Hottest Day in Tokyo August Heatwave in Japan
Hottest Day in Tokyo August Heatwave in Japan
Overview
In this intense live stream from August 2020, John Daub braves one of Tokyo's hottest days on record to demonstrate the reality of the Japanese summer heatwave. Standing in front of the iconic steam locomotive at Shinbashi Station, John measures ambient temperatures soaring over 38°C (100°F) and surface temperatures exceeding 50°C (122°F). He uses the opportunity to discuss the potential health risks of holding the Tokyo Olympics during this season, urging the committee to consider postponing to autumn.
Beyond the weather report, John engages with his live audience through experiments, such as melting ice cubes on the hot pavement to visualize the heat. He takes viewers on a short walk to a nearby 7-Eleven and vending machines to procure cooling drinks like Pocari Sweat and Mugi cha. The stream also covers personal updates, including a Kickstarter campaign for an Only in Japan Fireworks Festival in Akita Prefecture, replacing canceled local events due to the pandemic.
The video captures the unique atmosphere of Tokyo during Obon season, where business districts like Shinbashi are unusually quiet. John shares historical insights about samurai and bushi while walking through the plaza, blending cultural education with the immediate physical experience of the heat. It serves as both a travel warning about summer conditions in Japan and a community check-in during a challenging time.

Japan Travel Tips
- Avoid Summer Afternoons: Temperatures in Tokyo during August can exceed 38°C (100°F) with high humidity, making outdoor activities dangerous.
- Hydration is Key: Use vending machines to buy sports drinks like Pocari Sweat or Aquarius to replenish electrolytes.
- Surface Heat: Be aware that metal objects (like train statues) and asphalt can reach over 50°C (122°F); do not touch bare skin to them.
- Obon Season: Mid-August is Obon (summer holiday); business districts like Shinbashi may be quieter, but travel routes (Shinkansen) can be crowded with people leaving Tokyo.
- Cooling Centers: Convenience stores (7-Eleven, Lawson, FamilyMart) are good places to escape the heat briefly.
- Humidity Factor: The humidity index can make it feel significantly hotter than the actual temperature; dress accordingly.
Japanese Language & Culture Notes
- Suica (スイカ): A rechargeable contactless smart card used for transport and purchases. John also shows his Kitaca (キタカ) from Sapporo.
- Obon (お盆): A Buddhist custom to honor the spirits of one's ancestors, occurring in mid-August. Many businesses close, and people travel to hometowns.
- Bushi vs. Samurai: John explains that bushi (武士) were skilled warriors, while samurai were specifically those who served a master (daimyo). A ronin was a samurai without a master.
- Bushido (武士道): The moral code of the bushi, meaning "the way of the warrior."
- Mugi cha (麦茶): Barley tea, a caffeine-free summer staple often consumed cold to replenish vitamins and minerals.
- Heatwave Terminology: John refers to the "asphalt jungle" effect where concrete traps heat, making cities hotter than surrounding areas.
Food & Drink Guide
- Pocari Sweat (ポカリスエット): 00:06:10 A popular ion supply drink made by Otsuka Seiyaku. John seeks this out specifically for hydration.
- Aquarius: 00:06:10 Another sports drink option found in vending machines.
- Ice: 00:08:15 Purchased at 7-Eleven. John notes buying ice alone is sometimes priced higher than buying a coffee.
- Mugi cha (麦茶, barley tea): 00:25:35 Found in vending machines, noted for having vitamins good for summer replenishment.
- Jasmine Tea: 00:25:35 Another vending machine option John considers.
- Haagen-Dazs: 00:24:25 Ice cream John plans to buy on the way home to share with Kanae.
People

00:00:43 John Daub: [Japanese speaker with occasional Japanese place names, food terms, and cultural words.]
00:01:15 John Daub: Tokyo Olympics committee wants to hold it at this time next year. It's the hottest temperature in Japan, and we're in front of Shinbashi Station (新橋駅). I came here because it's pretty much an asphalt jungle. If there's going to be a super hot place, it's going to be Shinbashi because of this open area. It's also a place where I can social distance. I'm going to take you around this area just a little bit. I know that this phone is going to overheat in this insane temperature. I believe it's hotter than 35, 36 degrees. Earlier it got up to 38 degrees Celsius, which is well over 100. I think it was like 103. If you have a fever, that's a fever.
00:01:34 John Daub: The news was showing that at the pools, at the places that check people's temperatures when they go in, it's hotter. It's so hot that it would be the same temperature as if you had a fever. So it's very hard to read the temperature dials of who has an infection and who doesn't. That's something new that I didn't think about. 38 degrees Celsius is 101. The hottest temperature on record is from Kumagaya in Saitama. There's a locomotive in front of Shinbashi Station. Let me show you on the news here. They showed the list of the top 10 places. Kumagaya is number one on the list. It's 41.1 degrees Celsius, which is close to 108 degrees Fahrenheit or more. That was two years ago, 2008, July 23rd. We've had some hot temperatures just in the last 15 years, but they haven't really been measuring it accurately for that long.
00:02:17 John Daub: This is the heat radar map from a few hours ago. You can see Tokyo. The other places aren't as bad as the city. It might be because this is just an asphalt jungle, and all the heat gets trapped in the surrounding mountains, just Mount Fuji right over there. That creates, like, it all bottles up in the city of Tokyo. So it's hot. Purple, by the way, purple means it's above 35 degrees. It's like lava. The news crew right here showed that the temperature of this locomotive was over 50 degrees Celsius, which is incredible. The sun has been soaking up into the metal on this locomotive, and it's over 50 degrees, according to the radars that they have there. They're about to go live as well in the distance there.
00:03:27 John Daub: I'm going to go hit a vending machine or a convenience store. There's a 7-Eleven just right over there. People often say your live streams are a little bit too long, but there's a reason why. Because people don't get the notifications right away. It's a live stream, people. Everybody who is saying right now there's people living in the desert, like in Arizona and in Delhi, India. That might be the exception. But your temperatures are like 48 degrees and 50 degrees in the desert. It's a dry heat. It feels like 52 right now. They add in the humidity index and tomorrow is supposed to be even hotter. It's supposed to be 66% humidity, possibly getting up to 70 tomorrow. 70% humidity. Basically, you're swimming in water. You can't see it, but if you go like this, you're basically swimming in the humidity. That's how bad the humidity is. Humidity right now was at 60, 64% when I left and it's gonna get even more humid tomorrow. Factor in humidity because the desert can be really hot but also the humidity just drains you. It feels a lot hotter because of it.
00:06:10 John Daub: We're going to go get some drinks here, kind of soak up the sun safely and see how hot this dog is. Oh man, you're so hot, I'm so sorry. Somebody has to cool you down. Oh you could cook an egg on that. Wow, it's just a little bit after 3 p.m. I can't even get my hands on it. All right, let's go ahead to a vending machine. I'm gonna come back to this plaza in a couple of minutes, maybe we can run a test how long does it take to melt ice. The only saving thing for today is there is a breeze as you can clearly hear here in the microphone. Wow it's so hot. Let's go get a drink inside. I got my Suica (スイカ, touchless IC card). This is my Kitaca (キタカ, Sapporo version of Suica) which is from Sapporo, I like the flying squirrel. We're gonna go cool down a little bit in the 7-Eleven and get a drink, maybe get some ice. Hot Aquarius. Oh there's no Pocari Sweat (ポカリスエット, sports drink). Oh down here there's the Pocari Sweats.
00:08:15 John Daub: I could make this into a hot iced coffee, see there, but I'm just gonna take the ice, you can keep the coffee. Just buying ice is more expensive than buying a coffee, isn't that crazy? They want to get you hooked on their coffee, they sell the ice cheaper. Pocari Sweat in the house. This is made by Otsuka Seiyaku (大塚製薬, pharmaceutical company).
00:10:12 John Daub: Let's go melt some ice. You can see them right there broadcasting in the center. They have the thermal thermometer but over here you can see that pigeon that is a smart pigeon. He's hanging out underneath the cool steamer. That's one smart pigeon. Okay let's melt some ice. The best live streams are when you just melt ice. It's a race between these two here, who's gonna win, left or right one? Go go go, oh it's melting so fast. Look at that one going, it looks like it's gonna win, the left one. Some people are saying the right one, some people are saying the left one. Let's get it. I don't want any vibrations, this is very important, this is an experiment, kids everywhere around the world with their parents are now studying the effects of heat on ice. Go go go. I think that big one on the left is gonna win, they're really going at it now. Look at it catch up, the big one's really doing well. Look at it go, fight. Now they're both about the same in a way. The big one's got a huge puddle around it and the small one on the right side, it's starting to catch up though. Both puddles are getting big as people walking by me are staring at me like I'm a freak. I promise you this is grounded in science.
00:14:05 John Daub: The smaller one looks like it's got the upper hand now but the bigger one is closer to the sun. The water around it is starting to boil. The temperature is a balmy 96 degrees Fahrenheit, 36 degrees Celsius. The final turn everybody, oh we see some movement as it glistens in the sun. Glistening means pure heat. The left one is about 10%, the right one is about 10% too. It's gonna be a battle to the end, it's very close. This is the final 30 seconds of this. Basically you can see that it's really really hot, okay you get the point. Does anybody really want to stay here and keep looking at this? I think that that one won, can we declare it a winner? It looks like the small one has won, the small one has defeated the big one. Good job small one, I very much respect the little guy.
00:16:43 John Daub: Now it's time to appease the gods here, I put some ice in the tiger's mouth. If you come to Shinbashi remember the time that we cooled down the tiger, the lion. He's dripping the water, that's good. I'm cooling him down, it's a lion yeah. That's how hot it is everybody, we're cooling down this lion.
00:19:06 John Daub: I want to leave you with this as I walk into the shade. I came a little bit later, it was just too hot in the afternoon. Kanae is melting back at home. We have an air conditioner going and two fans, it's not enough. Japanese summer is always going to be really hot. A lot of people don't realize actually how hot Japan is. Those of you who have been to Japan before have felt the heat in August, end of July, at the end of the rainy season until about August 25th. It is hot. You will not experience something at this painful level until you get to Japan and realize that all of your shirts will be drenched in sweat. There's no way around it. It's hotter than Delhi in India, and I've been to Delhi. Few other places feel hotter than Tokyo in summer. Next year when you watch the Olympics, if they take place, I want you to remember this live stream because this is when the Olympics would be ending. This would be the end of the Olympics. This would be crazy. The opening, the closing ceremony, people will be collapsing in the streets. It's not too late to delay the Olympics until autumn of 2021. Please, Olympic Committee. I know you watch the show. Please delay the Olympics until autumn, at least October 2021. I think that October, which is when the 1964 Olympics were held. Please don't hold the Olympics in the center of summer. It's insanely hot. People are melting. There used to be six times more people here, they've all melted. Even the TV is leaving, they're too hot. And I'm melting as well.
00:20:55 John Daub: Some quick updates because of the pandemic. A lot of events have been canceled here in Japan. As a result of losing the fireworks festivals, this has been a really sad year for a lot of people. A lot of people lost jobs, family trips, businesses. I had the opportunity last year to sponsor some fireworks at a big event, but they canceled it. I was talking with the fireworks association and they said, why don't you just hold your own? So I started a Kickstarter. Now we're over 50 percent funded. It's a Kickstarter for Only in Japan Fireworks Festival October 2020 in Akita Prefecture somewhere. We're getting closer to that 100 percent goal, and then we're going to do stretch goals to try to make the event even longer. I'm making a 4K documentary of the process and we are hiring professional fireworks makers. These are not Roman candles and sparklers people. These are the professional shells that we get to launch from cannons. You want to be a part of this. Please do support. You don't have to actually buy anything, you just give us support because I'm going to be live streaming this for free anyways. All the backers who support with something, I'll put your name in the documentary as well, as a way to say thank you. Congrats on 50,000. Yes! 50,000 in the new channel in about a month. We launched this channel a little bit over a month ago and we're back at 50,000 subscribers. We're closing in on 100,000, I'm very optimistic. Subscriber numbers don't mean that much to me because whether it's one subscriber or a million, you treat every subscriber with as much respect because they are investing in your show by pushing that subscription button.
00:24:25 John Daub: The fireworks project is 50% funded and we reached 50,000 subscribers, it's a great day to celebrate, maybe not outside. So I'm going to go back to Kanae and have some ice cream and pick up a Haagen-Dazs on the way home. There's some pretty neat flavors. Thank you to everybody, also stay safe and stay cool, stay inside. Just getting out of this heat is enough reason not to go outside. Does anyone have any questions? Let's go to a vending machine, let's see if we can find something stronger than a Pocari Sweat. You can social distance here, you can kind of stay away from people. Let's go to that Pikachu vending machine over here.
00:25:35 John Daub: Ryan, hey John stay cool man. Do you prefer winter in Hokkaido or summer in Tokyo? Summer in Tokyo. Yeah, I'm really sad to see that Sega number 2 building go but who knows what will take its place, maybe something better, something bigger. Every single industry, every single business is taking a hit. I'm sure that the fact that foreign tourists aren't here played a huge part in that building closing. So come back soon everybody. Relaxed Jasmine Tea, I could use some of that. There's the Pocari Sweat, I didn't have to go into the convenience store. Mugi cha (麦茶, barley tea) is a favorite in Japan, it has some vitamins in it which is good to replenish in the summer. I didn't sleep for two days and I slept last night and I woke up at 12 because I was editing the Kanazawa video for like two weeks because the audio was really bad and there was a flicker in all of the scenes. Kanazawa 400 year old food, a menu from a restaurant that used to serve daimyo (大名, feudal lord). The same family I believe, the chefs have continued those recipes since the Edo period, which is pretty cool. They didn't have tempura or anpan or yakisoba back in the Edo period. These are kind of like new recipes but they served some old ones that they would give to bushi (武士, warriors) or daimyo. In Kanazawa they had more bushi, less samurai, and there's a difference between bushi and samurai. Samurai were probably bushi but samurai served the daimyo. Kanazawa was one where being a bushi meant that you were just really skilled warrior meaning that you could probably knit a sweater and you could also use your sword and smash people.
00:28:50 John Daub: Alright let's go back to my bicycle. We're going to walk across the plaza of heatstroke and make our way to the other side. Bushido (武士道) is the code of bushi, do meaning route, bushi meaning skilled warrior. Samurai are those that serve the government so you had to have a master. Ronin were samurai who no longer had a master. Bushi could not be technically ronin because they never had a master. Kanazawa was the perfect place to make that kind of a video. Again this train had a temperature of over 50 degrees, which is like 108 or something. They should make that the Olympic torch, right? Have the relay runners make a quick pit stop at Shinbashi to light the nudie tower. Do you see this here, I believe these are 5G signals for Docomo (ドコモ). 5G is here, that makes sense that they would use the phone booths to run the 5G. Here's the Ebisu (恵比寿, god of prosperity) god of lottery.
00:30:04 John Daub: Ryan will you and Kanae go to the Olympic opening ceremony? Probably not but I might go outside the Olympic opening ceremony. Tickets are $3000 for the opening ceremony, I'm not gonna pay that kind of money. I'll live stream from outside the Olympic stadium, maybe that's a lot better. I couldn't understand the process, me and Kanae were frustrated we just stopped bidding on tickets. We have no event tickets, we stopped caring about attending the Olympics so we'll see it from the outside. Koyasan and Karuizawa and a lot of places but right now we shouldn't be traveling anywhere. Tokyoites have been asked to stay in Tokyo during the holidays but that has not happened. People are riding the Shinkansen and public transportation less, everybody has been getting into cars and driving outside of Tokyo and that has led to increase in infections. People have moved on but the virus has not.
00:32:46 John Daub: I'm not going to Tokyo Station, I'm too hot for that. Oh man it's sticking to me. Stay cool everybody. Just to check in on the ice that I bought, it's all melted and it tastes good. Flashbacks of Naked Man Festival in February, oh man that was so worth it. This is the part that most YouTubers just cut when they edit it but in a live stream we just keep going. Then the moment is over, the ice has melted, look at that it's gone. What was once was is no longer.
00:34:02 John Daub: I want to make sure I didn't miss anybody. Thank you. Tomorrow we have, tonight I'm going to be uploading the Kickstarter fireworks video onto YouTube here so tonight which is tomorrow morning your time you're going to get a chance to see that. I do have a midnight snack run coming just as soon as people start to go home. I'm a little bit worried about being out right now, there's not a lot of people in the area because this is a business area and nobody's at the office today, it's Obon (お盆, summer holiday) so this is a little bit safer at this time than it usually would be. I can't wait to go back, I get so many friends in Uppsala and Stockholm and Småland and Göteborg. Alright everybody have a good day, have a good night wherever you are in the world. Stay cool, thanks for hanging out with me and whatever you do make sure you keep your head on, stay smart, wear a mask stay safe unlike this guy.
