Himeji Castle and Arima Onsen: World Heritage Castle and Japan Oldest Hot Spring

A pure-white keep set against the blue sky, and a hot spring town wreathed in steam among the mountains. Hyogo Prefecture holds two great attractions: Himeji Castle, the national treasure and World Heritage Site, and Arima Onsen, said to be Japan oldest hot spring resort. The elegant castle nicknamed White Heron Castle and the famous spring with over a thousand years of history let you savor both historical romance and relaxation, together with the exotic streets of Kobe.

Highlights

White Heron Castle, the National Treasure Himeji Castle Himeji Castle rises over the city of Himeji as one of Japan foremost castles. Its graceful form, finished in white plaster, earns it the name Shirasagi-jo, or White Heron Castle. With its keep built in the early Edo period and many surviving structures, it is regarded as the finest masterpiece of Japanese castle architecture. A national treasure, it was among the first sites registered as a World Cultural Heritage in Japan in 1993. Its cunning layout designed to confuse attackers is a highlight, and the adjacent Japanese garden Kokoen can be enjoyed alongside it.

Arima Onsen, Japan Oldest Hot Spring Arima Onsen, on the north side of Mount Rokko in Kita Ward of Kobe, is a historic hot spring counted among Japan three oldest springs. It appears in ancient records and is known as a favorite of the warlord Toyotomi Hideyoshi. Its great feature is two contrasting waters: the reddish-brown, iron-rich kin-no-yu (gold spring) and the colorless gin-no-yu (silver spring). Public baths such as Kin-no-yu and Gin-no-yu let visitors soak, and the atmospheric slopes and lanes of the town are a pleasure to stroll.

The Exotic Atmosphere of Kobe Hyogo charm goes beyond Himeji Castle and Arima Onsen. The port town of Kobe brims with the exotic air of its history since the port opened. In the Kitano district, Meiji-era Western residences line the streets in an exotic mood. Kobe also offers the Nankinmachi Chinatown, the harbor scenery of Meriken Park, and beautiful night views from the hillsides, along with fine cuisine including Kobe beef and stylish town walks.

Seasonal Enjoyment

Himeji Castle can be enjoyed year-round, but it is especially beautiful in cherry blossom season (late March to early April) and autumn foliage (November), when the white castle contrasts exquisitely with blossoms or red leaves. Arima Onsen is comfortable throughout the year, and the mountain town is atmospheric in fresh greenery and autumn color alike. Winter snow lends the steam and snowscape a magical air. Kobe night views shine most beautifully in the clear air of autumn and winter.

Practical Travel Notes

Himeji Castle takes about 1.5 to 2 hours to tour up to the keep, and about half a day including Kokoen. Weekends during cherry blossom or autumn season and long holidays are crowded, so early-morning entry is recommended. Arima Onsen is ideally enjoyed with an overnight stay for leisurely bathing, though Kin-no-yu and Gin-no-yu allow day-trip bathing too. A common two-day plan is Himeji on day one and Arima and Kobe on day two. Budget-wise, Himeji Castle admission is 1,050 yen, Arima public baths a few hundred yen, and a Kobe beef lunch from around a thousand yen, so the trip can be tailored widely. Popular Arima inns are best booked early.

A Word of Advice

Himeji Castle grounds are extensive and the keep involves many stairs, so wear comfortable shoes. During busy periods entry to the keep may be restricted, so allow plenty of time. At Arima, soak in the famous kin-no-yu waters while enjoying the sloping town and the local tansan senbei carbonated crackers. A trip linking Himeji, Arima, and Kobe is a luxurious itinerary taking in the varied charms of Hyogo all at once: a World Heritage castle, Japan oldest spring, and a port town exotic air.
