The Otaniemi district in Espoo, Finland is the home of the main campus of the Aalto University (formerly independent Helsinki University of Technology) as well as several student dormitories.
While niemi means just a cape (as in "landmass extending into a body water", in this case the Baltic Sea), scholars are less certain what ota means, as usual the story is a mess and includes hundreds if not thousands of years and several languages. However, in typical Finnish custom, today the area contains several roads, streets and other features named with the "ota"-prefix, like Otakaari, the looping main street of the district.
Some jokers call the district "Onaniemi", implying that the stereotypically male and geeky students of, say, computer science might have trouble finding sexual partners and would instead end up masturbating more than the general populace. An unsourced but plausible claim is that for decades, of all the small kiosks in the nation-wide R-Kioski chain, the one in Otaniemi was the top-seller of porn mags, but also the first place to suddenly lose those sales when the internet became fast enough to transfer photos and the campus network was expanded to the dorm rooms.
Like probably everywhere in the world, also in Finland the students of technology gravitated towards science fiction and fantasy, American shows like Star Trek and Babylon 5 of course being popular. However, around mid 90s, when the rest of us still relied on what our three-ish TV channels decided to air and what a couple of companies decided to publish (and what a handful of magazines decided to write about), they had the means and skills to learn about and acquire all kind of works of entertainment unknown to the internet-deprived masses. So, while everyone knew the 90s Moomin series, some had seen a couple of Miyazaki films on the TV and random kids were exposed to the mess that it is Ginga: Nagareboshi Gin, quite unsurprisingly the tech students were among the pioneers of the Finnish anime and manga scene as a separate hobby.
Which is probably why even on the Google Maps, it says basically (Here be) otakus over this seemingly innocent-lookíng small driveway.
