Hokkaido Weather in June — The Only Corner of Japan Without a Rainy Season, and Lavender Just Beginning

Quick answer: Hokkaido weather in June brings an average of 17°C, a high of 21°C, a low of 12°C, and just 60mm of rain for the month, based on long-term averages from the Japan Meteorological Agency. It is the only region in Japan spared by the mainland tsuyu (rainy season), giving travellers the country’s most comfortable early summer. Compared with London or Seattle in June, Sapporo feels similar in temperature but noticeably drier and sunnier. Lavender starts blooming in the last week of the month, the Hokkaido University Festival (Hokudai-sai) fills Sapporo with food stalls, and daylight stretches past 7:30 PM — arguably the golden month for an outdoor road trip.

Hi there! This is GO!GO!TOUR, your English-language partner for renting cars and booking activities across Japan. Hokkaido — Japan’s northernmost prefecture — is home to Sapporo, Otaru, Furano, Biei, Lake Shikotsu and Niseko, all connected by wide open roads and cool northern air. Locals will tell you flat-out: June is Hokkaido’s most comfortable travel month, because the humidity that makes Tokyo miserable simply never arrives up here. Hokkaido weather in June also shapes how you’ll get here: New Chitose Airport (CTS) has direct flights from Singapore, Bangkok, Taipei, Seoul, Hong Kong and multiple US/AU gateways via Tokyo. From the moment you land, you can be at Lake Shikotsu in 40 minutes or the Furano lavender fields in 2 hours 30 minutes — provided you drive yourself. In this guide, we cover Hokkaido June weather the way an actual traveller needs it: temperature and rainfall data, a packing list you can use straight out of the article, deep dives into every spot pictured (Shikotsuko, Horomitoge Lavender, Hokudai Festival, Morappu Campground, Moss Corridor, Hanacha Farm Cafe), why a rental car changes the trip entirely, and answers to the questions travellers ask most. Hokkaido weather in June at Lake Shikotsu in June — a traveller paddles on a paddleboard over crystal-clear caldera water The photo above shows Lake Shikotsu, arguably the clearest snapshot of Hokkaido weather in June. It is a caldera lake with water clarity that ranks in Japan’s top three every year — you can see 5 to 10 metres down from the surface. The water is still cold in June, but SUP, canoe and clear-bottomed kayak tours are already running, since none of them require you to actually get wet. To reach places like this without wasting half a day on infrequent buses, book a rental car from day one. Public transit in Hokkaido is thin outside Sapporo, and even the JR lines take unexpected detours. GO!GO!TOUR Hokkaido rental cars handle everything in English — quotes, insurance, ETC cards, airport pickup — so the drive starts smoothly the moment you clear customs.

What to Pack for Hokkaido in June — Layering Beats Everything

Hokkaido in June sits at temperatures Londoners or Seattle residents would call “a cool spring day” — warmer than April, cooler than August. If you are flying in from Southeast Asia or Australia, expect a 15°C drop from what you left behind. If you are flying in from the US East Coast or Europe, it will feel almost identical to home. The rule that works everywhere: think in layers, not in outfits. Daytime is short-sleeve weather, but early mornings, evenings, and rainy hours all drop into the low teens. Packing list for June Hokkaido:
  • Daytime (16–21°C): T-shirt or long sleeve + light pants or a skirt. Active travellers can add a thin jacket for wind.
  • Morning & evening (12–15°C): A light jacket, windbreaker or hoodie is essential.
  • Rainy day: Waterproof jacket + compact umbrella. Rain drops the perceived temperature to around 10°C.
  • Water activities: SUP and kayak operators provide wetsuits and life vests — bring a change of clothes and a towel.
  • All day: UV 7–8 means sunscreen, a brimmed hat and sunglasses are non-negotiable, plus a light cardigan for over-cooled indoor spaces.
Suitcase test: if your outfit works for a June evening in Seattle or an April afternoon in Milan, you are ready for Hokkaido.

The June Highlights of Hokkaido — Every Spot in Our Photos

June in Hokkaido lets you combine nature, festivals and cafes into a single loop. Here is every location shown in this article, in the order you might actually visit them.

1. Horomitoge Lavender Farm — Sapporo’s Early-Blooming Lavender Hill

Hokkaido June weather at Horomitoge Lavender Farm overlooking Sapporo — a hillside covered in lavender rows above the city The Horomitoge Lavender Farm sits on a hill just 20 minutes by car from central Sapporo. It is the “lavender field inside the city”: you can shoot flowers by day and Sapporo’s night skyline once the sun sets. Perfect for travellers who do not want to spend an entire day driving to Furano and back.
  • Address: Bankei 4-chome, Chuo-ku, Sapporo
  • Bloom period: Last week of June → peak mid-July
  • Admission: Free during the day / around ¥500 parking fee at night
  • Season: Late June to late July only
  • Drive time: About 60 minutes from New Chitose Airport
Locals treat Horomitoge as a famous Sapporo night-view spot as well. Shoot lavender in golden hour, then wait for the city lights — a proper “two-in-one” evening.

2. Hokudai Festival (Hokkaido University Festival) — 100+ Student Food Stalls

Hokkaido University Festival — students running food stalls and exhibitions across the campus The Hokkaido University Festival (Hokudai-sai) takes over the campus for four days in early June, right in central Sapporo. Students run every stall, every exhibit and every performance. Entry is free and open to anyone walking through the gates.
  • Address: Kita 8 Nishi 5, Kita-ku, Sapporo (Hokkaido University campus)
  • Dates: Four consecutive days in early June (Thu–Sun)
  • Admission: Free
  • Access: 10-min walk from JR Sapporo Station
Over 100 different food stalls line the paths between old brick buildings. Try Hokkaido butter potatoes, ramen, takoyaki and craft beer at student prices (¥500–800). If your Sapporo dates line up with early June, this event alone is worth planning around.

3. Morappu Campground — Waking Up on Lake Shikotsu

Morappu Campground — tents set up along the shore of Lake Shikotsu on a June morning Morappu Campground sits on the southern shore of Lake Shikotsu. Unzip your tent and the lake and surrounding mountains fill the horizon. Morappu Campground — close-up of a camper's evening cooking setup with the lake in the background
  • Address: Morappu, Chitose City, Hokkaido
  • Season: Late April – October (June is the sweet spot)
  • Fee: Around ¥1,000 per person (tent rental available)
  • Drive time: About 40 minutes from New Chitose Airport
The site rents tents and tarps to first-time campers, so you can arrive empty-handed. June sees minimal mosquitoes and daytime temperatures around 20°C, which makes it the ideal month for a first Hokkaido camping trip.

4. Lake Shikotsu — Japan’s Clearest Water Playground

Lake Shikotsu SUP experience — clear water lets you see straight to the bottom Lake Shikotsu has topped Japan’s Ministry of the Environment water-clarity ranking repeatedly. Visibility easily reaches 5–10 metres, and the caldera walls give the surface a striking turquoise glow.
  • Address: Shikotsuko Onsen, Chitose City, Hokkaido
  • Recommended activities: Clear SUP, clear-bottom kayak, diving tour
  • Price: SUP around ¥6,000 / clear kayak ¥8,000 (2 hours)
  • Drive time: About 40 minutes from New Chitose Airport
The magic moment is looking straight down through a clear kayak into the depths of the lake. Swimming is off the table with 12°C water, but SUP and kayak trips only require a 30-minute intro session and beginners are ready to go. The colour in the photo is not a filter — it is exactly what your eyes will see.

5. Moss Corridor (Koke no Kairo) — A Mystical Green Canyon

Moss Corridor — walls of a canyon completely covered in vivid green moss The Moss Corridor (Koke no Kairo) hides in the forests near Lake Shikotsu — a little-known “mystical spot”. Walk down the trail and both walls of the canyon are drowned in bright green moss from top to bottom. Moss Corridor — dense moss growing over ancient rock formations
  • Location: West of Lake Shikotsu (map apps: “苔の回廊”)
  • Note: Not an official tourist site — a guided tour is required as it sits inside managed forest land
  • Tour price: From about ¥5,000 (half-day)
  • Best month: June — moss colour is at its most vivid
  • What to wear: Trekking shoes and long pants (mosquitoes, tall grass)
June’s spring rains leave the moss saturated, producing the deepest possible green. Photographers should absolutely book this one: it looks straight out of a Studio Ghibli forest scene.

6. Hanacha Farm Cafe — Farm-to-Cup Soft Serve near Chitose

Hanacha Farm Cafe — Hokkaido soft-serve ice cream and seasonal parfait on a wooden table Hanacha is a farm cafe in Chitose that runs on 100% ingredients from its own fields. It has become a fixed stop for locals and tourists driving between Shikotsu and New Chitose Airport.
  • Address: Neshikoshi 8-chome 6-2, Chitose City, Hokkaido
  • Signature: Farm milk soft serve, blueberry smoothie, seasonal fruit parfait
  • Price range: Soft serve around ¥500, parfaits from ¥1,000
  • Drive time: About 15 minutes from New Chitose Airport
  • Open: Daily in June (occasional irregular closures)
The richness of milk pulled from the farm that morning is a different league from any premium ice cream at home. Locals recommend saving Hanacha for the last day, on the way back to the airport — a proper Hokkaido send-off.

Hokkaido in June = A Road Trip. Here’s Why.

Unlike Tokyo or Osaka, Hokkaido is where a rental car is not a luxury but a requirement. Three concrete reasons:
  • 1. The distances are big. Sapporo to Furano is 2h 30m, Sapporo to Otaru 40m, Sapporo to Lake Shikotsu 40m. JR and bus schedules are sparse and often require transfers.
  • 2. The best places are in the middle of nowhere. Lavender fields, lakes, ranches, canyons — the highlights of Hokkaido sit exactly where public transit does not.
  • 3. June weather is perfect for driving. No snow, low rain, and 15+ hours of daylight — you can cover 700km in a day without stress.

Hokkaido June Weather FAQ

Q1. Does Hokkaido have a rainy season in June?

Officially, Hokkaido is the only region in Japan not affected by the mainland tsuyu. Late June and early July can bring a few grey days locals call “Ezo tsuyu”, but it is a light drizzle — not the heavy rain seen in Tokyo. At around 60mm total rainfall for the month (less than half of Tokyo), it has virtually no impact on your itinerary.

Q2. Give me the packing list in one line.

T-shirt + light pants for daytime, thin jacket or hoodie for mornings and evenings, waterproof jacket for the odd drizzle. If you would dress this way for London or Seattle in June, you are done.

Q3. Can I see lavender in June, or do I have to wait for July?

Lavender starts blooming in late June and peaks in mid-July. From roughly 25 June onward, both Horomitoge Lavender (20 min from Sapporo) and Furano’s Farm Tomita show early varieties. Bonus of visiting in June: far fewer tourists than July, so photos are much easier.

Q4. Can tourists join the Hokudai Festival?

Yes — entry is free and unrestricted. Four days, early June, Thursday to Sunday. From JR Sapporo Station it is a 10-minute walk. With over 100 food stalls and evening performances, it is one of the best cheap-and-fun nights you can have in Sapporo.

Q5. Can I swim in Lake Shikotsu in June?

No, the water is around 12°C — too cold to swim. Instead, join a clear-bottom kayak, SUP or diving tour. Operators supply wetsuits and life vests, and 30 minutes of instruction is enough for beginners.

Q6. Do I need snow tires for a June rental car?

No. Snow tire season ends by late April; every rental car in June comes with summer tires as standard.

Q7. Where do I get an eSIM and coupons for the trip?

GO!GO! eSIM offers 5GB/5 days from ¥1,980, and GO!GO!TOUR coupons lists active discount codes for rental cars, eSIM and activities.

Wrap-Up — Cool Air, Long Days, and Early Lavender — Hokkaido’s Best-Kept Summer Secret

June is when Hokkaido gives you Japan without the humidity — with a lavender headstart on the crowds of July. Daytime temperatures of 17–21°C, less than half the rainfall of Tokyo, and daylight past 7:30 PM: everything about this month favours a slow, road-trip pace through Hokkaido’s wide open landscapes. Everything you need to remember:
  • Average 17°C, high 21°C, low 12°C — think Seattle or Milan in April
  • 60mm rainfall — around a quarter of Tokyo; a folding umbrella is enough
  • 15h 30m of daylight — pack the itinerary loosely; you have time
  • Thin jacket, waterproof shell — SUP and kayak for the water days
  • Horomitoge Lavender opens late June
  • Hokudai Festival in early June + Shikotsuko, Moss Corridor, Hanacha
  • Rental car is effectively required — public transit cannot reach the highlights
