From Mashu Station in Teshikaga, Lake Mashu is a 15- to 20-minute drive away; buses run between the station and the lake year-round, but irregularly. This connection provides a concrete starting point for planning your trip. At 900 Grassland, you can add Park Golf and scenic views, while the highly acidic Kawayu Onsen spring offers a different focus.

Getting to Lake Mashu: Plan for a Car or Bus

The 15- to 20-minute journey time applies to the drive from Mashu Station to the lake. If traveling by bus, check the seasonal details of public transport in advance. Although the connection operates year-round, buses run irregularly. This gives you two distinct factors to consider when planning: a stated driving time and a public transport connection without a regular timetable. You can gauge the drive by its travel time; checking seasonal details is a separate planning step for the bus.

900 Grassland: Park Golf and Scenic Views

900 Grassland lies just south of the town of Teshikaga. Its Park Golf course has four courses with a total of 36 holes and is recognized by the International Park Golf Association. The same grassland is home to an observation building with 360-degree views of Mount Mashu, Mount Iō, and Mount Mokoto. This brings two distinct highlights together in one place: Park Golf and views of three mountains. The four courses and 36 holes describe the scale of the course; the 360-degree view refers to the panoramic outlook from the observation building. If you want to include both sports and scenery, you can plan for both here without treating them as the same thing. Depending on your interests, you can consider 900 Grassland as a Park Golf destination, a scenic viewpoint, or both.

Kawayu Onsen: A Highly Acidic Spring

The Kawayu Onsen spring in Teshikaga is highly acidic, with a pH of 1.7 to 1.9. This gives the spring a geological dimension alongside questions of transport and scenery. The description “highly acidic” and the numerical range complement each other: the first names the property, while the pH range specifies it. This feature distinguishes Kawayu Onsen from the sporting and scenic highlights of 900 Grassland. For travelers interested in geological features when choosing a destination, the spring is a point of interest in its own right. On the pH scale, seven is neutral; values below it are acidic, while values above it are alkaline. The range of 1.7 to 1.9 is therefore well within the acidic range. Because the scale is logarithmic, equal numerical differences do not correspond to equal linear changes in acidity. This explains how pH values help classify the acidity of the spring more precisely.
