Lake Toya to Sapporo

Should I take the inland or coastal train route from Lake Toya to Sapporo, travelling February. Which is more scenic / interesting in winter?

From Toya eki mae, you need 2880 yen,197 min to sapporo by toyoura highway express bus beside train journey

Thank youc.so is the inland route by bus only? And the coastal route by train?

From JR Toya to JR sapporo,you need 3630 yen,in this travel you will see

is the inland route by bus only? And the coastal route by train?

You can check by yourself by googling gFrom toyako onsen to sapporoh. Basically there seems to be two routes: Direct bus (inland) and combination of bus to JR Toya station and limited express train (coastal) to Sapporo.

Direct bus: less frequent, takes more time, uncomfortable (you canft leave your seats for about 3 hours) but inexpensive.

Bus/train: frequent, fast, comfortable but expensive.

As for scenery, the weather will be snowy, so there will not be much difference.
