Tokyo in June | Image credit: victoraf via Pixabay
Ask around about Tokyo in June and you'll hear the same two words: rainy season. Those damp weeks are also when the city's gardens fill with blue and pink blooms, the crowds thin out and hotel prices often dip. With an umbrella and a flexible plan, this could be the most relaxed month to see Tokyo.
It's a quick trip from Hong Kong too. Flights take around 4 hours, Tokyo is 1 hour ahead of Hong Kong time, and HKSAR passport holders can visit Japan visa-free for up to 90 days (check the latest entry requirements before you go).
Tokyo in June at a glance
Tokyo weather in June is warm and humid, with a lot of grey sky. Think of the tsuyu (rainy season) as the moment the city's early-summer colour shows up, and June is when it kicks off.
- Tokyo rainy season:Usually starts in the first or second week of June and wraps up in mid to late July. The Japan Meteorological Agency announces the official dates each year.
- Rainfall:Around 150 to 175 mm over roughly 12 rainy days. Expect grey skies and drizzle, with the odd downpour.
- Temperatures:Highs of 25 to 26°C and lows of 18 to 19°C, cooler than Hong Kong's June highs of around 31°C, so a light layer comes in handy.
- Humidity:Often around 80%, similar to Hong Kong, so it feels warmer than the thermometer says.
- Crowds and prices:Far fewer tourists than cherry blossom or autumn foliage season, which often means easier bookings and better hotel deals.
It rains less than you'd think. Plenty of days are cloudy but dry, and many of the sights below look better with wet leaves and glossy petals. If a day does turn properly wet, the Tokyo National Museum is a solid indoor fallback.
Klook Tip: Tuen Ng Festival falls on Wednesday 9 June 2027. Taking Thursday and Friday as annual leave gives you five days off in a row, ending on Sunday 13 June, so book flights and hotels early.
Hakusan Shrine hydrangea festival: petal power in the city

The Hakusan Shrine hydrangea festival (officially the Bunkyo Hydrangea Festival, or Ajisai Matsuri) is the easiest way to see Tokyo hydrangeas without leaving the city. More than 3,000 plants fill the shrine grounds and neighbouring Hakusan Park, and entry is free. In 2026 it ran between 6 and 14 June, and it tends to follow a similar early-to-mid June window. It's a classic early-summer ritual across Japan.
Go early for fewer people and softer light. The shrine hill is packed with ajisai (hydrangeas) in blue, pink and purple. During the festival you'll find snack stalls, small performances and weekend events. An umbrella is handy here, since the hill paths can be damp.
Address: Hakusan Shrine, 5-31-26 Hakusan, Bunkyo City, Tokyo
- How to get there:2-minute walk from Hakusan Station (Toei Mita Line, Exit A3)
Meiji Jingu iris garden: a purple patch in Harajuku
Meiji Jingu Shrine
The Inner Garden inside Meiji Jingu Shrine is where the Meiji Jingu iris garden blooms each June, with about 1,500 plants across 150 varieties. Entry to the Inner Garden is JPY 500 (about HKD 25), and the shrine grounds themselves are free to walk. Take the shaded forest path from the main torii gate first, and don't miss Kiyomasa's Well while you're there.
The shrine doesn't publish fixed bloom dates, so check its news page before making a special trip. Weekday mornings are calmer, and the iris field is much quieter in light rain.
Address: 1-1 Yoyogikamizonocho, Shibuya City, Tokyo
- How to get there:Harajuku Station (JR Yamanote Line) or Meiji-jingumae Station
Horikiri Iris Garden: free entry, Edo-era fame
If you want irises without the Harajuku crowds, head east to Horikiri Iris Garden in Katsushika. This one has been famous since the Edo period, and it even appears in Hiroshige's woodblock prints. Entry is free, and the garden sits along a river with winding paths and small bridges.
The Katsushika Iris Festival here ran from late May to mid-June in 2026. It's a good pick for a slow morning, then you can wander the local streets nearby for lunch.
Address: Horikiri Shobuen, 2-19-1 Horikiri, Katsushika City, Tokyo
- How to get there:About 10 minutes on foot from Horikiri-shobuen Station (Keisei Main Line)
Kamakura hydrangeas: the big blue day trip
No list of Tokyo in June highlights is complete without Kamakura hydrangeas. Meigetsu-in, nicknamed the hydrangea temple, is famous for pale blue hydrangeas along its stone steps. Hase-dera has a hillside hydrangea path with sea views, and it charges a small extra fee in season. Kamakura is about an hour from Tokyo by train.
Go on a weekday morning, because the queues build fast. Meigetsu-in is worth the queue if you do end up waiting, and it's an easy day trip, so you can be back in Tokyo for dinner. A small bag makes it easier, and our travel light Tokyo guide has packing tips.
Klook Tip: Arrive at Meigetsu-in early, since queues build by mid-morning in peak hydrangea season.
Address: Meigetsu-in, 189 Yamanouchi, Kamakura, Kanagawa
- How to get there:About 10 minutes on foot from Kita-Kamakura Station (JR Yokosuka Line). Hase-dera is a 5-minute walk from Hase Station (Enoden Line).
Hakone hydrangea train: a ride through the blooms
Hakone Kamakura Pass
The Hakone hydrangea train is as scenic as it sounds. The Hakone Tozan Railway zigzags up the mountain between Hakone-Yumoto and Gora, and the flowers grow so close to the tracks they almost touch the windows. Blooms usually appear in mid-June, and the peak creeps uphill through mid-July.
In 2026 there was also an evening Night Hydrangea Train, a reserved-seat ride with a seat fee of JPY 500 (about HKD 25) on top of the fare. The lit-up flowers glowed from 6.30pm to 10pm. Check the railway's site for 2027 details.
Address: Hakone-Yumoto Station, Hakone, Kanagawa
- How to get there:About 1.5 hours from Shinjuku by Odakyu Romancecar
Firefly viewing in Tokyo: a glow-up at Chinzanso
Firefly viewing in Tokyo is rarer than you'd expect, but Hotel Chinzanso in Bunkyo has hosted firefly nights since 1954. Its garden fills with hotaru (fireflies) from mid-May through June, and the glow near Benkei Bridge is the highlight. Garden access is tied to the hotel's firefly events and dinner buffet, so check the details and reserve ahead.
Yomiuriland's flower park also runs evening firefly nights in the same season. Dates shift a little with the weather every year. Keep your voice low and skip the flash, because the fireflies are shy.
Address: Hotel Chinzanso Tokyo, 2-10-8 Sekiguchi, Bunkyo City, Tokyo
- How to get there:About 10 minutes on foot from Edogawabashi Station (Exit 1A, Tokyo Metro Yurakucho Line)
Sanno Matsuri at Hie Shrine: Edo's big June party
Sanno Matsuri is the big June festival at Hie Shrine, counted among Edo's three great festivals. It's held in mid-June. The full grand procession (Jinko-sai), with hundreds of people in Edo-period dress, only runs in even-numbered years. 2026 was a main year, with the procession on 12 June.
That means 2027 will be the smaller version, centred on rituals at the shrine rather than a citywide parade. It's still worth a visit for the quiet shrine grounds and seasonal rituals, and the full parade returns in 2028.
Klook Tip: The 2027 dates haven't been announced yet, so check Hie Shrine's official site before you lock in your plans.
Address: Hie Shrine, 2-10-5 Nagatacho, Chiyoda City, Tokyo
- How to get there:A few minutes on foot from Tameike-sanno Station (Ginza and Namboku lines)
