On the Boso Peninsula in Chiba Prefecture, about two hours from Tokyo by car, sits one of the most unusual value propositions in Japanese travel: a hilltop ocean-view resort where IT industry workers can stay for ¥6,600 per person, including a full multi-course kaiseki dinner and breakfast.
This guide covers how to use the Toslove Tateyama Luana IT-Kenpo resort, how to pair it with Kamogawa SeaWorld, and everything practical you need to plan the trip.

Kamogawa SeaWorld: How to Get the Most Out of It
The Orca Show (Orca Live)
The main draw at Kamogawa SeaWorld is the Orca Live — the orca performance. A few things to know:
- Front row seats: you will get wet. The splash zone is real. Raincoats are available for rental, but bringing your own is more reliable.
- Front row advantage: Close enough to feel the water displacement when the orca moves. The scale of the animal is only apparent from this distance.
- If you want to stay dry: Sit from row 5 onward.
- Arrive 30 minutes early to secure a good seat for the show time you want.
Admission
| Category | Price (approximate) |
|---|---|
| Adults | ¥3,500–4,000 |
| Children (middle school and under) | ¥2,000–2,500 |
| Age 3 and under | Free |
Buying tickets online in advance may be slightly cheaper.
What to See
- Orca Live — the flagship show, the reason most people come
- Walrus Show (Waldo) — surprisingly entertaining
- Dolphin Show
- Turtles area — sea turtles that make eye contact with you through the glass
- Tropical fish and coral reef exhibits
FAQ
Q: Can people who aren’t in IT-Kenpo use the resort?
A: Yes — at the non-member rate of ¥13,200/person/night including 2 meals. Availability is usually less constrained for non-members since priority goes to members first.
Q: How far is Tateyama from Kamogawa SeaWorld?
A: About 40 minutes by car. You can also travel by local bus, but a car makes the day significantly more flexible.
Q: What is October weather like in Tateyama / Kamogawa?
A: Mild and comfortable — one of the best times to visit. The coast has a sea breeze, so a light jacket is useful. After getting splashed at the orca show, bring a change of clothes.
Q: Is the resort accessible by public transportation?
A: Yes — limited express train to Tateyama Station, then the resort’s shuttle bus (reservation required). Having a car is more convenient for combining with Kamogawa SeaWorld.
Summary
If you’re enrolled in IT-Kenpo (or know someone who is), Toslove Tateyama Luana is one of the most underused employee benefits in Japanese IT. A full kaiseki dinner with fresh local seafood, an ocean-view hilltop room, communal hot spring bath — for ¥6,600 per person including meals. The equivalent experience at a comparable commercial resort would cost ¥20,000–30,000.
Combine it with Kamogawa SeaWorld on day two and you have a complete two-day itinerary that punches well above its price.
