Main Event

Ryusendo Cave Festival

Known in the old days as the Shizugawa Shrine Festival, today’s Ryusendo Cave Festival celebrates gratitude for the crystal-clear water springing out of the Cave, while offering prayers for the continuing protection of these water resources – and conveying a spirit of appreciation for the forest that nurtures this gift of water.

The events include a safety prayer ceremony to express gratitude for the purity of Ryusendo Cave’s water, performances of the town’s distinctive folk entertainment, and Mochi-maki (tossing rice-cakes together with noveties among guests).
Being held in the Golden Week, the festival becomes very crowded with throngs of tourists, as well as locals.

Ryusendo Cave Summer Festival

The summer festival’s biggest attraction is its grill which you can enjoy Iwaizumi’s famous specialty – Iwaizumi Tankaku-gyu (Iwaizumi shorthorn beef). The grill is so popular that visitors begin queuing up even before it opens!

Other programs include a special guided tour by a researcher(s) of the Speleology Research Institute, folkloric performances and also live music.
All the while, Iwaizumi Town’s specialties will be sold by the town’s traders.
In recent years, there have been marketing programs such as social networking service (SNS) incentive promotions to encourage visitor referrals to Ryusendo.

Ryusendo Cave Autumn Festival

Jointly organized by Iwaizumi Town’s “Matsutake (pine mushroom) Huts (producer outlets)” and the “Oyster Huts” of Yamada Town, Ryusendo is where you can enjoy these autumnal delicacies.
The town’s other vendors also sell unique autumnal dishes, such as salmon soup and mushrooms.
In addition, the program includes a special guide by a researcher(s) of the Speleology Research Institute, the performances of the folk art/entertainment and also music playing.

In recent years, in cooperation with the Rest House and Café Ponte, we sell specialty products of Iwaizumi and Yamada, and provide special menu dishes.

Ryusendo Cave Winter Events

Early December to late March

We hold a variety of events to draw in tourists in the winter season.
These events are designed with winter’s features, and include collaborative projects involving other organizations and treasure hunting.

Sacred Place for Lovers

Among the nation's sightseeing sites, a romantic spot is specially favoured for marriage proposals is nominated as a ”Lover`s Sanctuary”. Ryusendo Cave and ”Hakkoi-mizu (first love water) and Hyakkoi-mizu (100 love water)” that locates in the nearby Ureira Shopping Street are one of the Lover`s Sanctuary locations.


Enter the Gekkyuden (Imperial Palace) which is a special spot inside the cave. Be sure to turn your head around when you approach the “Mamori-jishi (Guardian Lion)”. This area of the cave you have just passed through looks just like a heart slightly tilted to the left.
This hidden heart spot was made by hanging stalactites quite by chance.


In Iwaizumi, apart from Ryusendo Cave, the water place “Hakkoi-mizu (first love water) and Hyakkoi-mizu (100 love water)” in the nearby Ureira Shopping Street has also been designated as a “Lover`s Sanctuary”.
Please press stamps on your special visitor’s sheet at these two sites. Since these stamps have different patterns, you need to press them both to create a complete picture.

Nameplate monument

When officially authorized, a metal plaque is awarded to the Lover`s Sanctuary.
In the Ryusendo Cave, the plaque has been placed on the dragon wood carving created by one of Iwazumi’s leading chainsaw artists.
The same plaque can also be seen at the water spot, “Hakkoi-mizu and Hyakkoi-mizu”, of the Ureira Shopping Street. Here the plaque is placed in the water, surrounded with stones that shine at night.

Other events

Activities of the Lover`s Sanctuary include couples joining in the Mochi-maki event at festival time, or participating in a chainsaw art demonstration in making a monument for the metal plaque. Also, there are gifts for couples who introduce others to the Ryusendo Cave.
Our Valentine events have seen a number of successful marriage proposals made at the special cave concert or at the surprise proposal opportunities.

Hakkoi-mizu and Hyakkoi-mizu

In Iwaizumi, we say “Hakkoi (or Hiyakkoi)”, meaning “it’s cold!”.
Iwazumi’s famous spring waters are all cold, so it is no surprise that what flows through the waterway in the Ureira Shopping Street is no exception.
The water spot in the Ureira Shopping Street is referred to by the word-play, “Hakkoi-mizu (first love water) and Hyakkoi-mizu (100 love water)”.
This refers to it being a love spot for those seeking not only their first love, but those also wanting many more loves later!
The water spot here, approx. 5 min. by car from Ryusendo Cave, is also designated as a Lover`s Sanctuary.
