Highlights of Awashima Marine Park

Awashima Marine Park is on Awashima Island, reached by boat from the mainland, where you can enjoy the aquarium, the Frog House, and seaside views all in one visit.

Aquarium Highlights

At the Awashima Marine Park aquarium, paying attention to the creatures' body shapes and how they swim lets you feel their connection to Suruga Bay right in front of you.

One of Japan's Largest Frog Houses

The Frog House is said to have one of the largest numbers of frog species on display in Japan, letting you compare how more than 50 species from Japan and around the world hide and their body colors.

Getting There and Regular Boat

By public transport, take a Tokai Bus bound for Osezaki/Nagahama from the South Exit of Numazu Station, then cross to Awashima from the pier by regular boat in about 3 minutes one way.

Check Your Return Boat First

Since you cross to the island by boat, check the return boat and boarding point you will use as soon as you arrive, then plan your time on the island.

Watch for Trail Closures

The shrine mountain path and the trail on the back side of the island may be closed due to weather such as heavy rain, so walk only in the open areas and follow no-entry signs.

Prepare for Sea Breezes and Footing

On the boat and on the island, prepare for sea breezes, sun, and rain with non-slip, well-worn walking shoes and a jacket to adjust your body temperature.

Your Awashima Trip Begins with the Boat Ride

Check the Day’s Conditions on the Mainland

On the day you visit Awashima, first check the operating status of Awashima Marine Park and the boat service.

Because the island is reached by boat from the mainland, unlike a sightseeing spot on land, your plan must account for the departure time and the return boat.

Information may change because of strong winds, rain, or facility maintenance, so it is important to update the schedule you made the day before with the latest information on the day of your visit.

Decide How You Will Return as Soon as You Arrive

Once you reach the island, confirm the return boat you will take and its boarding point first.

Rather than checking the time after becoming absorbed in the aquarium exhibits, you can move around more calmly if everyone shares a target time for leaving.

With family or other companions, deciding which exhibits to prioritize and where to wait if the weather worsens will help you make better use of your limited time on the island.

Leave Extra Time for Each Form of Transportation

If you are traveling by public transportation, allow plenty of time for the connection between the bus from the Numazu Station area and the boat.

If you are driving, do not treat parking and boarding as one continuous step; include time to organize your belongings and use the restroom.

You can check the location and route, but road and public transportation travel times can change with congestion, so avoiding an overly packed schedule will help keep your trip safe.

By public transportation, you can take a Tokai Bus from the south exit of Numazu Station toward Osezaki or Nagahama, then cross to Awashima from the pier by scheduled boat in about 3 minutes each way.

Explore the Aquarium’s Connection to Suruga Bay

Look Beyond the Animals’ Names

At the aquarium, do more than identify the animals on display: notice their body shapes, how they swim, and where they hide.

Thinking back and forth between the sea in front of you and the exhibits makes the environment of Suruga Bay feel more immediate.

Instead of reading every information panel at once, choose one species that interests you and check its characteristics and habitat to create a focus for your observations.

Separate Observation Time from Photography

At a tank, a good approach is to spend the first 1 minute observing without looking at a screen, then take the photos you need.

Be mindful of reflections and the movement of other visitors, and do not block the passageway.

Follow the signs on site regarding whether flash and other photography methods are allowed, and keep enough distance to avoid burdening the animals or people around you.

Notice the Different Habitats in the Frog House

The Frog House Has One of Japan’s Largest Selections of Frog Species

The Frog House at Awashima Marine Park is said to have one of the largest selections of frog species on display in Japan.

More than 50 species, ranging from Japanese frogs to frogs from around the world, are exhibited here, allowing you to compare how they hide and how their body colors differ.

Study the Exhibit Environment Before Looking for the Frogs

In the Frog House, instead of trying to find each frog immediately, first look at differences in the exhibit environments, such as the water, leaves, branches, and ground.

When you look for the way their colors and postures blend into the background, the hiding behavior itself becomes part of the observation.

If a frog is hard to see, never tap on the tank; wait while quietly changing your viewing angle.

Choose One Observation Question with Children

If you are visiting with children, narrowing the activity to one question, such as “Where is it hiding?” or “What do its fingertips look like?” can help them concentrate.

Do not rush to find the right answer; put the features you notice into words and share them.

Watch your footing and keep a safe distance from the display cases. In crowded areas, take short turns so people behind you can also see.

Respect the Animals’ Pace at the Outdoor Exhibits

Include Quiet Periods in Your Observation

Outdoor animals may move differently depending on the weather, temperature, and how they are feeling that day.

Rather than expecting only active behavior, notice animals at rest and listen to the keepers’ guidance so you can observe without trying to stimulate them.

Events and exhibits may change, so do not assume that a particular program will be available; use the day’s posted information as your guide.

Be Considerate with Noise and Distance

Loud voices and sudden movements can affect not only other visitors but also the animals’ calm behavior.

Respect fences and no-entry signs, and do not reach out or show food to the animals.

Because it is easy to miss a step behind you while concentrating on a photo, check where you are standing before raising your camera.

Walk the Seaside and Island Paths According to Conditions

Check Your Footing Before the View

The sea and the view toward the opposite shore can draw your attention on Awashima, but outdoors you should check slopes, wet surfaces, and steps first.

Even in clear weather, sea breezes can blow away hats or belongings, so a bag that leaves both hands free is useful.

Paths leading toward the mountain side or the back of the island may have changing access conditions because of weather or maintenance, so follow the on-site entry signs.

Compare the Scenery from the Same Place

When looking across the open sea, observe the waves at your feet, the outlines of the rocks, and the movement of boats in order, rather than looking only at the distant view.

Clouds and light can change the colors even in the same place, so stopping for a few minutes instead of rushing on lets you experience Awashima’s distinctive pace.

However, do not linger in a passageway; choose a safe place where it is easy to enjoy the view.

Have an Alternative Plan for Closures or Detours

If a path you planned to use is closed, do not push ahead; switch to another look around the aquarium or take a break.

Closures are in place for safety, so never climb over a fence or try to go around via the shore.

Instead of making it your goal to walk everywhere, plan to enjoy the areas that are open that day with care.

Place What to Observe What to Keep in Mind
Aquarium Swimming styles and body shapes Do not block the passageway
Frog House Hiding behavior and habitat Do not tap the exhibits
Outdoor Exhibits Behavior, including resting Respect fences and distance
Seaside and Paths Changes in waves, rocks, and light Check your footing and entry signs

Improve Your Visit with the Right Clothing and Breaks

Prepare for Both Sea Breezes and Sunlight

On the boat and around the island, you need to be prepared for sunlight, sea breezes, and rain.

Choose familiar, slip-resistant shoes and bring an outer layer that lets you adjust your body temperature.

In hot weather, remember a drink and hat; in cold weather, consider wind-resistant clothing. Do not rely only on the season’s name—dress for the day’s forecast.

Take a Seat Before You Become Tired

Viewing exhibits continuously can reduce your concentration because there is so much information to absorb.

After each area, take a short break and spend time talking about the animals or scenery that left an impression.

If you are with small children, older adults, or anyone with health concerns, check steps and walking distances on site and choose an order that allows you to turn back early.

Keep a Record of Your Awashima Visit

Add a Short Observation Note to Each Photo

After returning home, do more than arrange your photos. Adding one line about why something caught your attention or what connection you found between the sea and the exhibits will make the memory of your trip more concrete.

You can also record moments you did not photograph by writing about the sounds, wind, and smells.

Using the facility information to check animal and facility names lets you reflect in your own words while reducing mistaken assumptions.

Record One Improvement for Your Next Visit

Write down just one thing you would change on your next visit, such as allowing more transfer time, taking more breaks, or carrying fewer belongings.

The best way to explore will change with the season and your companions, so do not treat this plan as the single fixed answer.

Start with the day’s guidance and create an island itinerary that suits the conditions you encounter.

Awashima Guide Summary: Check the Boat and Island Conditions

Awashima is a place where you can enjoy the boat journey, observations at the aquarium and Frog House, and seaside scenery as one connected experience.

Check the return boat first and change the order of your visit as paths and weather conditions change, and you can enjoy the island without overpacking your schedule.

Prioritize the day’s information and on-site signs, remain considerate of the animals and those around you, and take one observation of your own home with you.

Frequently Asked Questions

A. Awashima Marine Park is an aquarium-style leisure facility that uses the whole of Awashima Island in Numazu, with attractions including an aquarium and the Frog House. Visitors reach the island by boat from the mainland, and the admission fee includes the round-trip fare. Unlike a land-based attraction, planning around both the outbound and return boat times helps you make the most of your limited time on the island.
A. The Frog House at Awashima Marine Park is said to have one of Japan's largest collections of frog species, with more than 50 species from Japan and around the world on display. Before trying to spot the frogs, look at the differences in their habitats, such as the water, leaves, and branches, to appreciate how their colors and postures blend into the background. Do not tap on the tanks; quietly change your viewing angle and wait.
A. The aquarium mainly features creatures that live in Suruga Bay, which stretches out directly in front of it, and on clear days the location also offers views of Mount Fuji. Rather than focusing only on names, look at body shapes, swimming styles, and where the animals hide to deepen your understanding. Spend the first minute watching without looking at a screen, then take photos to balance observation and recording.
A. From bus stop 3 at the south exit of Numazu Station, take a Tokai Bus bound for Osezaki or Nagahama; the pier is about 30 minutes away. From there, take the regular boat, which reaches Awashima in about 3 minutes each way. Because the trip involves both a bus and a boat, allow plenty of time for the connection and check the day's operating status to avoid missing either service.
A. Admission is 3,000 yen for adults aged junior high school and above, and 1,500 yen for children aged 4 through elementary school. The senior rate for visitors aged 60 and over is 2,500 yen, and proof of age is required. The fee includes the round-trip boat ride between the mainland and the island as well as admission to the shows, so there is no separate boat fare.
A. Summer hours, from March through October, are 9:30 a.m. to 5:00 p.m.; winter hours, from November through February, are 10:00 a.m. to 4:30 p.m. Ticket sales close at 3:30 p.m. in summer and 3:00 p.m. in winter, while the last boats depart at 4:50 p.m. and 4:20 p.m., respectively. The park is open year-round, but hours may change or it may close temporarily due to weather or events.
A. Awashima has slopes, wet surfaces, and steps, so choose non-slip shoes that you are used to walking in. Sea winds can blow away hats or belongings, so keeping everything in a bag that leaves both hands free will make it easier to move around. Do not judge the sunshine or temperature by the season alone; bring a jacket and drinks based on the day's forecast.
A. When you arrive on the island, first check the departure time and boarding point for the regular boat you plan to take back. Rather than waiting until after you have become absorbed in the aquarium or Frog House exhibits, share a planned departure time with your companions so you can move around calmly. Aim for the boat before the last one, not merely the final departure, to leave yourself extra time.
