June in Yokohama is tsuyu, the rainy season. The Japan Meteorological Agency typically declares it for the Kanto region in early June, and it holds through mid or late July. Daytime highs average 26.0°C (79°F) while nights settle around 19.4°C (67°F), and the air feels warm and damp, a bit like a bathroom after someone else's shower. Most rain days bring grey drizzle rather than typhoon drama, though the harbor promenade from Osanbashi Pier to Yamashita Park loses most of its appeal under a low ceiling of cloud.

The upside is real. June is the one month in the Japanese calendar with no national public holiday, so domestic crowds drop sharply after Golden Week in early May. Hydrangeas bloom across the region, from the slopes of Sankei-en in Honmoku to the temple gardens of Kamakura, 25 minutes down the JR Yokosuka Line, and around June 2 the city marks the 1859 opening of its port with fireworks over the water in Minato Mirai.

So is June worth it? For a flexible traveler with an umbrella, it probably is, with fewer tour groups in Chinatown and cheaper rooms than in spring. For a first-timer who wants clear views of Mount Fuji from the Landmark Tower, it is a poor bet. Haze and cloud hide Fuji on most June days.

Why visit in June

Japan has no national holiday in June, so Motomachi and Yokohama Chinatown are noticeably calmer than during Golden Week in early May.
Hydrangea season peaks in mid to late June, and Kamakura's temple gardens are 25 minutes away by train.
Irises bloom in early June in the ponds of Sankei-en, the Honmoku garden that opened in 1906.
Aji (horse mackerel) and Shonan shirasu are at their best, and Noge's standing bars put both on their chalkboard menus.
Days are long: sunset comes close to 7pm around the June 21 solstice, which leaves light for a dry evening walk along Yamate Bluff.

Worth knowing

Rain falls on roughly half the days in June, and grey skies often last for a whole week at a time.
Humidity makes 26°C feel closer to 30°C by late afternoon, and shirts cling within 15 minutes of walking from Sakuragicho to the Red Brick Warehouse.
Kanagawa beaches like Yuigahama in Kamakura have no lifeguards or beach huts until the swimming season opens in early July.
The Yokohama Air Cabin ropeway over the harbor and the Sea Bass water bus can stop running in strong wind or lightning.

Best for

Think twice if

Weather measured 26° / 19°C 185mm rain · 14 rainy days · 81% humidity rains perceptibly ~2.5h/day · 82% of mornings dry

Crowds medium

Pack Pack quick-dry synthetic or linen shirts, lightweight trousers or skirts that dry in a few hours, water-resistant sneakers or sport sandals, a compact umbrella, and one thin long-sleeve layer for air-conditioned trains and museums.

Expect about 185mm (7.3 inches) of rain across roughly 14 wet days, most of it steady drizzle with the occasional downpour when a front stalls overhead. Average humidity is 81%, which means laundry barely dries in a hotel room. Early June can still produce a few bright, breezy days before the rainy season settles in, but the last week tends to feel heavier and warmer. Think of it as a preview of July, when highs climb past 30°C (86°F).

Seasonal caution

When a rainy-season front stalls over Kanto, it can bring an hour or two of torrential rain, at which point the JMA issues heavy-rain advisories and trains on the Keikyu and JR Yokosuka lines sometimes slow down or stop.
In late June the Ministry of the Environment begins issuing heatstroke alerts for Kanagawa, because humidity above 80% raises the risk well before the thermometer looks dangerous.

Best things to do in June

Hydrangea day trip to Kamakura

day trip

Take the JR Yokosuka Line to Kita-Kamakura for Meigetsu-in, whose pale blue hydrangeas earned it the nickname Ajisai-dera, then walk or ride the Enoden to Hase-dera, where the hillside hydrangea path looks out over Sagami Bay.

Kamakura's hydrangeas peak from mid to late June, and the rain deepens their blues and purples.

Booking tipOn busy June weekends Hase-dera often hands out numbered entry tickets for the hydrangea path, so arrive before 8:30am or go on a weekday.

Irises and hydrangeas at Sankei-en

garden

This Honmoku garden holds historic wooden buildings moved from Kyoto and Kamakura, all arranged around a large pond you can loop in about 90 minutes.

Hanashobu irises fill the marsh beds in early June, and hydrangeas follow later in the month.

Booking tipTake a bus from Yokohama Station or Sakuragicho Station, as the garden is not on a rail line.

Yokohama Port Opening fireworks

festival

Watch the harbor fireworks from Rinko Park or the Osanbashi Pier deck in Minato Mirai, where food stalls line the waterfront from the afternoon on.

The show celebrates the port's anniversary and runs in early June.

Booking tipHarbor-view restaurants and hotel rooms facing the bay sell out weeks ahead, so book by early May.

BayStars interleague game at Yokohama Stadium

sports

The DeNA BayStars play at the 1977 ballpark next to Yokohama Park in Kannai, where fans sing through all nine innings and the stadium brews its own beer.

Interleague play brings Pacific League teams such as the SoftBank Hawks to Yokohama, a matchup you can see here from late May to mid-June and nowhere else.

Booking tipWeekend tickets go on sale about a month before each game, and the outfield seats are the cheapest and the loudest.

Rainy-day history loop in Kannai

museum

Visit the Yokohama Archives of History, housed since 1981 in the former British Consulate, then walk to the Silk Museum and the Kanagawa Prefectural Museum of Cultural History.

All three sit within a 10-minute walk of each other, which makes a natural plan for June's wettest afternoons.

Firefly evenings at Sankei-en

nature

The garden stays open after dark so visitors can watch Genji fireflies (hotaru) blinking along its streams.

Fireflies appear for only a few weeks, from late May into early June, on warm, humid nights.

Booking tipCheck Sankei-en's schedule in May, since the evening dates change with the season.

What to eat in June

In season: fruit

Yamagata sakuranbo (cherries)
Satonishiki cherries from Yamagata peak from mid to late June, and you'll find them in the food halls under Yokohama Station.
Biwa (loquat)
Loquats from the Boso Peninsula and Shizuoka have a short season in June, pale orange fruit that tastes faintly of apricot.

On menus now

Nama shirasu-don
The Shonan shirasu catch is strong in early summer, and raw baby sardines over rice are a Kamakura and Enoshima specialty, served on days when the morning boats go out.
Hiyashi chuka
Restaurants in Yokohama Chinatown switch on their cold ramen menus as the humidity rises in June, serving chilled noodles with sesame or soy-vinegar dressing.

In markets

Aji (horse mackerel)
Aji from Sagami Bay is fattest in June, and the izakaya in Noge serve it as tataki or as crisp aji-fry.
Ume and new umeshu
Green ume plums reach Kanagawa supermarkets in June, the season when households steep umeshu and bars pour ume sodas.

Your packing checklist

0 of 8 packed

Compact folding umbrellaRain arrives on about half of June's days, and since shops and museums provide plastic umbrella sleeves or stands at the door, a small folding umbrella is easier to handle than a long one. Shop
Water-resistant sneakers or sport sandalsThe brick paving around the Red Brick Warehouse and Yamashita Park stays wet for hours after rain, and canvas shoes soak through in about 10 minutes. Shop
Quick-dry shirtsCotton rarely dries overnight in Yokohama's June humidity, even in an air-conditioned room. Shop
Thin long-sleeve layerTrains on the Minatomirai Line and museum galleries are often cooled to about 22°C (72°F), a big drop from the damp air outside. Shop
Tenugui or small hand towelMany public restrooms in Japan have no paper towels, and people also carry a tenugui to wipe off sweat on June's walks up to Yamate. Shop
Insect repellentMosquitoes breed quickly in the ponds at Sankei-en and the temple gardens of Kamakura once the rainy season starts. Shop
Waterproof phone pouch or zip bagsKeep your phone in a waterproof case or a bag if you plan to photograph the hydrangeas in Kamakura during a downpour. Shop
Spare socksTemples including Hase-dera ask you to remove your shoes before going inside, and wet socks on tatami are a discomfort worth avoiding. Shop

Insider tips

In June, a forecast of 'rain' often means drizzle in the morning and a dry spell after 3pm, so check the hourly radar on the JMA website or tenki.jp before cancelling outdoor plans.
A covered route runs from Sakuragicho Station along the moving walkway into Landmark Plaza and Queen's Square, letting you cross most of Minato Mirai with barely a raindrop.
Kita-Kamakura Station is a short walk from Meigetsu-in, so get off there, one stop before Kamakura Station, and you'll beat the crowds walking up from the main station.
The izakaya in Noge write the catch of the day on a paper board by the door. If aji-fry or nama shirasu is listed, order it before 8pm, when it often sells out.
Convenience stores in Yokohama sell vinyl umbrellas near the entrance, and locals often leave them behind in train racks during June.

Avoid these mistakes

If you head to Hase-dera in Kamakura around noon on a June Saturday, the wait for the hydrangea path can run past an hour. A weekday at opening time is a better call.
If you're planning a Shonan beach day in June, know that beach huts, lifeguards and changing facilities at Yuigahama and Enoshima don't open until the July swimming season.
Booking a rooftop view of Mount Fuji weeks ahead is a gamble in June, when haze hides the mountain on most days. Decide on the morning, once you can see whether the sky is clear.
Packing nothing but cotton clothes in June will leave you with damp clothing for days, and laundry left in a hotel room can smell musty by the second morning.

Practical tips for June

Most museums in Kannai and Minato Mirai close on Mondays, so plan rainy Mondays around shopping in Motomachi or the food halls at Yokohama Station. The Yokohama Air Cabin and the Sea Bass water bus can stop running in strong wind, so check their websites before heading out. Tipping is not customary in restaurants, taxis or hotels. Hotels around the harbor fill up quickly for the port-anniversary weekend and for big weekend shows at K-Arena Yokohama, so book those dates early. A Suica or PASMO card covers JR, the Minatomirai Line, Keikyu, the Enoden and city buses.

FAQ

Is June a good time to visit Yokohama?

It is a fair month, not a great one. Rain and humidity limit time outdoors, but crowds are thin, rooms are cheaper than in spring, and hydrangea season in nearby Kamakura is one of the region's best seasonal sights.

What is the weather like in Yokohama in June?

Warm and damp is the honest summary: the rainy season typically arrives in the first week of June, bringing frequent drizzle, overcast skies, and a humidity that makes Yokohama feel warmer than any thermometer will tell you, particularly after mid-month.

Is Yokohama crowded in June?

Less than usual. Japan has no public holidays this month, so domestic visitors mostly stay home, which means busy weekends in Kamakura's temple gardens and near the harbor on the port-anniversary evening, and calm weekdays in Chinatown.

Can you see Mount Fuji from Yokohama in June?

Rarely. Cloud cover and summer haze usually hide Fuji from June through August, and if you want a reliable sighting from Minato Mirai, December and January are the months to plan for.

Is it worth going to Kamakura from Yokohama in June?

Yes, it is the best reason to be in the area this month. The JR Yokosuka Line from Yokohama Station runs frequently, and if you go on a weekday morning you get the hydrangea gardens with a fraction of the weekend queues.
