What Is a Bus Conversion Campervan? Features, Appeal, and How to Use One in Hokkaido
A bus conversion is the largest class of campervan. Converted from a route bus or microbus, some models accommodate 10 or more passengers. Compared to cab conversions or van conversions, this is less a “house on wheels” and more a “hotel on wheels.”
This article covers the basics of bus conversions: features, advantages, disadvantages, comparison with other vehicle types, and how to use one on a Hokkaido trip.
What Is a Bus Conversion?
A bus conversion (bus conversion campervan) is a campervan created by converting the interior of a route bus, microbus, or coach into a living space. “Conversion” means the vehicle has been rebuilt to function as a home.
Based on the type of base vehicle, there are two main categories:
- Microbus-based (5–7 m): Built on Toyota Coaster, Hino Liesse, etc. Relatively compact, suited to groups of around 10.
- Full-size bus-based (8–12 m): Converted from route buses and coaches. The largest class, able to sleep 15 or more.
Basic Specifications (Microbus-Based)
| Specification | Typical Values |
|---|---|
| Length | 5.5–7.0 m (microbus-based) |
| Height | 2.7–3.2 m |
| Interior headroom | 175–200 cm |
| Passenger capacity | 6–10 |
| Sleeping capacity | 6–15 |
| License required | Medium (type 2) or larger |
| Fuel economy | 4–8 km/L |
| Rental rate guide | ¥40,000–¥80,000/day |
4 Unique Advantages of Bus Conversions
① The Largest Living Space in the Campervan Class
The defining feature of a bus conversion is its overwhelming interior space. Even a microbus-based model gives you the full interior of a 5–7 m vehicle, exceeding even cab conversions in spaciousness.
Sitting around a large dining table, having children run around inside, traveling without worrying about luggage — things impossible in a van conversion or cab conversion come naturally in a bus conversion. Groups praise the ability to spend evenings comfortably at a roadside station in Hokkaido.
② Exceptional Sleeping Capacity
Even microbus-based models sleep 6–10; full-size bus-based models can accommodate 15 or more. Being able to travel and overnight with no hotel costs for a large party is a strength only bus conversions offer.
The math can work out: “Chartering one bus conversion can be cheaper than booking 10 hotel rooms.”
③ Fully Equipped Living Facilities
Most bus conversions include:
- Full kitchen (2+ burner stove, sink, large refrigerator)
- Shower room (hot water)
- Cassette or water-flush toilet
- High-capacity house battery and solar panels
- Diesel heater (FFH) (full cabin heating) and air conditioning
- TV and Wi-Fi router
Hotel-level facilities in a vehicle you can park wherever you want — that is the core value of a bus conversion.
④ Lower Cost Per Person for Longer Trips
The daily rental fee of ¥40,000–¥80,000 sounds high, but shared among 10 people, it is ¥4,000–¥8,000 per person per day. Compare that to hotel rates of ¥8,000–¥15,000 per person per night, and a bus conversion wins significantly on longer trips.
Model calculation for 10 people, 7 nights 8 days in Hokkaido:
- Bus conversion rental: approx. ¥420,000 (¥60,000/day × 7 days)
- Per person: ¥42,000 (equivalent to 7 nights of accommodation)
- Hotel comparison: 10 people × 7 nights × ¥10,000 = ¥700,000
- Difference: ▲¥258,000 (bus conversion is cheaper)
Disadvantages and Cautions
① Medium or Larger License Required
Most bus conversions have a gross vehicle weight of 5 tonnes or more, requiring a medium license (for those who obtained their standard license after 2007) or the old-style standard license (pre-2007, covering up to 8 tonnes GVW). Full-size bus models require a large vehicle license.
Those who obtained a standard license after 2007 generally cannot drive a bus conversion — always verify license requirements before booking. Having someone in your group with a medium or large license is a prerequisite.
② Limited Parking Options
At 5–7 m+ in length and 2.7 m+ in height, parking options are severely limited. Small tourist car parks and narrow roads are often inaccessible. Plan ahead and use spacious parking lots, roadside stations (michi-no-eki), and RV parks.
Hokkaido has many large flat car parks that are bus conversion-friendly, but some areas — such as the central tourist district of Hakodate — require extra care.
If you are starting your trip from Hakodate or the southern Hokkaido area, check the Hakodate campervan rental comparison as well.
③ Poor Fuel Economy, High Fuel Costs
Fuel economy is 4–8 km/L. Driving 200 km/day in Hokkaido costs approximately ¥5,000–¥8,500 in diesel (¥170/L). For a 7-day trip, fuel alone can total ¥35,000–¥60,000 — factor this into your group cost calculation.
④ Driving Requires Practice
A nearly 7 m-long vehicle handles very differently from a standard car at corners and when parking. Backup cameras and careful mirror checks are essential — receive a thorough briefing from the rental company before departure.

FAQ
Q. Can I drive a bus conversion with a standard license?
Most models require a medium license or larger. Those who obtained their standard license before 2007 may be covered under the old-style standard license (up to 8 tonnes GVW) in some cases — always confirm with the rental company.
Q. How much is the per-person rental cost for a bus conversion?
For 10 people, roughly ¥4,000–¥8,000 per person per day. Over 7 nights and 8 days, that is ¥28,000–¥56,000 per person. Compared to the same number of hotel nights, a bus conversion is usually cheaper for groups of 6 or more.
Q. Where can a bus conversion be parked?
The vehicle’s length and height rule out multi-story car parks and height-restricted areas. Plan your route around roadside stations, RV parks, and large flat commercial parking lots. Hokkaido has many such options, making it well suited for bus conversion travel.
Q. Which is better for Hokkaido travel — a bus conversion or a cab conversion?
Think by group size: 4–6 people → cab conversion; 6+ people → bus conversion. If everyone in your group has only a standard license, a cab conversion is the only option.
Q. Can I rent a bus conversion in Hokkaido?
Bus conversion rental companies are rare nationwide, and Hokkaido locations are limited. Availability during peak season (July–August) fills up months in advance — check and reserve early.
