Supporting the Safe Operation of the New Vessel Royal II


Every year 19,000,000 tourists visit Lake Ashi in Hakone, Kanagawa Prefecture. At Lake Ashi, with its beautiful scenery of blue water, green mountains, and the magnificent Mt. Fuji, the Hakone Sightseeing Cruise is extremely popular.
Three cruise ships built to resemble the pirate sailing ships of old delight large numbers of tourists.

In March, 2013, the cruise ship Royal was retired, and the new Royal II began operation. The new ship is equipped with the latest cruising equipment and fitted out with barrier free facilities. Here we introduce the “navigational support device” and “passenger cabin information monitor” systems on the Royal II, which were supplied by Akasakatec.

Docking Support System

Docking Support System for Passenger Ships and Sightseeing Boats
Supporting the Safe Operation of Passenger Ships and Sightseeing Boats.


A support device with on-screen displays of lake shore, piers, and the ship’s position, supporting safer operation and docking.

When a vessel is underway, its operator constantly checks buoys and the lake shore as position guides, checking the ship’s position while referring to displays on the instrument panel such as radar, adjusting the ship’s speed and angle to determine its course.

Even at times of poor visibility such as fog, the device allows the ship’s current position to be checked on screen, so the distance from buoys and the lake shore can be visually confirmed. In normal conditions the operation support device can be used with almost no operator supervision, and the on-screen diagram is displayed at an appropriate scale in accordance with the ship’s current position.

Cabin Information Monitor

Information Display Device for Passenger Ships and Sightseeing Boats
Visually Displays Estimated Arrival Times and Tourist Information

The cabin information monitors are particularly helpful for elderly passengers or the hard of hearing, and provide information such as estimated arrival time, current position etc.

When schedule changes due to fog occur, up-to-date information is provided to passengers by map display as well as voice.
The system contributes to passenger safety by including information and instructions on emergency escape routes and life-saving equipment.


In recent years, many foreign tourists, such as those from Asia, visit the area, and so announcements are made in several languages (Japanese, English, Chinese, Korean)
There are many well-known tourist spots around Lake Ashi, such as Hakone Jinja, Hakone Sekisho and Fukara Suimon, so there is also a function that provides tourist information to regular passengers with photographs and videos.

In the Cabins

Onboard monitors display up-to-date information about the ship in real time.


Monitors are all managed from a touch panel computer. The touch panel’s easy operation means that it can be used without interfering with the safe operation of the ship by the crew members. It can wall-mounted to save space.
