What the official information does—and does not—say
Hagi Komachi’s spa page explains its open-air baths, large rock baths and private bath, but does not publish a general day-use ticket, admission hours or an outside-visitor policy. Hagi’s tourism association does not include it in its day-use onsen listing either. That is not the same as a confirmed ban; it means you should not arrive expecting the public day-bath arrangement offered by nearby hotels.
The private bath is listed at ¥3,300 for 45 minutes, by reservation, between 15:00 and 23:00. The page does not say whether a non-overnight guest can reserve it on its own. Confirm eligibility, date availability and payment directly with the hotel before relying on it.
The hotel does publish an overnight guest shuttle that can be reserved from Higashi-Hagi Station, Hagi Bus Center and Meirin Gakusha, with pickup times between 15:00 and 19:00. That is lodging transport, not evidence that a day visitor can use the baths or book a transfer. If you are asking about a special meal-and-bath plan or outside use of the private bath, confirm both admission and transport with the hotel first.
One important detail about the rock baths
The baths named Uminari-no-Yu and Araiso-no-Yu use large natural rocks from the Sea of Japan, but the hotel explicitly says these rock baths are not hot springs. The two open-air baths are a separate feature and face the sea. The private bath is described as using Hagi Onsen.
The hotel’s “six bath-hopping experiences” refers to bathing areas and experiences, not six separate springs. The two sea-facing outdoor baths are Yūhi-no-Yu and Yūnami-no-Yu; Uminari-no-Yu and Araiso-no-Yu are the large-rock baths. The reserved private bath is a half-outdoor Hagi Onsen bath.
The page lists two cold-mineral spring categories: a weakly radioactive calcium-sodium chloride spring and a calcium-sodium chloride spring. It does not publish a separate source temperature, pH or flow rate for either, or map each public pool to a specific spring.
The private bath is half-open-air and faces the sea; the room also lists a toilet, television, drinking water and children’s amenities. Those features do not clarify whether non-guests can reserve it or whether the fee includes general admission, so confirm both points with the hotel.
That distinction matters if the reason for visiting is a natural hot spring rather than a seaside bathing setting. A stay gives you the clearest route to using the hotel facilities; if you want a confirmed public day bath, check the Hagi Kanko Hotel guide or Resort Hotel Mihagi guide instead.
If you are considering an overnight stay
Hagi Komachi is in the Koshigahama area on the Sea of Japan coast, away from the castle-town center. Its open-air baths face the sea, and the private bath adds a reserved option for a group that wants a more private session. Check your room and meal plan, plus the route to the hotel, before choosing it as a base for central Hagi sightseeing.
Its coastal setting is different from the other sea-view options around Hagi. Hagi Kanko Hotel is higher on Mount Kasayama, with a day-use bath looking across Hagi Bay; Mihagi is beside Kikugahama and the castle-town walking route. Komachi is farther out toward Koshigahama and is best treated as a stay in its own right, rather than a confirmed day-bath stop. Do not transfer spring figures from either nearby hotel to Komachi: its published page gives spring categories but not the individual analysis values.
Confirm day-use eligibility and private-bath reservations before setting out.
