In this day and age, celebrities have a lot of influence over our politics. Garthwaite and Moore estimated that Oprah Winfrey’s endorsement of Barack Obama in 2008 netted him an extra 1 million votes [1]. More recently, an Instagram post by Taylor Swift led over 160,000 Americans to register to vote prior to the 2018 midterm elections [2]. With the advent of social media, we have an ever increasing need to know celebrities’ opinions on the political issue of the day. Celebrities by and large have obliged — but with notable exceptions.
Shawn Mendes is a pop singer/songwriter from Canada who became famous several years ago. If you’re anything like me, you wake up every morning, thinking to yourself, “What is Shawn Mendes’ position on the Kuril Islands territorial dispute between Japan and Russia?” You try Googling the “Shawn Mendes Kuril Islands” — but alas, just like on every previous morning, you fail to find a public statement from Mendes on the issue. Indeed, as far as I can tell, Mendes has never publicly stated his position on the dispute.

Well, lucky you: I believe I may have found out Mendes’ opinion, cryptically hidden in his 2018 single “Lost in Japan” [3].
The chorus of “Lost in Japan” goes:
Do you got plans tonight?
I’m a couple hundred miles from Japan, and I
I was thinking I could fly to your hotel tonight
‘Cause I-I-I can’t get you off my mind
Can’t get you off my mind
Can’t get you off my mind (oh)
Despite the song’s name, Mendes is clearly not lost in Japan: he is a “couple hundred miles” from Japan. This raises the question: if not in Japan, where exactly is Shawn Mendes lost? Let’s find out.

Consider Figure 2: circles of radius 200 miles centered at various points in Japan. Not much land is a couple hundred miles from Japan, but there is some. Perhaps Mendes is in South Korea, perhaps the Russian far-east. South Korea seems much more plausible, since it’s substantially more populous than these parts of Russia; but we can’t be sure yet. Let’s take a closer look at the lyrics.
All it’d take is one flight
We’d be in the same time zone
[…]
Do you got plans tonight?
I’m a couple hundred miles from Japan, and I
I was thinking I could fly to your hotel tonight
‘Cause I-I-I can’t get you off my mind
[…]
I know it’s more than just a friendship
I can hear you thinking ’bout it, yeah
Do I gotta convince you?
That you shouldn’t fall asleep?
It’ll only be a couple hours
And I’m about to leave
Mendes is a couple hundred miles from Japan and wants to fly there tonight to see his “more than just a friend” (henceforth, “friend” for short). There are several useful pieces of information in the lyrics, the first of which is “We’d be in the same time zone.” This implies that Mendes is currently not in the same time zone as his friend. Let us look now at a map of time zones in eastern Asia.

Aha! As demonstrated by Figure 3, Mendes cannot be in South Korea, because South Korea and Japan are in the same time zone.
Instead, perhaps Mendes is in China, and that “couple hundred miles” is an innocent understatement. However, China is too far from Japan for this to be a real possibility. Indeed, about the shortest flight that one could take between China and Japan is from Shanghai to Fukuoka.

The distance between Shanghai and Fukuoka is 545 miles, a quantity which cannot plausibly be called a “couple hundred miles.”
Figure 5: Official definition of a “couple.” [4]
There is another possibility to consider: the Ryukyu Islands, an archipelago of islands belonging to Japan, stretch very far south, almost to Taiwan:

The most southwesterly of these islands is a small island called Ishigaki, which is approximately 200 miles from Taipei, Taiwan.

The lyrics say, “All it’d take is one flight.” Is there really a direct flight from Taipei to this tiny island? Indeed, there is — for part of the year. China Airlines flight 124 is a direct flight from Taipei to Ishigaki that flies between the months of April and October
Figure 8: the schedule of the last flight of China Airlines 124 in 2019. It is a daytime flight [5].
(You might object that perhaps Mendes charters flights and so is unconstrained by public flight schedules. However, this is not the case: see here [6].)
The second issue is that Shawn Mendes is allergic to mosquito bites [7].
Im allergic to mosquito bites .. It sucks
— Shawn Mendes (@ShawnMendes) May 26, 2014
The Asian tiger mosquito is a mosquito species native to eastern Asia, and Taipei is teeming with these mosquitoes practically year-round [8].

It is therefore unlikely that Mendes would find himself in Taipei to begin with. This leaves us with only one possibility: Mendes is flying in from the barren lands of the Russian far-east. Let’s take a closer look.

The land masses belonging to Russia that are within 200 miles of Japan include: part of the Sakhalin Island; small parts of the east coast of the Russian mainland; and the Kuril islands to the northeast1. It turns out that between all of these places, there is only one airport with direct flights to Japan: the Yuzhno-Sakhalinsk Airport, based in the town of Yuzhno-Sakhalinsk, the largest on Sakhalin Island (population 180,000).
Figure 11: flights from Yuzhno-Sakhalinsk, the only Russian city with short direct flights to Japan [9]
- The flight, which departs at 6:30pm, arrives at… 6:00pm, due to a time zone difference.2 In the song lyrics, Mendes asks his friend, “Do I gotta convince you? / That you shouldn’t fall asleep?” But 6pm is hardly late enough that his friend might be thinking about going to sleep.
- Mendes goes on to say, “It’ll only be a couple hours / And I’m about to leave.” The flight alone takes 90 minutes. Mendes would presumably need to take a taxi to the airport, pass through security and customs, and upon arriving in Sapporo, take a taxi to wherever his friend is staying — all in all, probably at least four hours.
(One very reasonable objection is that the flight schedule could very well have changed since Mendes wrote the song. However, as far as I can tell, this is not the case: I checked the Web Archive for archives of the Sapporo Airport’s arrivals page, and going back as far as 2016 it appears that all flights from Yuzhno-Sakhalinsk arrived in the afternoon or early evening.)
It seems that we’ve overlooked something. And indeed, I believe we have: there are two airports to the east-northeast of Sapporo, labeled with red dots in Figure 11. These flights are to Iturup Island (the more northeasterly one) and Kunashir Island, both of which belong to the Kuril Islands chain.
It is helpful at this point to go over some history. The Kuril Islands have been a point of contention between Japan and Russia for quite some time. In the 1855 Treaty of Shimoda, the two countries agreed that the four southernmost islands — including the aforementioned Iturup and Kunashir Islands — would belong to Japan, while the more northerly islands would belong to Russia.
However, after World War II, Russia occupied these four islands, much as the allies occupied Germany after World War II. Ever since then, Japan has seen this occupation as a violation of its sovereignty, and although the islands are now unambiguously under Russian administration, Japan maintains its claim [10].

It is plausible, however, that Shawn Mendes thinks of the four southernmost Kuril Islands as rightfully belonging to Japan. So when Mendes says he’s flying to Japan tonight, perhaps he is talking about these islands.
Indeed: on Sundays, Aurora Flight HZ4617 departs from Yuzhno-Sakhalinsk at 7:50pm and lands on Iturup Island (the more northerly of the two red dots in Exhibit 11) at 8:55pm.
Figure 13: Schedule of Aurora Flight HZ4617 from Yuzhno-Sakhalinsk to Iturup Island [11]
- Mendes would arrive at Iturup Airport at 8:50pm and probably wouldn’t make it to his friend’s hotel until well past 9pm. The lyrics “Do I gotta convince you? / That you shouldn’t fall asleep” make much more sense with this flight in mind.
- In addition to the flight time being 20 minutes shorter, this is a domestic flight (since the Kuril Islands are administered by Russia), so Mendes wouldn’t need to go through customs. This means that, while Mendes is optimistic in saying that “It’ll only be a couple hours,” it’s a much less egregious underestimate on his part.
(There is also a 7-8:30pm flight from Yuzhno-Sakhalinsk to Kunashir Island on Thursdays. This flight also fits the constraints of the song lyrics, albeit somewhat less closely.)
Now, you might be skeptical of a step or two in the above reasoning. Perhaps flight schedules have changed. Perhaps I overlooked something. However, I believe that I have found incontrovertible3 photographic evidence that Shawn Mendes did in fact visit Iturup Island:

***
The case is closed: beyond a reasonable doubt, we may conclude that Shawn Mendes was in Yuzhno-Sakhalinsk, looking to fly to Iturup Island to see his friend. Crucially, then, when Mendes sings, “I’m a couple hundred miles from Japan tonight,” he is referring to Iturup Island as “Japan,” thus taking a clear stand on the territorial dispute over the Kuril Islands.
Prior to pursuing this line of inquiry, the Kuril Islands dispute was one of few political issues on which I had no opinion. However, learning of Shawn Mendes’ bold stance — his subtle, cryptic, yet cutting reference to these islands as “Japan” — has clarified my thoughts on the issue. I am now firmly on Japan’s side in this dispute and believe it imperative that we stand up to Russia and its immoral 1945 land grab.
Do you got plans tonight? Because if not — and if you happen to be reading this in Yuzhno-Sakhalinsk on an evening — then you’re a couple hundred miles from Japan tonight.

The reason I believe this image to be authentic is that I have already demonstrated it to be likely that Shawn Mendes flew from Yuzhno-Sakhalinsk to Iturup; thus, we ought not be surprised to find a photograph of Mendes at Iturup Airport.↩
