Japanese Speedboat Racing Experience

Dynamite Boat Race is the most popular high-octane on-water motorsport in Japan.

BOATRACE athletes compete in lightweight, wooden boats that are hand cut, carefully crafted, and assembled in Japan each year. Only 1,600 boats are made per year, and each one features a stock outboard motor and is retired after only one season

Introduced in Japan in 1952, competitive speedboat racing (kyōtei) is one of Japan’s four sports (kōei kyōgi) that permit members of the public to legally place bets.

In this speedboat racing experience, you’ll receive an introduction to the Boat Race Hamanako facilities and instruction on how to watch boat racing and use Betting Cards.

The experience includes two cards: an Optical Mark Recognition (OMR) Betting Card and one prepaid e-money card charged with 1800 JPY. Use the OMR card to select winning boats, then hold the prepaid e-money card over the reader to place a bet.

Japan Boat Race Basics

In Japanese powerboat racing, all of the boats in each race are basically the same, making this a competition based on the physical and mental skills of the racers.

On any given race day, there will be a total of 12 races in one day. Six boats will compete in each race. In each race, the boats and racers use the same numbers and colors according to their initial lane position:
Boat 1: White
Boat 2: Black
Boat 3: Red
Boat 4: Blue
Boat 5: Yellow
Boat 6: Green

Unlike most racing events, a boat race in Japan does not begin with a typical standing start. Instead, the racers are turned loose about 100 seconds before the race starts to jockey for position and, hopefully, achieve the best flying start within the designated time.
As a giant clock counts down to the start of the race, the drivers will all navigate their boats around the first buoy, head towards the back straight and around the second buoy.
Here, each driver will steer their boat back towards the starting line again to achieve the desired starting place. None of this activity is part of the actual race. Rather this part of the event is all about each racer trying to create even the smallest advantage in position over his opponents.

The drivers all jockey for the best position at low speeds until about 30 seconds before the clock reaches zero. The goal for each driver is to get his boat over the starting line at full speed as soon as the clock hits zero.
Most importantly, if any boat crosses the starting line either before the clock hits zero, or too long after the clock hits zero, that driver is automatically disqualified from the race and scratched from the card.
After each nerve-racking start, the ensuing race consists of three laps around the course, which takes these speedy crafts only about a minute to complete.
When the boats are ready, the drivers take to the waters for a practice race, followed by timed 150-meter runs. This is partly to test the boats, but mainly to give you another chance to assess the field.
After the warm up, everyone is ready for an actual race to begin. The boats will start off together from the dock. When the signal is given, each driver points his boat towards the starting line.
