Birthplace of the Ninja

Koka (甲賀市; -shi) is a landlocked city in southeastern Shiga Prefecture, on the border with Mie Prefecture.

Home of the Koga ninja (actually pronounced "Koka") and Shiga's second largest city in area, Koka was formed in Oct. 2004 with the merger of Koka, Minakuchi, Shigaraki, Tsuchiyama, and Konan towns. These former towns are distinct geographical, cultural, and historical areas each having its unique attractions.

Although it does not face Lake Biwa, the city is spread far and wide with diverse sights such as Shigaraki pottery, Ninja houses, Minakuchi Castle, major festivals, and Tokaido Road post towns Minakuchi-juku and Tsuchiyama-juku.

The JR Kusatsu Line and Ohmi Railways are the main ways to reach Koka.

Minakuchi Hikiyama Matsuri Koka Ninja Village Tsuchiyama-juku

  • Koga-ryu Ninjutsu House 甲賀流忍術屋敷 - Koka has a ninja house open to the public. This one is more authentic since it remains at its original location. Built in the 17th century and originally the house of Mochizuki Izumonokami, the leading ninja clan among the 53 Koga ninja clans. With a thatched roof, the house looks like any ordinary 17th century house on the outside, but inside it is equipped with trap doors, swinging walls, etc., to help the occupant elude any intruders. The house also exhibits ninja weapons and artifacts. And the gift shop sells ninja stuff. The house is 2 km from Konan Station on the Kusatsu Line. Open 9:00 - 17:00, closed Dec. 27-Jan. 1. Admission 600 yen for adults. Phone: 0748-86-2179 Address: 甲賀市甲南町竜法師2331 Web site Map
  • Koka Ninja Village 甲賀の里 忍術村 - Koka is known historically as a town of the Koga ninja, one of Japan's two ninja schools. As a tourist attraction (and theme park), the Ninja Village offers a good sampling of ninja history, technique, and demonstrations. See a ninja house with trap doors and other trickery and a ninja museum exhibiting the world's largest collection of old ninja clothing, throwing knives (shuriken), and ladders. There are facilities for you to try out ninja stuff as well. Throw shuriken at wooden targets, walk on water, and climb walls. Like a real ninja village, this ninja theme park is hidden away in a secret place, not visible from the road. If you don't have a car, take the Kusatsu Line to Koka Station and get out the North exit. Call 0748-88-5000 and ask for a free ride to the Ninja Village. It will take 15 min. (It's actually best to call them at least 15 min. before you arrive so they will be there when you arrive at the train station.) Open 10:00 (sometimes 9:00) - 17:00, usually closed on Mon. Admission 1,000 yen for adults. Web site Map
  • Minakuchi-juku and Minakuchi Castle 水口城 - Following Tsuchiyama-juku, Minakuchi-juku was the fiftieth of the fifty-three stations of the Tokaido Road. The most prominent remnant is Minakuchi Castle. A moat, stone walls, and a reconstructed turret are all that remains. The turret serves as the Minakuchi Castle Museum. Modeled after Nijo Castle in Kyoto, the original castle was built in 1634 as a rest place for shogun Tokugawa Iemitsu during his travels to and from Kyoto. But the shogun stayed at the castle only once. It later became the castle of the Minakuchi clan in 1682 headed by Lord Kato Akitomo. Open 10:00-16:00. Admission 100 yen. Short walk from Minakuchi Jonan Station on the Ohmi Railways Line. Phone: 0748-63-5577 The Honmaru (main keep) is now the sports ground for Minakuchi High School. Minakuchi-juku also has a few post town-related sites like Minakuchi Shrine and Daitokuji Temple. Map
  • Tsuchiyama-juku 土山宿 - Following Sakanoshita-juku in Mie, Tsuchiyama was the 49th post town on the old Tokaido Road connecting Edo (Tokyo) and Kyoto. It is right after Suzuka Pass on the Suzuka mountains, one of the two most difficult sections of the Tokaido. Travelers thus were happy to see Tsuchiyama. Nicknamed "Ai no Tsuchiyama," the town is working hard to preserve its old buildings. A few remnants of the town remain such as the Tsuchiyama Honjin 旧土山本陣 which was the town's exclusive lodge for traveling warlords during 1634 to 1870. The former lodge still has the Jodan-no-Ma room where the daimyo stayed. Shogun Tokugawa Iemitsu and Emperor Meiji lodged here. (Admission 300 yen. Reservations required for visits. Call 0748‐66‐0007.) Also visit the Tsuchiyama Tokaido Museum 東海道伝馬館 showcasing the history of Tsuchiyama and the Tokaido Road. It's modeled after a wholesaler's shop. (Museum open 9:00 - 17:00, closed Mon. and Tue., free admission, Phone: 0748-66-2770). From JR Kibukawa Station, take the Aikuru Bus to Ohmi Tsuchiyama Station (20 minutes). Map
  • Miho Museum - Designed by I.M. Pei, this spectacular museum is quite out of the way in Shigaraki, but well worth a trip. Its collection includes ancient art from Egypt and China. Opened in 1997, the museum is operated by a religious organization called Shinji-shumeikai headquartered in Shigaraki. Admission 1,000 yen for adults. Open 10:00-17:00, closed Mon. and winter months. Take the Teisan Miho Museum bus from JR Ishiyama Station in Otsu, taking 50 min. From Shigaraki Station, 20 min. by car/taxi. Phone: 0748-82-3411 English Web site Map
  • Rakuyaji temple 櫟野寺 - In the Koka-cho area, Rakuyaji temple's main Hondo hall has Japan's largest statue of a seated Kannon Buddha with 11 faces. 500 yen admission fee to enter the main Hondo hall (open 9:00 am - 5 pm, till 4 pm in winter). 日本最大坐仏十一面観音菩薩 Map
  • Kusuri Gakushukan Medicine Museum くすり学習館 - New museum showing the history and culture of medicine making in the Koka area which was rich with medicinal herbs. Hours: 9:30 am - 5 pm, closed Mon. (open if a national holiday and closed on Tue. instead). Across from Kafuka Yume no Mori park. 20-min. walk from Koka Station. Phone: 0748-88-8110 Map

Event Calendar

  • Last Sun. in March - Tsuchiyama Saio Gunko Procession あいの土山斎王群行 is a reenactment of the Saio Princess procession in Tsuchiyama, from Ono Elementary School to Tarumi Tongu. The Saio princess was an unmarried, young Imperial princess, often the Emperor's daughter, who was appointed (by divination) to be the High Priestess of Ise Grand Shrines in Mie Prefecture from the 7th to 14th centuries. For about 660 years, over 60 Saio princesses served at Ise Grand Shrines. A new Saio princess was appointed each time there was a new emperor. She traveled from Kyoto to her Saiku palace near Ise Grand Shrine. The journey took 5 nights and 6 days, and passed through Shiga Prefecture including Tsuchiyama. The procession has the Saio princess and ladies in elegant Heian Period costumes. The festival is from 11:30 am to 4 pm. Map
  • April 19-20 - Minakuchi Hikiyama Festival 水口曳山祭 has a few ornate Hikiyama floats pulled through town. On the first day, the floats are lit up with paper lanterns from 7 pm in their respective neighborhoods while Minakuchi-bayashi festival music is played. On the 20th, at 9 am, the floats are paraded through the streets as they head toward Minakuchi Jinja Shrine (near Minakuchi Jonan Station). Portable shrines also make their way to the shrine. During midday, ceremonies are held at the shrine. At 2 pm, a procession of Chigo children and portable shrines leave the shrine. At 7 pm, the Hikiyama floats leave the shrine. Map
  • May 3 - Kenketo Odori Dance ケンケトおどり - Held at Takigi Shrine 瀧樹神社 in Tsuchiyama from about 1:30 pm. This is a dance performed by eight boys age 7 to 12 at the shrine to ward off natural disasters. They wear a distinctive costume including tall peacock feathers on their heads. The dance is designated as a National Intangible Folk Cultural Property. From Kibukawa Station's North Exit on the JR Kusatsu Line and Ohmi Railways, ride the Aikuru Bus for about 30 min. and get off at Higashi Maeno 東前野. Walk for 5 min. toward the river. Buses leave once an hour. Bus schedule here. Map
  • Fourth Sat. in July nearest the 23rd - Shigaraki Fire Festival 信楽火まつり - Held annually on the fourth Sat. of July closest to July 23. It is a torch procession of 700 people (including children) who carry wooden torches on their shoulders from Shingu Shrine (新宮神社) to Atago Shrine on a hill and ending at the parking lot of the Shimin Center. The festival starts at 7 pm and the route is about 2.4 km long, taking about 50-60 min. From 9 pm, they shoot fireworks. The festival is held to give thanks to fire (for use in pottery kilns, industry, everyday life, etc.) and to pray for fire safety. Shingu Shrine and the Shimin Center is near Shigaraki Station.

Travel Tips

  • Kibukawa Station is Koka's hub for train transportation. Although there are no sights around Kibukawa Station, it is where you can catch the Ohmi Railways to Minakuchi, Shiga Kogen Railways to Shigaraki Ceramic Park, or go further to Koka Station to see the Ninja Village. Local buses also stop at this station.
  • If you are traveling from northern Shiga or coming from Tokyo and want to visit Shigaraki or Koka Ninja Village, it is faster to take the Biwako Line to Kusatsu Station and transfer to the Kusatsu Line rather than riding the Ohmi Railways. If you want to visit Minakuchi, you could take the Ohmi Railways from Maibara Station.
  • On Sat., Sun., and national holidays, the Ohmi Railways "1 Day Smile ticket" is available for only 880 yen and you can use it to ride the Ohmi Railways all day. A good deal if you plan to ride the Ohmi Railways train at least twice.
  • Current weather warnings/advisories for Koka here (Japan Meteorological Agency).

  • Koka was home to one of Japan's two ninja schools. Ironically, Koga ninjutsu is no longer practiced in Koka. It is not considered as a martial art like karate or judo. The other is in Iga-Ueno in neighboring Mie Prefecture.
  • By 2008, about 2.8 million tourists visit Koka annually. About half of them visit Shigaraki, the city's most popular tourist destination. During Jan.-June 2008, 750,000 tourists visited Shigaraki, followed by 330,000 visiting Tsuchiyama. The least visited area was Konan-cho, ancestral home of the Koka ninja. Only 80,000 bothered to drop by.
  • An area and train station in Koka known as Kounan 甲南 (also spelled Konan) is easily confused with Koka's neighboring city of Konan 湖南.
