Kagamiyama Onsen Chaya Bijin-no-Yu, Karatsu
A day spa on Route 202 in Karatsu, right beside Niji-no-Matsubara, one of Japan's three great pine groves, and an easy 10-minute walk from JR Niji-no-Matsubara Station. The mildly alkaline simple spring is used free-flowing and lives up to its 'beauty bath' name with a silky feel. There are tepid and hot tubs, an open-air bath, sauna and cold plunge, plus three private family baths (rock, barrel and so on; extra charge, booking until 20:00). Adults ¥800, children ¥450; open 10:00–22:00 (last entry 21:30), closed the third Thursday (open daily in January, February and August; special closure on December 31). The restaurant serves set meals with Karatsu fish, and as a pilgrimage spot for the anime 'Yuri!!! on Ice' the building has a fan display corner. Fits between Karatsu Castle, the Yobuko morning market and a drive along the pines, or as the finish to a day trip from Fukuoka — about an hour by car from the city. 50 parking spaces.
