Enjoy the Bay and Lawns at Agawa Hōsenguri Seaside Park
Agawa Hōsenguri Seaside Park (Agawa Hōsenguri Kaihin Kōen) in Hōhoku-chō, Shimonoseki City, Yamaguchi Prefecture, is a seaside park where you can move between the beach inside the bay and a spacious lawn.
With clear water and a bay whose terrain helps keep the waves calm, it is a swimming beach that has long been cherished in the Agawa area.
Check the Shape of the Bay and Conditions Offshore
Even when the surface looks calm, water conditions change with the wind, tides, weather, and boat traffic.
When you arrive, do not head straight to the water. Check the designated swimming area, warning signs, and information about supervision and management to confirm where you may go that day.
Even when playing with small children, do not assume that the word “calm” guarantees safety. An adult should always remain within arm’s reach.
Use the Beach and Lawn for Different Purposes
The beach lets you stay close to the sea, while the lawn makes it easier to rest and organize your belongings, so you can plan separate areas for play and breaks.
The lawn is also a shared space. Do not block walkways with tents or mats, and remain within the areas designated by management.
Wet feet can slip when running on the grass. After leaving the sea, rinse off water and sand and walk across the lawn.
Understand the Role of Each Area
Switching activities according to the area of the park helps keep the movement of people and belongings from overlapping.
| Area | Suitable Activity | What to Check |
|---|---|---|
| Beach | Watch the sea and waves | Check swimming signs |
| Water’s edge | Play in shallow water | Stay close to children |
| Lawn | Take a break | Keep walkways clear |
| Management facilities | Register and confirm details | Prioritize on-site guidance |

Check the Swimming Season and Fees
At a seasonal swimming beach, being able to enter the sand and being able to swim in a managed environment are not the same thing.
The swimming beach operates seasonally. Confirm that it is open on the day you plan to visit.
Prioritize Same-Day Guidance Even During the Open Season
Even during the season, swimming conditions may change because of the weather, waves, or management circumstances.
Read the visitor information and signs on the day. If swimming is not allowed, switch to a plan that includes resting on the lawn or enjoying the coastal scenery.
Outside the open season, supervision and facility operations differ, so do not assume summer conditions apply. Plan to enjoy the area without entering the sea.
Environmental Maintenance Contribution and Shower Fee
The environmental maintenance contribution, which serves as the summer swimming fee, is 600 yen for high school students and older visitors and 300 yen for elementary and junior high school students.
Coin-operated showers cost 200 yen. If you plan to use one, bringing coins will make the process easier.
Pay the required fees according to the guidance provided to maintain the facilities and environment, and prioritize on-site signs if prices have been revised.
Use the Table to Avoid Missing Any Conditions
Here is a brief summary of swimming and facility categories.
| Item | Fee or Condition | What to Reconfirm |
|---|---|---|
| Open season | Seasonal operation | Opening status on your visit date |
| High school students and older | 600 yen | On-site fee |
| Elementary and junior high school students | 300 yen | Age category |
| Shower | 200 yen | Hours of use |

Decide on Safe Areas and Responsibilities Before Entering the Sea
Even in a calm bay, the right way to play changes with each visitor’s experience and physical condition, as well as the wind and heat.
First Check the Swimming Area and Whether Supervision Is Available
If buoys, flags, announcements from management, or posted notices indicate a swimming area, follow those boundaries and instructions.
Do not make swimming farther offshore or leaving the designated area your goal. Stay at a depth and distance from which you can return to shore.
Inflatable floats can also be carried by the wind, so repeatedly check your distance from shore.
Clearly Assign Responsibility for Watching Children
When several adults are present, do not assume someone else is watching. State clearly who is responsible and when that person will be relieved.
Choose children’s life jackets and water-play equipment that fit their size, and check for looseness after putting them on.
When the supervising adult returns to shore for a break or to change clothes, clearly hand over responsibility to someone remaining in the water.
Notice Heat and Changes in Physical Condition Early
Even when the sea breeze makes the heat less noticeable, strong sunlight and physical activity cause fluid loss.
Drink before you feel thirsty, rest in the shade or on the lawn, and do not allow anyone with a headache, nausea, or severe fatigue to swim.

Plan Breaks Around the Restrooms, Showers, and Lawn
Restrooms and showers are available, so checking their locations when you arrive can reduce confusion when it is time to leave.
Facility hours and conditions may change with the season. Bring what you need instead of relying entirely on the facilities.
Keep Changes of Clothes and Belongings Compact
Separate valuables, dry clothes, and a bag for wet items, and minimize what you take onto the beach.
Do not leave belongings in walkways or in front of facilities, and secure bags and towels so the wind cannot carry them away.
Avoiding a route that takes you back across the beach after showering helps keep sand out of your clothes and vehicle.
Use the Lawn for Resting and Supervision
On the lawn, you can dry off, drink water, and keep watch over both sea conditions and the people with you.
If playing with a ball or taking part in similar activities, check your distance from other visitors, tents, and the road, and refrain when the area is crowded.
Leave No Trash or Damage in the Coastal Environment
Do not leave food wrappers, empty sunscreen containers, or broken recreational equipment on the beach or lawn. Follow the facility’s sorting instructions or take them home.
Shells and items washed ashore may include dangerous objects. Do not touch them with bare hands, and report any hazards you find to management.
Calculate Camping Fees Separately from Swimming Fees
Camping is available at Agawa Hōsenguri Seaside Park, but paying only the tent fee does not cover all use of the seaside park.
In addition to the tent fee, campers must pay the seaside park use fee for each person.
1 Brought-in Tent for 1 Night Costs 3,000 Yen
The fee for 1 brought-in tent for 1 night is 3,000 yen, and camping is available year-round.
In summer, add 600 yen for each high school student or older visitor and 300 yen for each elementary or junior high school student, calculating the number of people and tents separately.
Published information may not cover reservations, reception hours, open flames, vehicles, lights-out rules, and other operating procedures, so confirm these with the facility before your visit.
Prioritize Preparation for Coastal Wind and Tides
Tents are exposed to the wind, and the weather may change at night or while you are away.
Follow management guidance for where and how to secure your tent and when to evacuate, and be prepared to cancel your stay when strong winds or severe weather are forecast.
Organize the Fee Structure
Camping costs depend on both the number of tents and the number of people.
| Fee | Unit | What to Confirm |
|---|---|---|
| Tent fee | 1 tent for 1 night | 3,000 yen |
| High school students and older | 1 person | 600 yen |
| Elementary and junior high school students | 1 person | 300 yen |
| Facility use | Per use | On-site signs |
Because fees and operations may change, prepare not only cash but also contact information and an alternative place to stay.
Plan Access from Agawa Station and Tsunoshima Bridge
When arriving by public transportation, consider the walking section. When driving, account separately for seasonal parking fees and congestion.
About a 10-Minute Walk from JR Agawa Station
It is approximately a 10-minute walk from JR Agawa Station on the San’in Main Line.
Check train frequency and your return departure time first, and allow time to walk with wet clothing or large belongings.
Check sidewalk and road conditions, and do not force yourself to walk at night or in bad weather.
Drivers Should Check Parking Conditions During Swimming Season
Parking is available and is subject to a fee during swimming season.
If the lot is full, do not park on the road or vacant land. Follow on-site directions, and do not plan your arrival based only on the driving time from Tsunoshima Bridge.
Combine Your Visit with Tsunoshima Sightseeing
Agawa Hōsenguri Seaside Park is approximately 5 minutes by car from Tsunoshima Bridge, but viewing the bridge, parking, and enjoying the sea each require separate time.
Anyone driving after swimming should rest and change clothes first, and avoid rushing onward when fatigued or drowsy from strong sunlight.
Decide in Advance What to Do During a Coastal Disaster
Do Not Judge Evacuation Locations by the Park Alone
If you feel an earthquake near the coast or receive tsunami information, do not return toward the sea to collect belongings. Follow instructions from the local government and on-site announcements and move to higher ground.
Whether an evacuation shelter can be used depends on the type of disaster, so do not assume that a listed park name means the shelter handles every kind of disaster.
Before your visit, check the disaster-prevention map and evacuation route, and decide how your group will reunite.
Summary of Agawa Hōsenguri Seaside Park
Agawa Hōsenguri Seaside Park is a place where you can plan your time by the sea using its calm bay, beach, and lawn for different purposes.
Check the opening status and fees, then plan the swimming area, child supervision, heat precautions, and route to the facilities in advance to prioritize safety while enjoying your visit.
For camping, calculate tent fees separately from per-person use fees, and plan the return journey together with travel to Agawa Station or the Tsunoshima area, event dates, and actions to take during a disaster.
