Lake Mashu (Mashuko) 
# 2   of 5 most visited sights
in Akan National Park

jump to:   access  -  ratings  -  links

Lake Mashu (, Mashūko) is a caldera lake in Akan National Park. It vies for the position of "clearest lake in the world", and is considered by many to be Japan's most beautiful lake. Lake Mashu is also one of the country's deepest lakes and although it is usually appreciated for its clear blue water, it is also famously and frequently blanketed in heavy fog.

Visitors are not allowed to go down to the lake, however there are two observation decks positioned around the rim of the caldera from where you can enjoy views. Observation Deck Number 3 lies along the western rim of the caldera and consists of two decks with unobstructed views onto the lake and Mount Mashudake. Besides free parking, there are no facilities provided.

Observation deck number 3

A five minute drive to the south lies the Observation Deck Number 1, which comes with a paid parking lot (the 410 yen fee includes parking at nearby Mount Iozan), multiple viewing decks, toilets and a large shopping area with a food stand offering various Hokkaido specialties. An observation deck number 2 used to exist between decks number 1 and 3, but has been closed to the public.

Those who wish to view Lake Mashu from even more angles will enjoy the hiking trail which leads from Observation Deck Number 1 along the rim of the caldera a third around the lake to the summit of Mount Mashudake, the prominent volcanic peak on the western side of the lake. The trail leads through forest and grassland for about seven kilometers and takes about 2.5 to 3 hours to hike one way.

How to get there
On April 1, 2014, the consumption tax increased from 5% to 8%, causing widespread changes to transportation fares. This page has not been updated yet, and some of the fees and fares in this section may not be up-to-date.

By car

Due to very poor public transportation, the recommended way to visit Lake Mashu is by rental car. The observation decks overlooking the lake can be reached in a little bit over an hour from Lake Akan or in 15 to 20 minutes from Kawayu and Lake Kussharo.

By bus

From mid July to early October, infrequent buses connect Lake Mashu's observation decks with JR Mashu Station in central Teshikaga (20 minutes) and with the western shores of Lake Kussharo (2 hours) via JR Kawayu Onsen Station (25 minutes), Mount Iozan (35 minutes) and the town of Kawayu Onsen (1 hour). A 2-day passport for the buses is available for 1800 yen.

From late April to mid July, buses run only between Mashu Station and observation deck number one (20 minutes, 540 yen one way). During the rest of the year, there is no bus service, at all.
