Lake Kasumigaura | A Vast Sky and Horizon at Japan's Second Largest Lake

Lake Kasumigaura spans approximately 220 square kilometers, making it Japan's second largest lake after Lake Biwa in Shiga Prefecture. Spreading gracefully across the flat Kanto Plain, the lake resembles an inland sea. The magnificent view where sky and water become one sets the spirit free. This iconic natural landmark of Ibaraki is full of unique pleasures, from the traditional fishing method of hobiki-bune (sail boats) that hoist sails to catch fish, to cycling along the lakeshore.

Japan's Second Largest Lake

Lake Kasumigaura spreads across the southeastern part of Ibaraki Prefecture. The lake is so vast that the opposite shore is lost in haze, and this very characteristic is said to be the origin of its name. It was once an inlet connected to the sea, but over long ages it became the enclosed lake it is today. Rich in aquatic resources, the lake has long supported active fishing, with smelt, ice fish (shirauo), carp, and eel among the catches. The expansive water surface and the peaceful rural scenery surrounding it form an open landscape characteristic of the Kanto Plain. The grand view woven by water and sky welcomes those who visit.

The Traditional Hobiki-bune

The most iconic sight of Lake Kasumigaura is the hobiki-bune, boats that spread large white sails. Devised in the Meiji era, this fishing method drifts the boat sideways with the power of the wind while drawing in the nets to catch fish. The sight of large white sails floating on the lake is graceful and conveys the fishing scenery of old Kasumigaura to the present. Today the operation is recreated seasonally for tourism, and you can view the beautiful boats from a sightseeing vessel. The scene of white sails against the blue water is popular with photographers. Since operating days are limited, it is safest to check the schedule in advance with the local tourism association.

Lakeshore Cycling and Sightseeing

Lake Kasumigaura is also known as a cycling destination around its shore. The "Tsukuba Kasumigaura Rinrin Road," linking Mount Tsukuba and Lake Kasumigaura, is a National Cycle Route of about 180 kilometers, and the course circling Kasumigaura is about 125 kilometers. With much of the route flat, it can be enjoyed by everyone from beginners to serious riders. Rental bicycles are available, and pedaling while taking in the grand lake scenery is exceptionally refreshing. Parks and facilities where you can learn about the lake's nature dot the shore, and families can enjoy it too. There are also eateries serving fresh lake produce, letting you savor the bounty of Kasumigaura.

The Tsuchiura Fireworks

In Tsuchiura City, close to Lake Kasumigaura, the "Tsuchiura All Japan Fireworks Competition" is held in autumn. Counted among Japan's three great fireworks events, this traditional competition, held along the banks of the Sakura River, gathers pyrotechnicians from across the country to compete in skill. It is a major Ibaraki event that draws many spectators each year. Since dates and seating information vary by year, check the latest details on the competition's official website.

Access and Basic Information

From Tokyo: About one hour by JR Joban Line limited express from Ueno Station to Tsuchiura Station. Tsuchiura Station is close to the shore of Lake Kasumigaura and is convenient as a cycling base. By car: The lakeshore can be reached from the Tsuchiura-Kita IC and other exits on the Joban Expressway.

Practical Travel Notes

• Recommended season: The lake can be enjoyed year-round, but cycling is most comfortable in the mild seasons of spring (April to May) and autumn (October to November). The tourism operation of the hobiki-bune is often carried out from summer into autumn.
• Time needed: Allow a half day for a lakeshore stroll or short ride, and a full day or more if you attempt the long ride around the entire lake.
• Avoiding crowds: On the day of the Tsuchiura All Japan Fireworks Competition, the city of Tsuchiura becomes extremely crowded. If your aim is the fireworks, arranging transport and lodging early is essential.
• Nearby spots: Combining a walk through Tsuchiura, lakeside parks, and rest spots along the Rinrin Road makes for a full outing.
• Budget sense: Strolling the lakeshore and using the cycling road are basically free. Rental bicycles, sightseeing boats, and hobiki-bune viewing carry separate fees.

A Word of Advice

Lake Kasumigaura is a vast lake with two draws, lakeshore cycling and the hobiki-bune. The Rinrin Road is flat and easy to ride, recommended even for beginners. Because the hobiki-bune operates only on limited days, those wanting to see it should check the schedule in advance. If you time your visit for the autumn Tsuchiura fireworks competition, booking transport and lodging early is the key to enjoying it comfortably.
