10 Things to Know Before Taking the Osaka to Beppu Ferry with Kids

Bychime

Traveling across Japan with kids doesn’t always mean rushing through train stations or juggling luggage on crowded platforms. When we planned our family trip from Osaka to Beppu, we chose the overnight ferry—and it turned out to be one of the most memorable parts of our journey.

The Sunflower Ferry isn’t just a way to travel between Osaka and Beppu — it offers hotel-like facilities onboard, including spacious cabins, a restaurant buffet, and large communal baths where passengers can relax while gazing at the ocean. The public bathing areas — akin to a traditional Japanese sento — are one of the ferry’s most-loved features and a highlight of the overnight journey.

If you’re considering the Osaka–Beppu ferry with children, here are 10 important things to know before you book.

1. It’s an Overnight Ferry (and That’s a Good Thing)

The ferry usually departs in the evening and arrives in Beppu early the next morning. For families, this means:

  • No lost sightseeing day
  • Kids sleep while you travel
  • You wake up in a new city

It feels more like staying in a floating hotel than transportation. This ferry is widely used by locals too for transportation. Don’t be surprised if big trucks and cars board the ferry along with your family.

2. Tickets can sell out fast

  • It is advisable to get your tickets in advance to avoid any changes and unwanted delays in your trip plan. We bought ours two months in advance.
  • Ferry fares vary depending days of the week and the season.
  • Kids have discounted fares.
  • It’s cheaper when you buy a round ticket.
  • You need to get a physical ticket at the counter when you check in.
  • Tickets with barcodes are also your key to your cabins. Keep them safe.
  • Boarding is smooth.
  • Staff are helpful.

Arrive early, let kids watch the ship prepare, and boarding becomes part of the experience.

3. Luggage Is Much Easier Than Trains

One of the biggest family travel wins:

  • No lifting bags onto overhead racks
  • No rushing to catch trains
  • Plenty of space for suitcases
  • Luggage storage outside cabins

You can roll your luggage onboard and relax.

4. Family Cabins Are Worth It

You’ll typically find:

  • Private family cabins
  • Japanese-style tatami rooms
  • Shared sleeping areas, dorm style with privacy curtains

With children, a private or family cabin is 100% worth the upgrade—especially for bedtime routines and early wake-ups.

If cabins are sold out, shared rooms are still doable—but private space makes a huge difference for bedtime routines. The private beds come in a dorm-style with four beds in a corner with privacy curtains. So if you have a big group, four of those beds could be all your group and have a nice private space.

5. There’s an Onsen Onboard (Yes, Really)

One of the biggest surprises for us was the onboard public bath (onsen).

Things to know:

  • Separate baths for men and women
  • Kids are allowed (check age guidelines)
  • It’s a very Japanese experience
  • The onsens have a schedule, and mornings are quite busy as people try to get ready before disembarking the ferry.
  • Cameras are not allowed in the onsen and bathroom areas.
  • The onsen overlooking the ocean from the ferry window is something you don’t want to miss.

6. Kids Love Exploring the Ship

The ferry isn’t boring at all:

  • Wide hallways
  • Deck views of the ocean
  • Vending machines everywhere
  • Lounge and seating areas
  • Projection mapping shows on board
  • live music
  • play area
  • gift shop; don’t forget to get your ferry stamp if you are collecting them during your Japan visit.

For kids, it feels like an adventure, not just a means of transportation.

7. Food Is Easy (Even for Picky Eaters)

Most Osaka–Beppu ferries offer:

  • Cafeteria-style meals
  • Simple Japanese dishes
  • Snacks and drinks from vending machines
  • Cup o noodles from vending machines

Tip: Bring a few familiar snacks just in case—especially for younger kids.

8. Seasickness Is Rare (But Plan Just in Case)

The ferry is large and stable, and most people feel fine. Still:

  • Choose a lower-deck cabin if possible
  • Bring motion sickness bands or medicine
  • Fresh air on deck helps
  • There are seasickness sinks in the bathroom

9. Mornings Are Magical

Waking up as the ferry arrives in Beppu is special:

  • Soft morning light
  • Ocean views
  • Kids are excited to spot land

It’s a calm, memorable way to arrive—much nicer than stepping off a train exhausted.

10. It Becomes a Highlight, Not Just Transport

Instead of being “the way to get there,” the ferry became:

  • A fun sleepover
  • A cultural experience
  • A break from fast-paced travel

For families, that slower pace can be exactly what you need.

We traveled from Osaka to Beppu round-trip on an overnight ferry with our kids—and it was one of the most relaxing parts of our Japan trip.

Booking the Osaka to Beppu Ferry (Family Tips)

We booked our ferry tickets 2 months in advance to secure private bedrooms, which I highly recommend if you’re traveling with kids. There are more private and luxurious room options, depending on your budget. We are budget travellers.

Why book early?

  • Family cabins sell out fast
  • Ferry prices vary from day to day, and booking early helps to lock in those cheaper days.
  • Better cabin location choices
  • Peace of mind before travel day
  • If you are on a tight schedule during your trip, you may want to allocate all the days for specific hotels, trains, and ferries.
