Ryokan FAQs

Do all rooms at every ryokan on Private Japan have a private onsen?

Yes. Unlike general booking platforms that mix standard rooms with suites, Private Japan only lists ryokan where 100% of guest rooms or villas have their own attached private onsen.

What is the difference between Traditional and Modern ryokan styles?

Traditional ryokan feature tatami-matted floors, shoji (sliding paper screens), and classic Japanese timber architecture, while Modern ryokan combine private hot-spring bathing and kaiseki (multi-course seasonal dining) with proper Western beds and contemporary suite or villa design.

Which region should I choose for my first ryokan stay?

Hakone and Kawaguchiko are convenient from Tokyo, while Kyushu offers deeper mountain onsen culture and Hokkaido is ideal for nature-led escapes with cooler climates.

How long should I stay at a ryokan?

Two nights is often ideal: one to settle into the rhythm of private onsen bathing and multi-course dining, and another to fully experience the setting and nearby cultural landscapes.
