Of all the major cities in Japan, Osaka offers the most convenient access to the country’s two primary ninja heritage sites. Iga is approximately 90 minutes away; Koka is 60–70 minutes. This guide covers the routes, transit costs, and what you will find at each destination.
Why Osaka is the ideal base for ninja travel
The historical shinobi heartlands of Iga (伊賀, Mie Prefecture) and Koka (甲賀, Shiga Prefecture) both sit within easy day-trip range of Osaka. The two provinces face each other across the Suzuka mountain range — the same geographic barrier that historically defined the boundary between their respective ninja traditions — and Osaka sits at the southern end of that corridor.
From Osaka, both sites can be visited on separate days without rushing. Visiting both in a single trip is straightforward, and the transit time in each case leaves a full afternoon at the destination. Visitors based in Kyoto have similarly convenient access; the routes overlap substantially.
Day trip to Iga (Mie Prefecture)
Iga is the most historically documented ninja region in Japan and home to the Iga-ryu Ninja Museum — the most serious historical shinobi site in the country. The museum holds genuine period artifacts, a reconstructed shinobi residence with functional concealment mechanisms, and exhibits grounded in primary sources including the Bansenshūkai (1676).
Route from Osaka
The standard route uses the Kintetsu Osaka Line from Osaka Uehommachi or Tsuruhashi station.
- Osaka Uehommachi → Yamato-Yagi: Kintetsu Osaka Line limited express, approx. 35–40 min
- Yamato-Yagi → Iga-Kanbe: Kintetsu Osaka Line local, approx. 40 min
- Iga-Kanbe → Ueno-shi: Iga Railway, approx. 25 min
- Total one-way: approx. 90 min (approx. ¥1,500–¥2,000 as of June 2026; fares vary by train type and booking method)
A limited express supplement applies on the Kintetsu section. The Iga Railway portion is a small local line — IC cards are not accepted; purchase a ticket at the machine at Iga-Kanbe station.
From Ueno-shi station, the museum and Iga Ueno Castle are a 15-minute walk through Ueno Park.
At the site
- Hours (weekdays): 10:00–16:00 (last entry 15:30)
- Hours (weekends & public holidays): 10:00–16:30 (last entry 16:00)
- Admission: ¥1,000 adult; combination tickets with Iga Ueno Castle available
- Recommended time: 2–3 hours for museum and castle combined
Departing Osaka around 8:30–9:00 gives a comfortable arrival by 10:30 and leaves the full afternoon at the site before a relaxed return journey.

Day trip to Koka (Shiga Prefecture)
Koka is the other half of Japan’s twin shinobi tradition. The Bansenshūkai — the most comprehensive surviving ninjutsu manual — draws explicitly on both Iga and Koka as its source traditions, making Koka of equal historical significance even though it receives fewer visitors.
The Koka Ninja Village (甲賀の里 忍術村) offers a more hands-on experience than the Iga museum, with practical demonstrations of techniques and equipment including kusarigama, climbing tools, and shinobi devices. The site is set in woodland, which reflects the forested mountain terrain in which the Koka tradition actually developed.
Route from Osaka
- Osaka → Kusatsu: JR Biwako Line (via Kyoto), approx. 50–60 min (approx. ¥1,000–¥1,200 as of June 2026; fares vary by train type and booking method)
- Kusatsu → Koka Ninja Village: Local bus or taxi, approx. 30–40 min. Bus schedules are infrequent — check timetables in advance. Taxi is the most reliable option (approx. ¥3,000–¥4,000 one-way as of June 2026)
- Total one-way: approx. 60–70 min by train + local transit (approx. ¥4,000–¥5,500 as of June 2026; subject to variation by season and booking method)
Koka is the shorter journey from Osaka of the two destinations, making it practical even for a half-day visit.
At the site
- Hours: 10:00–17:00 (last entry 16:00)
- Closed: Mondays (check the official schedule for seasonal closures)
- Admission: ¥2,000 adult (includes trick house and Ninjutsu Museum)
- Recommended time: 2–3 hours

Visiting both Iga and Koka from Osaka
With Osaka as a base, visiting both sites on consecutive days is straightforward and unhurried. A suggested two-day structure:
Day 1 — Iga
- Depart Osaka Uehommachi around 8:30–9:00
- Arrive Ueno-shi approx. 10:00–10:30
- Iga-ryu Ninja Museum (2 hours) + Iga Ueno Castle (1 hour)
- Explore the old castle town; dinner in Iga or return to Osaka by early evening
Day 2 — Koka
- Depart Osaka around 9:00
- Arrive Kusatsu approx. 10:00; taxi to Koka Ninja Village (30–40 min)
- Koka Ninja Village (2–3 hours)
- Optional: Miho Museum (20 min from Koka by taxi) — world-class collection in a mountain setting designed by I. M. Pei
- Return to Osaka by early evening
This itinerary works with standard Osaka hotel accommodation and requires no overnight stays outside the city. Total daily transit is well under two hours each way.
Practical tips for both day trips
- IC card (ICOCA / Suica): Works on JR and most Kintetsu sections, but not on the Iga Railway. Carry some cash for the Iga Railway ticket.
- Kintetsu limited express: Seat reservation required; reserve at the station or via the Kintetsu app. The supplement is modest (a few hundred yen) and worth it for the comfort on a longer journey.
- Koka on Mondays: The Koka Ninja Village is closed on Mondays. Check the official schedule for additional seasonal closures before departure.
- Peak season fares: During Golden Week, Obon, and year-end holidays, limited express surcharges on Kintetsu and JR increase by approximately ¥200–¥400. Booking in advance is recommended during these periods.
- Luggage: Both sites involve moderate walking on uneven terrain. Large suitcases are better left at your Osaka hotel or in a coin locker at Osaka station.

Summary
Osaka is the most convenient base in Japan for visiting the country’s two primary ninja heritage sites. Iga (90 min via Kintetsu) offers the most historically documented collection; Koka (60–70 min via JR to Kusatsu) offers more hands-on engagement with techniques and equipment. Both are comfortable day trips, and visiting both on consecutive days requires no additional overnight stays outside Osaka.
