Yunomori Onsen & Spa is included in a current KTC wellness privilege for KTC JCB Ultimate cardmembers. The KTC wellness listing describes a free onsen entry day pass valued at THB 650 under the Yunomori x KTC JCB Ultimate campaign.
This is a narrow but useful deal: it is strongest for people who already hold the eligible card and want an onsen session rather than a full spa package.
The Offer
KTC lists the Yunomori x KTC JCB Ultimate campaign from 1 January to 31 December 2026.
The stated privilege is a free onsen entry day pass valued at THB 650.
How To Use It
Call the preferred Yunomori branch before travelling, confirm the card condition, and ask whether advance booking is needed for your visit time.
Use it as a recovery stop around Wellness, Deals and central Bangkok planning rather than treating it like an open-ended spa voucher.
