Odeuropa @ World Expo2025 in Osaka

Odeuropa goes Asia! In the last week of April, 2025, three members of the Odeuropa team (Raphael Troncy, Cecilia Bembibre, and Inger Leemans), travelled to Japan to present the project on the World Expo in Osaka. We were very honoured by the selection of Odeuropa to be featured in the European Union pavilion. We were excited (and a bit scared) to meet the AI-powered ‘Odeuropa avatar’ (especially me, since my image and voice were being used for the avatar). And we made use of the opportunity to visit some Japanese smellmarks and other landmarks for olfactory culture in Tokyo and Kyoto.

Presenting Heritage Scents at the Expo

The expo, constructed on an island in Osaka, was at the last stop of the train. And even though it was early in the morning, the trains were completely packed, and the station swarming with people, who really started to run towards the pavilions as soon as the expo opened.

The European pavilion is themed Nurturing Tomorrow, showcasing initiatives that bring to life sustainability, connectivity, inclusivity, and security. Every day it received over 5000 visitors. We only were there for two days, but we feel we truly changed the pavilion into a heritage smellscape.

We gave four nose-on lectures, both for visitors and for invited parties, such as cosmetics and fragrance companies, and academic researchers. We also conducted a smellwalk around the expo. Amongst the heritage scents, generously supported by IFF, we distributed: frankincense, myrrh, pomander, gloves, Amsterdam canal, and (not to everyone’s liking and to the greater good of EU’s smellscape): the smell of hell. Cecilia Bembibre presented Cistus Labdanum in front of the Spanish pavilion, to commemorate this valued, but also threatened heritage scent from Andalusia.

As the expo turned out to be far too crowded for smellwalks, we decided to organize “show, tell and smell” sessions in the EU pavilion. This turned out to be a great success and many visitors lined up to smell with us. This way we could also get more easily into conversation with visitors about Japanese smell culture. When asked about significant scents and smellscapes, people talked about parks, blossoms, seashores, incense burning rituals, and also about the smell of tatami: Japanese floor mats which come close to the nose in the evening when people lay their heads to rest close to the floor.

The Odeuropa team was enriched with the presence of Yiwei Chen, of the South China Agricultural University, an expert in Chinese incense rituals and the smellscapes of Chinese traditional gardens. Yiwei presented a collection of scents she created for the famous Chinese novel A Dream of Red Mansions.

A special thanks to our translators! They truly invested in studying European smell culture and Japanese /English scent vocabularies – a steep learning curve.

Facing the Avatar…

To highlight three European research projects, the EU invited the German company Goava to develop three avatars of the PIs of the research projects, to be staged at large screens in the pavilion. The avatars are trained by AI to present the projects and answer questions in English and Japanese. The Odeuropa avatar also presents four heritage scents, which people can smell through colored scent cubes. It is quite confronting to see people interact with a live version of ‘yourself’, which speaks a language you do not master (Japanese), and speaks English with a perfect accent (whereas my Dutch-English is quite coarse).

Also, ‘my’ avatar has little sense of humor, even when ‘she’ says hilarious things such as – in response to question “How do you feel?”: “I’m feeling fantastic, thanks for asking! I am an avatar. I don’t get tired or bored, so I’m always ready to explore the world of historical smells!”. It was also truly funny to see people react to the fact that the ‘real’ version all of a sudden was standing next to the avatar – a great photo opportunity. After the expo, the avatar will be stored online, so it can keep on providing answers about Odeuropa project. This might come in handy with the press questions that still come in 🙂

On the hunt for smellmarks

Our trip to Japan also provided a unique opportunity to visit some of the ‘100 most significant cultural smellmarks of Japan‘ and other olfactory landmarks. We went smellwalking through parks, gardens, along incense-fumed shrines, and participated in tea ceremonies.

We were honoured to be invited for a tour through the fragrance heaven Kunjyukan – a splendid place where visitors can learn about and engage with the traditions of Japanese incense. We got a sniff behind the scenes of traditional incense making of Shoyeido, and ‘listened to scents’ with the president of the company, Mr. Masataka Hata, who also schooled us in the history of Japanese incense making and rituals (if you do not have the chance to visit the company: order Mr. Hata’s beautiful and insightful Koh Senshu: A Cultural History of Japan as Seen Through Incense). For the first time in our lives, we smelled Kyara – an extremely rare and precious agarwood.

In Tokyo, we visited the Green Terrace of the Aroma Environment Association of Japan (AEAJ). This Aroma Lab is a true heritage scent library, where we could sniff through a whole catalogue of essential oils, all well documented. Hinoki, Hiba, Plai, Kuromoji Linear…our smell diaries were filled with exciting new experiences for our noses.

And that concluded our sensory overloaded, but too short, journey through Japan. We learned a lot about Japanese smell heritage – knowledge which we take back home now. We are also looking forward to bank upon the new contacts we made for future research collaborations!

Update – Follow Your Nose!

During the project’s first 1.5 years, Odeuropa collaborated with Museum Ulm on a guided smell tour where visitors could discover the museum’s art collection through their nose. The tour, Follow Your Nose: a Guided Tour with Smells, officially launched in April 2022 and continues to run. The Odeuropa project developed the smells in collaboration with Museum Ulm and the fragrance company IFF. By creating historically informed smell interpretations, all collaborators aimed to turn a museum visit into a multisensory experience, opening new opportunities to enjoy, learn and engage with the collection.

Below, we provide an update on the event’s progress and accomplishments. Additionally, we outline a few key outcomes from this event’s development.

Progress Update:

Follow Your Nose! had a tremendous local impact. Throughout its first year, Museum Ulm conducted a total of 64 guided tours with 1.022 participants. It was a popular activity for local school classes – 366 of those participants were children visiting the museum. The museum successfully trained their staff and tour guides to use three different olfactory distribution methods proposed by Odeuropa and they experimented with olfactory storytelling through eight artworks and eleven specially designed smells. On conducting the tours, Museum Ulm’s curator Dr. Eva Leistenschneider reflected, “doing these tours is really fun – the tours are always full of laughter and animated discussions.” The successful collaboration and positive visitor response highlighted the potential olfactory methods can have on GLAM (galleries, libraries, archives, museums) initiatives and the benefits of identifying and overcoming the challenges which come with olfactory storytelling. 

The guided tour also had an international impact with many press outlets within Europe and the United States interested in the concept and development of the smell tours. To name a few, Follow Your Nose! was highlighted via radio on Inside Europe, via podcast on the American Historical Review’s History in Focus, via television on the BBC Travel Show and via print on the Augsburger Allgemeine

Museum Ulm will close in April 2023 for renovations until 2025, however, they plan to integrate all the artworks which are part of the Follow Your Nose! tour into their temporary collection at Kunsthalle Weishaupt and resume regular smell guided tour visits in Winter 2023. Both Odeuropa and Museum Ulm are extremely excited about the event’s success. Although it is clear that there is still much to be learned and researched within the field of olfactory storytelling and museology, successful collaborations like these exemplify the incredible possibilities and opportunities which lie ahead for this ever growing field. Dr. Leistenschneider said of the overall collaboration between Museum Ulm, Odeuropa, and IFF, “[we] appreciate the huge success that these tours [have] with our public. We are really happy to have had the opportunity to work with you all on the concept and discover the wonderful world of scent in GLAMs! Thank you all for this experience, it has been a pleasure!”

Key Takeaways of Olfactory Event Design:

These tours, as well as the other Odeuropa olfactory events, are used as examples which help research how to improve the pathways for olfactory interpretation, event design, visitor experiences, and conservation. With the successful collaboration and development of this olfactory event with Museum Ulm, the Odeuropa team is able to further shape its knowledge in guided tour design, storytelling, and smell development. This process supports and informs one of Odeuropa’s main goals which is to map out best practices and challenges of bringing smell to GLAMs. Olfactory events like these also provide Odeuropa the opportunity to collect questionnaire data from visitors which provide concrete evidence of what value visitors place on such sense-ational GLAM experiences. All these findings will be organised into an easy, open-access resource for GLAM professionals called the Olfactory Storytelling Toolkit, to be launched at the end of 2023. 

Using Olfactory storytelling techniques in GLAMs come with many challenges. At the beginning of the Odeuropa project, a workshop was organised together with Mediamatic, Working with scent in GLAMs – Best Practices and Challenges, which brought together a group of olfactory experts to early assess the challenges that this industry faces. Building on these findings, Odeuropa continued researching the best practices of olfactory storytelling in GLAMs with an aim to find solutions to the challenges. Particular findings from the Follow Your Nose! olfactory guided tour are explained below.

Flexible Olfactory Design

With this event, it became clear that flexible forms of olfactory design were necessary. Tour guides were trained to work with three different methods: Hand fans sprayed with scent to be wafted at larger groups (also met Covid-19 social-distancing rules), Whispis, which are a small device that puts out dry scented air, and blotters, which are a stiff paper that can be dipped in scent. It was important to Museum Ulm that the tour guides had options that suited different group sizes and age groups. After six months, the tour guides reported that all methods were effective and utilised in different situations. The ability to pick and choose these methods based on group size and the tour guide themselves was very important.

Smell management 

A challenge that both Odeuropa and Museum Ulm did not foresee was the issue of smell management, or the process of preparing and storing smells on location. Museum Ulm advised that each distribution method required different management and storage. For example, with some distribution methods the chosen storage place was emitting odour meaning that it could bother someone’s working space. This could not be prevented even when placing the Whispis in airtight containers. Storage was not the only challenge. Museum Ulm reported that when an olfactory tour was conducted in the museum (no matter which distribution method) a smell trail lingered through parts of the museum after the tour. Concrete solutions to these challenges are still being researched.

Do not fear the malodour
One of the barriers of olfactory storytelling is using malodours or unpleasant smells. Past research has stipulated that malodours pose a higher risk to visitors because they can cause negative emotional responses and are more difficult to distribute. Through this event, we learned that malodours can help heritage institutes provide new perspectives to their collections, narrating new, unexpected, and seminal stories about Europe’s culture and history. To our surprise, most visitors to our olfactory tours had quite positive reactions to the malodours, and they were interested to engage with more. Leistenschneider said of her own engagement with visitors and malodours, “in all the tours I conducted myself, I had only one participant telling me (after the tour) that they had preferred a tour without malodours. Everybody else was unanimous that a mixture of pleasant and foul scents made the tour more entertaining and interesting.” As is advised with any olfactory project, Museum Ulm conducted numerous test tours with various audiences before the launch to anticipate the impact of different smells in such situations.
