Kogome no Yu湯河原温泉 こごめの湯

Kogome no Yu is the town-operated day-use onsen in Yugawara - the one locals send you to when you just want a clean soak without a ryokan commitment. It sits uphill from Yugawara Station in the onsen district, tucked against Manyo Park (Manyo Park), and has been operating for decades in the municipally-built format: a concrete-and-tatami facility, gendered bathing wings, a paid massage corner, a private-bath option, and a free rest room upstairs with a view over the onsen town.

The water is - a sodium-calcium chloride-sulfate spring, pH 8.4, source temperature in the 60-90°C range. It's the standard Yugawara-area baseline: weakly alkaline, colorless and transparent, faintly salty, with the slippery skin-feel that reviewers across fifteen-plus years consistently note. The operator's language is source-fed hot-spring water - source-fed flow-through - though at least one reviewer has reported a distinct chlorine smell, which is why we flag the water-handling question in the data notes rather than taking the marketing claim at face value.

The bath inventory: gendered indoor bath (indoor large bath) and open-air bath (outdoor bath, a roughly ten-person rock bath under a gazebo roof, sitting around 41°C), a reservable private for private use, and a bedrock bath (heated stone-slab room). No sauna, no cold bath - sauna-oriented visitors should go elsewhere. The men's and women's wings carry different names, which is typical of facilities that rotate the baths periodically; check which side is open to you the day you arrive.

The pricing is where Kogome no Yu earns its reputation as the sensible municipal option - and where the fine print matters. Daytime admission (9:00-19:00) is ¥1,100 for adults, ¥600 for elementary/junior-high students, free under school age. The evening slot (19:00-21:00) drops adult admission to ¥600 and children to ¥400 - a genuine half-price window, and the reason Kogome no Yu is a strong 'after dinner, before bed' add-on to a Yugawara day that already has a meal plan. The catch: towels are not included (¥200 hand towel, ¥550 bath towel), lockers are a non-refundable ¥100, and parking is ¥100 per 60 minutes adjacent (there's free parking 150 m uphill for planners). Budget roughly ¥1,500 for a daytime visit with rentals, or ¥900 for an evening visit if you bring your own towel.

Hours are 9:00 to 21:00 with last entry at 20:30. Closed on Mondays - bumped to Tuesday if Monday is a national holiday - plus occasional maintenance closures that aren't posted to a public schedule, so a phone confirmation (0465-63-6944) is worth it for a dated trip. Access is a ~10-minute taxi ride from Yugawara Station, or an uphill walk through the onsen district if you want the full approach. The 2F free tatami rest room, which several reviewers single out as the best feature of a visit, looks out over the town and is genuinely worth factoring in - plan the bath as a two-hour stop, not a 45-minute one.

Where Kogome no Yu sits in the Yugawara onsen mix: it is not a destination in itself. It is the dependable, low-friction, town-operated option you use when you want a real bath without booking a ryokan, when you've just come off a hike or a long lunch, or when you want to pair the soak with an 85-yen per minute massage and a view from the rest room. The water is good-but-not-rare; the facility is dated-but-characterful; the pricing is mid-tier by the hour but genuinely cheap in the evening slot. That combination is what makes it the canonical first onsen to try in town.

Colorless, transparent, slippery-silky, and warms you through - a gentle hot spring.

「塩素の匂いが凄く長湯が出来なかった事が残念です」

The chlorine smell was strong, and I couldn't soak as long as I wanted - disappointing.

These are points where the platforms and official pages we consulted gave us conflicting information.

• Water handling: The operator markets source-fed hot-spring water (source-fed flow-through) and Niftyonsen's structured profile confirms it with water added/heated/recirculated/chlorinated unpopulated. A 2010 Nifty user review, however, reports a distinct chlorine smell strong enough to shorten the soak. The most likely reality is a mixed water-handling model: source water to the main baths, with recirculation and chlorination applied to ancillary components per Japanese public-bath hygiene law. We surface both signals rather than pick a verdict.
• Hours: Tabelog's English listing shows 11:30-16:00, which is wrong. The operator's own site, the Yugawara tourism page, and Niftyonsen all confirm 9:00-21:00 with last entry at 20:30. We use 9:00-21:00. If Google shows anything different on the day you travel, trust the operator.
• Tattoo policy: No source we consulted - operator, town tourism, Nifty, or the Yugawara entry on tattoofriendlyonsen.com - names Kogome no Yu as tattoo-permitted or as explicitly prohibiting tattoos. Per our defensive default (onsen rubric §7.3) we treat this as 'unknown - call to confirm' rather than defaulting to either answer. Phone 0465-63-6944.
• Bath-name rotation: The men's and women's bathing wings carry different names. This pattern typically indicates a periodic swap where the rooms rotate between the two genders, so the specific bath you experience may depend on the day. Neither the operator nor Nifty publishes the swap schedule.
• Cleaning / days: The operator mentions 'occasional maintenance closures' but does not publish a public schedule. For a dated trip - especially one planning Kogome no Yu as the main bath of the day - call 0465-63-6944 in advance to confirm the facility is open.
• Tabelog data: Tabelog does carry a listing for this facility (3.07 / 12 reviews). The review volume is below our signal floor and the hours field is stale; we did not use Tabelog as a scoring input, only as a sanity check that was then overridden by authoritative sources.
