Have you ever seen photos of a field covered in tiny blue flowers and wondered where in Japan it is?
There is a good chance you were looking at Hitachi Seaside Park in Ibaraki Prefecture.
Located about 85 minutes from Tokyo by limited express train, Hitachi Seaside Park is one of Japan’s most spectacular places to see seasonal flowers. It is especially famous for its nemophila in spring and red kochia in autumn, but there is much more to see throughout the year.
I live in Tokyo, and I think Hitachi Seaside Park makes a particularly interesting day trip if you want to get away from the usual Tokyo sightseeing spots.
In this guide, I’ll explain the best time to visit, how to get there from Tokyo, how to get around the huge park, admission fees, and how the JR TOKYO Wide Pass can fit into your trip.

Why Visit Hitachi Seaside Park?
Hitachi Seaside Park is a huge seaside park in Hitachinaka, Ibaraki Prefecture.
The park is famous for its enormous flower fields, especially the Miharashi no Oka (Miharashi Hill) area.
In spring, millions of blue nemophila flowers cover the hill. In autumn, thousands of kochia plants turn bright red.
But don’t think of Hitachi Seaside Park as a place you can only visit in April or October.
Flowers bloom throughout the year, including tulips, roses, lavender, sunflowers, cosmos, plum blossoms, and winter ice tulips.
There is also a cycling course, a sightseeing train, restaurants, picnic areas, and an amusement park.
So even if you are not visiting specifically for the famous nemophila or kochia, there are plenty of reasons to spend a day here.
When Is the Best Time to Visit Hitachi Seaside Park?
The best time depends on what you want to see.
Spring: Nemophila and Tulips
Spring is probably the most famous season at Hitachi Seaside Park.
Nemophila usually blooms from mid-April to early May.
The flowers cover Miharashi Hill in blue, creating a spectacular view where the flowers, sky, and sea seem to blend together.
The park has around 5.3 million nemophila plants, making the flower field enormous.
April is also a great time to see tulips, which usually bloom from mid- to late April.
If you visit in spring, you may be able to enjoy several different types of flowers during the same trip.
Summer: Sunflowers, Zinnias and Green Kochia
Summer is much hotter, but the park doesn’t stop blooming.
Zinnias generally bloom from late July to late August, while sunflowers are usually at their best around mid-August.
You can also see green kochia from around mid-August through late September.
If you want to see kochia without the autumn crowds and red foliage, summer is an interesting alternative.
Autumn: Red Kochia and Cosmos
Autumn is another extremely popular season.
Kochia starts changing color in early October, and the plants usually become beautifully red around mid-October.
The sight of thousands of round red kochia plants covering Miharashi Hill is one of the park’s most recognizable views.
Cosmos also bloom around this time, creating a colorful contrast with the kochia.
If you are interested in autumn foliage rather than traditional Japanese maple leaves, Hitachi Seaside Park is worth considering.
Winter and Early Spring: Ice Tulips and Plum Blossoms
The park is much quieter during the colder months, but there are still seasonal attractions.
Ice tulips generally bloom from late December to early January, while plum blossoms can be seen from late January into March.
This can be a good option if you want to experience Hitachi Seaside Park without visiting during the two busiest flower seasons.
Hitachi Seaside Park Flower Calendar
Here is a quick overview of the main seasonal flowers.
- Early March to mid-March: Early-blooming daffodils
- Late March to mid-April: Daffodils
- Mid-April to late April: Tulips
- Mid-April to early May: Nemophila
- Mid-May to early June: Roses
- Late June to early July: Lavender and hydrangeas
- Late July to late August: Zinnias
- Mid-August: Sunflowers
- Mid-August to late September: Green kochia
- Late August to early October: Yellow cosmos
- Early October to late October: Cosmos
- Mid-October: Red kochia
- Late December to early January: Ice tulips
- Late January to mid-March: Plum blossoms
Flowering times depend on weather, so always check the official flower information before your trip.
The Famous Nemophila at Miharashi Hill
If you have seen photos of Hitachi Seaside Park online, there is a good chance they show Miharashi Hill covered in blue nemophila.
The combination of blue flowers, blue sky, and the Pacific Ocean in the distance creates an almost surreal landscape.
The nemophila season is also one of the busiest times of the year.
If you want to take photos without quite as many people, visiting early in the morning on a weekday is worth considering.
During the peak season, the park may also open earlier than its regular opening time, so check the official calendar before you visit.
Red Kochia in Autumn
The autumn version of Miharashi Hill looks completely different.
The green kochia gradually changes color before becoming bright red, usually around mid-October.
Cosmos and other autumn flowers grow around the hill, making this one of the most colorful times to visit.
If you are deciding between spring nemophila and autumn kochia, remember that they are completely different experiences.
Spring is dominated by an enormous blue landscape, while autumn has a warmer mix of red, pink, yellow, and green.
How to Get to Hitachi Seaside Park from Tokyo
The easiest way for most international visitors is to travel by train.
Step 1: Tokyo to Katsuta Station
From Tokyo Station, take a JR limited express train such as the Hitachi or Tokiwa to Katsuta Station.
The journey takes approximately 85 minutes.
Step 2: Katsuta Station to Hitachi Seaside Park
From the East Exit of Katsuta Station, go to bus stop No. 2.
Take an Ibaraki Kotsu bus bound for the park.
The bus ride takes approximately 15 minutes.
A taxi from Katsuta Station also takes around 15 minutes.
Tokyo → Katsuta → Hitachi Seaside Park
The basic route is:
Tokyo Station
↓ JR Limited Express Hitachi or Tokiwa
Katsuta Station
↓ Ibaraki Kotsu Bus
Hitachi Seaside Park
This is the route I recommend for travelers staying in Tokyo who do not have a rental car.
Can You Use the JR TOKYO Wide Pass?
Yes, the JR TOKYO Wide Pass can be useful for a trip to Hitachi Seaside Park if you are planning to explore other destinations in the Tokyo and surrounding area during the same three-day period.
The pass is available to travelers holding a non-Japanese passport and is valid for three consecutive days.
As of 2026, the price is:
- Adult: ¥16,000
- Child: ¥8,000
The pass covers eligible JR East trains within its designated area, including limited express and other JR East services.
This means it can be useful when Hitachi Seaside Park is just one part of a larger three-day itinerary.
For example, you could combine your Hitachi Seaside Park trip with other destinations covered by the pass rather than buying it specifically for this one day trip.
Important: Don’t Buy the Pass Just for Hitachi Seaside Park
This is an important point.
If you are only making a round trip from Tokyo to Hitachinaka, the JR TOKYO Wide Pass may not necessarily save you money.
The pass costs ¥16,000 and is valid for three consecutive days, so its value depends on how much other train travel you do during those three days.
Before buying it, compare your planned train journeys with the current pass price.
If you are already planning several trips around the Tokyo and surrounding area, however, the pass can be a convenient option.
Also remember that the bus from Katsuta Station to Hitachi Seaside Park is not included in the JR pass, so you will need to pay separately for the local bus.
How to Get Around Hitachi Seaside Park
Don’t underestimate the size of this park!
Hitachi Seaside Park is huge, and walking between different areas can take much longer than you might expect.
You have several options.
Walk
Walking is free and gives you the freedom to stop wherever you want.
However, comfortable shoes are essential.
If you want to see several areas of the park in one day, walking the entire park can be tiring.
Take the Seaside Train
The Seaside Train is a sightseeing train that circulates around the park.
A one-day pass costs ¥600 for visitors aged three and older.
One complete circuit takes approximately 40 minutes, and the train stops at several locations around the park.
It is especially useful when you want to move between distant areas without walking the entire way.
Rent a Bicycle
Cycling is another good way to explore the park.
The park has a dedicated cycling course and rental bicycles, including electric-assisted bicycles.
For travelers who enjoy cycling, this can be one of the best ways to see more of the park in a single day.
Hitachi Seaside Park Admission Fees
Regular admission is currently:
- Adults (high school age and older): ¥450
- Seniors aged 65 and older: ¥210
- Junior high school students and younger: Free
During the major nemophila and kochia seasons, a ¥350 seasonal surcharge is added.
For example, during the 2026 spring peak season, adult admission was ¥800 including the seasonal surcharge.
The exact seasonal dates and surcharge can change, so check the official website before your visit.

What Else Can You Do at Hitachi Seaside Park?
There is more to the park than flowers.
Pleasure Garden
The park has an amusement park area called Pleasure Garden, with rides and attractions for families.
If you are traveling with children, you can easily spend much longer here than you might expect.
Cycling
The park has a dedicated cycling course, making it a nice change from sightseeing on foot.
Picnicking
There are plenty of open spaces where you can relax and enjoy a picnic.
During busy flower seasons, bringing food from outside can also be a practical option if restaurants and food stands are crowded.
Restaurants and Cafes
There are several places to eat inside the park, including restaurants and cafes.
During the major spring and autumn sightseeing seasons, additional food stalls may also be available.
Because the park is large, it is a good idea to think about where you want to eat before you get hungry!
Tips for Visiting Hitachi Seaside Park
1. Go Early During the Peak Flower Seasons
Nemophila and red kochia are extremely popular.
If you visit during peak season, arriving early can make your experience much more comfortable.
2. Check the Flowering Conditions Before You Go
Don’t rely only on a fixed calendar.
Flowers are affected by weather, temperature, and other conditions.
The official website regularly provides current flower information, so check it shortly before your trip.
3. Wear Comfortable Shoes
You will probably walk much more than you expect.
Even if you use the Seaside Train, there is still plenty of walking involved.
4. Allow at Least Half a Day
If your main purpose is to see Miharashi Hill, you can visit the park in a few hours.
But if you want to explore other areas, cycle, eat, or enjoy the amusement park, I recommend allowing most of the day.
5. Bring Sun Protection
Much of the park is open and exposed to the sun.
A hat, sunscreen, and water are especially important during spring and summer.
6. Check for Special Opening Hours
During major flower seasons and special events, the park may open earlier or have different operating arrangements.
Always check the official website before you leave Tokyo.
Is Hitachi Seaside Park Worth Visiting from Tokyo?
Staying in Tokyo? Check hotels near Tokyo Station for an easier early-morning start.
If you love flowers, photography, cycling, or simply want to experience a different side of Japan outside the major tourist cities, Hitachi Seaside Park is a great day-trip destination to consider.
It is also a good choice if you have already visited the classic Tokyo attractions and want to see somewhere that feels less urban.
The biggest attraction is obviously the spectacular flower scenery.
But what I personally like about Hitachi Seaside Park is that you don’t have to visit only during the famous nemophila or kochia seasons.
There is something happening throughout much of the year.
If you are planning a three-day regional trip, the JR TOKYO Wide Pass is also worth checking, especially if you plan to visit several destinations covered by the pass.
Love Seasonal Flowers?
If you’re looking for another spectacular flower destination that you can visit from Tokyo, Ashikaga Flower Park in Tochigi is another great option.
It is especially famous for its enormous wisteria displays in spring, but flowers and seasonal illuminations can be enjoyed throughout the year.

Final Thoughts
Hitachi Seaside Park is much more than a famous Instagram photo spot.
In spring, you can walk through a sea of blue nemophila.
In summer, the park becomes a colorful garden of sunflowers, zinnias, and green kochia.
In autumn, the kochia turns brilliant red.
And even in winter, seasonal flowers and quieter landscapes make the park worth considering.
From Tokyo, the journey is relatively straightforward: take a JR limited express to Katsuta Station and then a local bus to the park.
Just remember that the park is enormous, so don’t try to squeeze everything into a short visit.
Choose the season you like best, wear comfortable shoes, and give yourself enough time to enjoy the park at your own pace.
For me, that’s part of the appeal of Hitachi Seaside Park: it feels like a completely different world from central Tokyo, but you can still visit it as a day trip.
