked quite clearly with signs so with the help of a map you shouldn’t have much difficulty finding it.

FullSizeRender 21FullSizeRender 18


Our first stop was in the Makabe Rest Area. The Ring Ring Road is punctuated by six rest areas between Iwase and Tsuchiura that were once stations on the Tsukuba Railway. Now they have seats, bathrooms, and some have pumps for your bike tires. When we reached the Makabe Rest Area we departed from the road once again to cycle through the old streets of Makabe, a castle town that was planned in the Sengoku period and completed in the Edo period. 99 buildings around the town have been designated as National Registered Cultural Properties. The town is renowned for its Hinamatsuri doll displays in February and March. There is a café called Hashimoto Coffee where you can drop in for a cuppa – unfortunately, it is closed on Tuesdays, which is the day we visited.

As we continued along our path we drew closer and closer to Mt. Tsukuba. When we reached the Mt. Tsukuba Rest Area, we decided to veer off the track again in search of somewhere to eat and we found Maruchu, a soba restaurant. The food was delicious so I would definitely recommend it for lunch, but take care as the location of the store is not exactly where it says it is on google maps. If you head toward the google maps pin but turn left when you reach the street with a Lawson you will find it on the right side of the street.


After lunch, we powered along until we got to Tsuchiura. When we arrived in the city, we ventured off toward Lake Kasumigaura. Once you arrive at the lakeside you are treated to a beautiful view of the water. If you continue around the lake you have the option of visiting the Lake Kasumigaura Environmental Science Center, a museum and research centre on the northwestern side of the lake. Inside are a number of exhibits introducing the flora. fauna, and history around Lake Kasumigaura.

Finally, we headed back toward central Tsuchiura to return our bikes and have a well-earned ice cream before catching the train back to Mito. We explored just one section of the cycling path – there are many more recommended courses to check out. Whether you want a relaxed 10km course or a more intense 80km one (you could do the whole 180km if you’re up to it!), this well-serviced cycling course has something for everyone. Check out the information below and start planning your own adventure!

Spring is in full swing at Hitachi Seaside Park! Until April 21st, you can visit to see the tulips. Then, from April 22nd to May 14th, you can see the park’s famous nemophila flowers (also known as baby blue-eyes) covering 3.5 hectares on Miharashi Hill, creating an ethereal panorama of blue sky, blue sea, and blue flowers.

Nemophila are annuals that bloom from April to May. The nemophila used in Hitachi Seaside Park are of the Insignis Blue variety. Whilst they are in bloom until mid-May, after they blossom they begin to pale, so the best time to see them is during Golden Week.

Every year tens of thousands of people visit Hitachi Seaside Park to admire this rare sight. If there’s one thing you should see while you are in Ibaraki, it’s this!

In the two weeks of the festival approximately 6.5 million people attend and 6 million cups of beer are consumed, leading the festival to be known as the world’s largest food festival. Around 10 years ago celebrations of the festival began to pop up around Japan, and it has been gaining popularity ever since.

At Hitachi Oktoberfest 2017 you can enjoy delicious local foods and German beer in the oceanside city of Hitachi as local musicians and performers provide entertainment. In order to reduce waste and broken glasses, you will be charged a 1000 yen glass fee with your first glass of beer, which will be returned to you when you return your glass. You can continue to use the same glass for refills.

There will be no parking available, so you are encouraged to come to the event by public transport.
