Fireflies dancing in the twilight of the rural mountains, enjoying the atmosphere of a rain-soaked castle town. 15% OFF campaign for adults' summer vacation.
In June and July, before the full-fledged summer arrives, this period has traditionally been regarded as the season when the beauty of 'silence' is at its peak, as people appreciate the coolness by the water and the fresh greenery.
The luxury of travel lies in being freed from the crowds and having the space to fully enjoy the local atmosphere.
That’s why, rather than waiting for the height of summer, why not embark on an early summer trip to quickly obtain the heart-soothing "coolness"?
This time, at Sasayama Castle Town Hotel Nipponia, we have prepared valuable coupons available for use during this period as part of our 'Adult Summer Vacation Campaign'.
❚ Recommendation for Early Summer
In early summer, Tanba Sasayama offers a landscape unique to satoyama blessed with clear waters. In June, natural fireflies begin to emit a soft light in the tributaries of the Sasayama River and the waterways of the satoyama.
The sound of frogs overlaps with the sound of the babbling stream, leaving trails of light dancing in the air. Enjoy the original scenery of Japan that can only be encountered in a place protected by rich soil and clear water.
＜Firefly Viewing in Tanba Sasayama＞
Best time: Early June to late June
Main spots: Around Fujioka River, Miyadame River, tributaries of Sasayama River (5 minutes on foot from the hotel)
In June, the mountains of Tanba-Sasayama are enveloped in a unique landscape as the "chestnut flowers" bloom, creating a white, smoky appearance. Particularly, the area around "Oujiyama Park" within walking distance from the hotel is a highlight.
The streets of Kawaramachi, which retain traces of the Edo period, gain even more charm when wet from the rain. Enjoy a cup of coffee or tea in a calm café. Spend your time with the gentle sound of rain.
In late July, ahead of the "Dekansho Festival" in August, the sounds of the Dekansho folk song begin to be heard all over Tanba Sasayama.
Every year, practice sessions and pre-events are held in the lead-up to the main festival, and the entire castle town quietly comes alive as summer approaches. Why not get a head start and experience the feeling of old-fashioned Japanese summer beginning in the townscape that has been designated a Japan Heritage site?
<Dekansho Festival>
Period: August 15th and 16th every year (scheduled for Saturday and Sunday in 2026)
Location: San-no-maru Plaza, ruins of Sasayama Castle (about an 8-minute walk from the hotel)
Official website: https://dekansho.jp/
Please enjoy French cuisine made with plenty of Tajima beef, which is a pride of Tamba-Sasayama, and seasonal summer vegetables. After your meal, change into a yukata* and take a stroll through the quiet castle town, feeling the sound of wooden sandals and the pleasant night breeze. In your room, relax and immerse yourself in the charm of historical architecture.
*This is a simple yukata provided as nightwear.
