Rainy Season in Japan Is Better Than Everyone Warned You

# Rainy Season in Japan Is Better Than Everyone Warned You

Kenji Matsumoto has been selling umbrellas out of the same narrow shop on Koenji's Pal shopping arcade for thirty-one years. The shop is called Ame-ya — "rain shop" — and it sits two minutes from Koenji Station's north exit, squeezed between a used vinyl store and a takoyaki stand that has been there even longer. Kenji is sixty-three, with the deliberate hands of someone who has handled delicate things his whole life. He repairs umbrellas as a matter of course. He considers it mildly embarrassing that most people don't.

When I stopped in during a particularly brutal downpour last June, he was re-stringing a pale blue Totoro-print umbrella for a woman who'd had it for eighteen years. He handed it back to her wrapped in tissue paper.

"Tourists come in here afraid of the rain," he said, not looking up from the next repair job, a burgundy parasol with a cracked rib. "I always tell them: the rain is why everything is green. The rain is why the moss looks the way it does. The rain is why you're standing in a shop talking to me instead of walking past."

He had a point I hadn't properly thought about in eight years of living here.

What Tsuyu Actually Is

Japan's rainy season — *tsuyu* in Japanese, written with the characters for "plum rain" because it coincides with plum-ripening season — runs roughly from early June through mid-July in the Kanto region, a week or two earlier in Kyushu and a week or two later in Tohoku. It is not, despite what travel forums will tell you, a wall of miserable gray water that makes sightseeing impossible.

What it actually is: a cycle. Three or four days of heavy, warm, dramatic rain followed by two or three days of thick cloud with occasional sun. The temperature sits somewhere between 18 and 27 degrees Celsius depending on the week, which means you are never cold, and you are not yet in the genuinely punishing heat that arrives in late July and August. The crowds at Kyoto's major temples drop by roughly a third compared to the Golden Week peak in May. Hotel rates follow suit.

The thing nobody tells first-time visitors is that tsuyu is often the most comfortable time to actually be outside in Japan. Not comfortable in a breezy, picnic-on-the-lawn sense — comfortable in the way that a warm bath is comfortable, the air soft and close, the smell of wet stone and cedar coming off surfaces that were dusty and closed-off a month earlier.

I have walked the stone path at Kokedera, the moss temple in Kyoto's Nishikyo ward, in three different seasons. In autumn it is beautiful the way a postcard is beautiful. In tsuyu it is something else: the moss genuinely fluorescent, almost unreal, each cushion of it catching light and holding it differently, the sound of dripping water from the eaves mixing with whatever birds decide rain is not their problem.

The Part Nobody Mentions About the Food

Kenji's observation about rain slowing people down applies to eating in Japan more than almost anywhere else. When it rains, people duck into places they might have walked past. They order a second drink. They talk to the person next to them at the counter.

June is also when two specific things happen to the food supply that matter quite a bit if you pay attention.

The first is *shiso*. The herb — sometimes called perilla or Japanese basil in English, though neither translation is quite right — hits its peak around mid-June. It shows up in everything: draped over cold tofu at izakayas, folded into gyoza at places that care, blended into sauces at the kind of ramen shops that change their menu by season. At Fuunji in Shinjuku's Tomigaya neighborhood, a ten-minute walk from Yoyogi Station's north exit, the *tsukemen* (dipping noodles, ¥1,100 for a regular portion) gets a shiso-spiked broth variation in early June that the staff won't always mention unless you ask. Ask.

The second is the timing of cold-drink culture. Every Japanese convenience store and department store basement begins its serious summer prep in early June. At the basement food floor of Isetan in Shinjuku — which I will defend against all comers as the best department store food basement in Tokyo, though the Takashimaya in Nihonbashi makes a legitimate argument — you start seeing *mizuyōkan* (cold red bean jelly, ¥420–¥680 depending on the maker) arranged in refrigerated cases like jewels. The Toraya counter, specifically, handles their June *yokan* with the kind of gravity usually reserved for auction houses.

How to Move Around Without Becoming Miserable

Here is where I'll be practical, because ignoring the logistics would be dishonest.

The rain is real. Some days it comes down hard enough that your shoes will be soaked through in four minutes of walking, and no travel article can romanticize wet socks. Two things prevent most of the misery.

The first: a proper umbrella. Not the ¥500 clear vinyl ones they sell at every convenience store, though those are fine for a ten-minute walk. If you're going to spend two weeks in Japan during tsuyu, spend ¥2,500–¥4,000 on something from a place like Kenji's shop in Koenji, or the umbrella section at Loft in Shibuya (the main branch on Spain-Zaka, about four minutes from Shibuya Station's Hachiko exit). The construction difference is significant — the ribs flex rather than invert, the canopy is wider, and you won't be replacing it after one strong gust.

The second: restructuring how you think about your day's shape. Experienced Japan travelers learn to plan days around train access and covered routes, and this matters more in June than any other month. Tokyo's covered shotengai — shopping arcades with roofs — run for hundreds of meters through neighborhoods like Togoshi Ginza in Shinagawa (the longest shotengai in Japan, stretching about 1.3 kilometers) or Musashi-Koyama's Palm shopping arcade near Musashi-Koyama Station on the Tokyu Meguro Line. You can spend an entire afternoon browsing, eating, and talking to shopkeepers without once needing your umbrella.

The rain doesn't interrupt the trip. The rain is the trip — it just requires admitting that you didn't come to Japan to move fast.

For intercity travel, the Shinkansen network is essentially weather-proof, and the covered station complexes at Kyoto, Osaka, and Tokyo mean you can arrive and get oriented without stepping outside at all. Rain has almost no practical effect on Shinkansen schedules — it's typhoons, which arrive later in September and October, that cause meaningful delays.

What the Rain Does to People

I want to come back to Kenji, because he said something else that afternoon that I keep turning over.

I'd asked him whether business suffers in summer, the general assumption being that people stock up on umbrellas in June and disappear the rest of the year. He shook his head slowly.

"People come back," he said. "Not just for repairs. They come back to tell me things. They were caught in rain at Shinjuku Gyoen and watched the irises open. They had *kakigoori* — shaved ice — somewhere in Yanaka and it was the best thing they'd eaten in Tokyo. They had three hours stuck inside a shrine in Kyoto waiting for rain to stop and talked to a priest for an hour."

He set down the burgundy parasol. "The rain gives people something to do with their time that they didn't plan for. Japanese people know this. Tourists have to discover it."

He's right that the Japanese relationship with tsuyu is not one of resistance. It's one of accommodation and, in certain moods, genuine appreciation. The word *shizuka* — quiet, still — comes up a lot when Japanese friends describe what they like about the rainy season. The city becomes *shizuka* in a way it isn't possible to be in summer heat or autumn-leaf season. The pace changes.

Three Places That Are Specifically Better in the Rain

Shinjuku Gyoen is obvious, and I mention it only because it's obvious in the correct way rather than the tourist-trap way. The garden — about a twelve-minute walk from Shinjuku Station's east exit, or a five-minute walk from Shinjuku-Gyoenmae Station on the Marunouchi Line — charges ¥500 entry and has the peculiar quality of absorbing crowds. On a rainy Tuesday at 2pm it feels genuinely uncrowded even when several hundred people are inside. The hydrangeas along the French formal garden's edges bloom through June in blues and purples that have no business being that saturated in real life.

Yanaka in northeast Tokyo is a neighborhood of surviving Edo-period street layouts, small temples, and independently owned shops that has mostly resisted the homogenizing forces of the last thirty years. The main cemetery — Yanaka Reien — is a legitimate place to walk on a rainy afternoon, and I say that without irony. The old zelkova trees form a canopy overhead, the graves are moss-covered in the particular way that suggests genuine age, and almost no one is there on weekday afternoons around 3pm in June. Access is straightforward from Nippori Station on the JR Yamanote Line, less than a two-minute walk from the main exit.

The third is more of a category than a place: any small shotengai in any mid-size Japanese city during rain. Not Nakamise-dori in Asakusa, which is covered but not really a neighborhood shopping street anymore. Something like Tenjinbashi-suji in Osaka, which runs about 2.6 kilometers from Tenjinbashisuji Rokuchome Station on the Osaka Metro Tanimachi Line, and where you can get a bowl of *kitsune udon* — fried tofu on wheat noodles in a dashi broth, ¥650 at one of the lunch counters near the south end — and watch the rain sheet down beyond the arcade roof while the city continues at its own speed around you.

The Honest Part

I was wrong about tsuyu for my first two years in Tokyo. I spent both rainy seasons avoiding outdoor plans and feeling vaguely cheated, as though Japan was withholding the version of itself I'd moved here to see. It took a typhoon-adjacent rainstorm that trapped me in a small bar in Nakameguro — the kind of place that holds eight people at the counter and has one guy behind it who makes very good highballs — to recalibrate.

I was there for four hours. I tried three different whiskies I hadn't heard of. The bartender explained the difference between Japanese and Scotch production methods using a series of drawings on the back of a receipt. Outside, the Meguro River came up about a meter and then receded. When I left at midnight the air smelled like earth and cut grass.

That's the version of Japan that doesn't photograph well and that no amount of research before you leave quite prepares you for. It requires getting caught in something — a place, a conversation, a stretch of weather you didn't plan for.

Kenji probably would have told me that immediately. I just needed the rain to get me into his shop.

*Ame-ya umbrella shop is located on Koenji Pal shopping arcade, a two-minute walk from Koenji Station's north exit on the JR Chuo Line. There is no website. The shop is open Tuesday through Sunday from 11am until 7pm. If the gate is down at 6pm on a rainy day, knock — he's usually still there.*
