【A Must-See for Train and Bus Travelers】 The "Minato Line + Shuttle Bus" Route to Avoid Long Lines at the Station

Is the bus wait at Katsuta Station really 60 minutes!? Are there any alternatives?
There is a direct bus from JR Katsuta Station to the park, but during the Golden Week holiday, there can be long lines. It's common to wait 30 to 60 minutes from when you line up at the bus stop until you board. Additionally, there is a possibility of getting caught in traffic once you're on the bus.
Direct Bus Information from Katsuta Station
- Travel Time: Usually 15 minutes (over 30 minutes during traffic jams)
- Fare: 450 yen one way
- Peak Crowds: 9:00 AM to 11:00 AM
Benefits of Hitachinaka Seaside Railway + Free Shuttle Bus
Here is a recommended route from the locals.
- Take the "Hitachinaka Seaside Railway (Minato Line)" from JR Katsuta Station.
- Get off at the final stop, "Ajigaura Station" (approximately 20 minutes).
- Take a free shuttle bus from the station to the "Umihamako" entrance of the park (approximately 10 minutes).
- If you enter from the seaside entrance, it takes about a 10-minute walk to reach the scenic hill.
Three Benefits of This Route
- Avoid the bus queue at Katsuta Station completely!
- Enjoy the charm of traveling on the local Minato Line.
- The Umihamiguchi Entrance is the closest access point to "Miharashi Hill."
The fare for the Minato Line is 330 yen one way, but considering that you'll have zero stress from waiting times, it's well worth it.
Four Essential Rules for a Comfortable Visit to the Park
The Hitachi Seaside Park is even more expansive than you might imagine! Covering an area equivalent to about 41 Tokyo Domes, it would be quite exhausting to try to walk around the entire park.
1. As soon as you enter, rent a bicycle!

Bicycle Rental Information
- Fees: 600 yen for 3 hours, with an additional 100 yen for every extra 30 minutes. A one-day pass is available for 800 yen (excluding peak seasons).
- Rental Locations: Cycle centers at the West Exit, Central, South Exit, and Seaside Exit.
- Number of parking spaces: Approximately 1,400 spaces
- Recommended Highlight: The cycling course within the park (approximately 13 km) is free of traffic signals and cars, providing a refreshing experience!
If you have a bicycle, you can efficiently move between the nemophila fields, tulip gardens, and the Ferris wheel area, making the most of your time during your visit. Please note that during the Golden Week, bike rentals may run out by the morning, so it's a good tip to rent one as soon as you enter the park.
You can also bring your own bicycle.
2. Utilizing the Seaside Train (Loop Bus)
For those who are not comfortable with cycling, seniors, or families with small children, we recommend the "Seaside Train" that circles around the park.
Seaside Train Information
- Fee: 500 yen per visit
- Route: A loop around major spots including the West Exit, Tsubasa Gate, Mihara Hill, and the Sand Dune Area.
- Duration: Approximately 40 minutes for one round.
Choosing between renting a bicycle and taking the train depends on your physical condition and the weather. On rainy days or when it's windy, the train is a more comfortable option.
3. After leaving the park at 10:30, it's time for lunch at the market!
There are restaurants and cafes within the park, but during busy times, the wait can be quite long. You have two options.
Option A: Enjoy gourmet food in the park.
- Nemophila Curry (Limited Time Only)
- Blue Soft Serve Ice Cream "Nemophila Blue Soft"
- Dining at a seaside restaurant
Option B: Depart the park around 10:30 and head to Nakaminato Fish Market.
- A short 15-minute drive away.
- Enjoy a wide variety of fresh seafood bowls and sashimi!
- It gets really crowded after 11:30, so it's better to arrive early!
- You can avoid traffic on your way back.
As a local, I recommend the following route: enter the park early in the morning, enjoy the beautiful nemophila flowers, exit by 10:30, have lunch at the fish market, and then relax at a hot spring.

"Outfits and Essentials that Combine Style and Practicality"
Shoes and Cold Weather Preparation
The park is quite spacious and includes some hills to climb and descend. Comfortable shoes like sneakers are a must. Additionally, even in spring, there can be windy days coming from the sea, so having a light jacket to throw on will make you feel more at ease.
Seasonal Advice
- Mid-April: The maximum temperature ranges from 15 to 18°C, with morning and evening temperatures dropping below 10°C. A light down jacket or windbreaker is essential!
- Late April to early May: The maximum temperature is around 20°C. A long-sleeved shirt with a cardigan is perfect!
The coastal area can be windier and cooler than you might expect, so it's a good idea to bring an extra layer with you.
Tips for Photography
Three Tips for Capturing the Beauty of Nemophila Flowers
- Time: The soft natural light from 8 AM to 10 AM is the best. In the afternoon, it tends to become backlit.
- Composition: By capturing a large portion of the sky, a beautiful gradient of blue tones is created.
- Subject: Holding a Nemophila Blue Soft Serve Ice Cream for a Perfect Instagram Shot!
Camera Settings Tips
- Capture the sky and nemophila together with a wide-angle lens (24mm or less).
- Set the aperture value between F8 and F11 for a deep focus effect.
- The white balance is set to "Sunny," emphasizing the blue tones.
When taking photos, please refrain from stepping into the flower beds and use the designated pathways for your shots. Let's respect the rules and preserve the beautiful scenery for future generations!
A Handy Packing List
- Sunscreen and hats (for sunny days)
- Beverages (Please note that vending machines in the park may run out of stock during busy times.)
- Leisure sheet (for picnics in the grassy area)
- Wet wipes and disinfectant spray
- Mobile battery (You'll run out of power if you take too many photos!)
- Plastic bags (for taking your trash home)
Avoid traffic on your way back! Enjoy a smooth exit time.
From 1 PM to 3 PM, both the parking lot exit and the bus stop can get extremely crowded. We recommend leaving at "10:30 AM" or "after 4 PM" for a smoother experience.
For those traveling by car, we provide detailed information on 👉[ traffic avoidance routes and parking strategies ].
We recommend staying overnight.
Enjoy a Full Experience with Pre- and Post-Stay Plans!
If you want to ensure early entry, we recommend staying overnight.
If you're planning a day trip from Tokyo, you often end up arriving between 9 and 10 AM. However, if you stay overnight in Ibaraki Prefecture the day before, you can easily make it in time for the early opening at 7 AM.
Recommended Accommodation Areas
- Within Hitachinaka City: A 10-minute drive to the park.
- Oarai Town: Close to the sea and home to many hot spring inns.
- Mito City: The prefectural capital with plenty of accommodation options.
At my guesthouse, many visitors choose to stay the night before during the nemophila season. This allows for an ideal schedule of waking up at 5 AM, departing at 6 AM, and entering the park by 7 AM.
