Hokkaido’s Largest Lake Saroma-ko

Limitless and spread out, Saroma-ko (サロマ湖) is Hokkaido’s largest lake (152-sq-km) as well as Japan’s largest lagoon connected with the Sea of Okhotsk. Sunsets over the lake are particularly spectacular.

If you have time to visit Abashiri or Kitami, we highly recommend spend the night at the gentle lakeside. There are virtually no daily bus service on the southern shore, so your own wheels will allow you to fully get around the lake.


Wakka Genseikaen

(ワッカ原生花園) Japan’s largest coastal wildflower garden on a 20km-long sandbank sandwiched between the Sea of Okohotsk and Saroma-ko, with over 300 species of colorful flowers bloom from May to October.

The Wakka Nature Center (ワッカネイチャーセンター) has information, maps and rental bikes (¥600). From here, the Ryugu Kaido trail (竜宮街道: 10km return) leads to the spring water of Wakka-no-Mizu (ワッカの水) in the westward. Other trails lead to the eastward along the sandy coast.

Wakka Genseikaen is about 1km west of the Gyokyo Shisho-iriguchi (漁協支所入口) stop on Kitami municipal bus route from Tokoro bus terminal.
