This steaming, hissing mountain (512m), a couple of kilometres south of Kawayu Onsen, comes complete with sunshine-yellow sulphur and onsen-steamed eggs. Chances are you'll hear the sellers calling Tamago! Tamago! Tamago! (Eggs!) even before you reach the car park.
About 4km northwest of JR Furano station and overlooking the valley, it's almost obligatory to visit this winery, check out the wine-making process and indulge in a complimentary tipple.
Mention you've been to Hakodate and every Japanese person you know will ask if you took in the night view from atop Hakodate-yama – it's that famous! Take the ropeway (gondola) to the top for amazing views over the city. Take tram 2 or 5 to the J?jigai stop, and walk uphill to the ropeway station. Alternatively, a summit-bound bus (¥360, 30 minutes) leaves directly from JR Hakodate Station, and stops at several viewing places as it winds to the top. You can also drive up or take the hiking track (from May to late October).
