78.Marugame Castle Part2

Great stone walls, great view and the remaining Main Tower

Features

Today, Marugame Castle is open to the public as Marugame Castle itself or the Kame-yama Park. The range of the park is inside the Inner Moat. When you stand in front of the moat, you would be surprised to see the amazing high stone walls with the remaining Main Tower on them. The high stone walls are about 60m which is said to be the highest stone walls among other multiple tiers in Japan. (the highest in single tier is the stone walls of Osaka Castle which is about 33m high).

From Main Gate to Third Enclosure

Visitors usually enter the castle through the remaining Main Gate after crossing the bridge over the moat from the north. This gate has a typical defensive gate building style called Masugata. It consists of a square space surrounded by two gate buildings, mud walls, and stone walls.

Then, you will walk up on the long steep slope called Mikaeri-zaka or the Look-back Slope to the eastern direction. On the way of the slope, you will see the highest single tier stone walls in this castle which is 22m high of the Third Enclosure. In particular, the corner of the stone walls is very beautiful called the Slope of a Folding Fan which means its lower part is not steep, but its upper part becomes vertical.

You will eventually arrive at the eastern part of the Third Enclosure. You can see a great view of the Sanuki-Fuji from the ruins of Tsukimi-Yagura or the Moon Watching Turret.

You will finally enter the Main Enclosure at the highest in the castle. A 360-degree view from there is so great. You can see not only the Sanuki-Fuji but also the islands and the Great Seto Bridge on Seto Inland Sea.

Devised Remaining Main Tower

The enclosure now has only the Main Tower, one of the twelve remaining main towers in Japan. It is a kind of three-story turret and, in fact, the smallest one among the twelve main towers.

However, it was improved in some points to look bigger than it is when looking up it from the foot of the mountain. The first point is the reduction rate to the top of the tower is relatively large. The second one is that the decorations of the tower like the hip-and-gable roof and the Chinese styled gable are facing outside. They help the Main Tower looks big from below.

You can also enter the tower and may feel it was made practical as a turret. The steps to upstairs are very steep. It equips machicolations and loopholes for battles. It also exhibits the historical explanation and miniature model of the castle now.

78.Marugame Castle Part1

A castle covered with great stone walls with advanced technology

Location and History

It starts as Branch of Takamatsu Castle

Marugame Castle was located on a mountain called Kame-yama which means tortoise mountain in the western part of the Sanuki Plain of Sanuki Province (what is now Kagawa Prefecture). The part of the plain has several mountains that stood out like a projection, for example, Ino-yama Mountain is known for its beautiful appearance as Sanuki-Fuji. Kame-yama Mountain is one of the mountains and much lower than the Sanuki- Fuji ( 66m vs 422m), but was more convenient for the warriors to build a castle on it.

The Sanuki- Fuji

It is said that the Nara Clan first built a fortress on Kame-yama Mountan, but a castle named Marugame Castle was built on the mountain by the Ikoma Clan in 1597. The Ikoma Clan governed Sanuki Province under the Toyotomi Clan and the Tokugawa Shogunate later between 1587 and 1640. Marugame Castle was a branch castle of Takamatsu Castle which was the home base of the Ikoma Clan. However, Marugame Castle was once abandoned in 1615 in accordance with the Law of One Castle per Province by the Tokugawa Shogunate. The castle had unfortunately been destroyed as we found the wreckage of the old stone walls when the excavation was done.

Rebuilt by Yamazaki Clan and Kyogoku Clan

After the Ikoma Clan was transferred to another due to their internal trouble in 1641, the Yamazaki Clan was given the western part of Sanuki Province by the Tokugawa Shogunate. The Yamazaki Clan was allowed to rebuild Marugame Castle for their new home base. They built the high stone walls with three tiers covering all around Kame-yama Mountain. The stone walls were also built with advanced technology and very valuable because building a new castle was basically not allowed at that time. The re-construction continued for 30 years. The Yamazaki Clan was unfortunately fired by the Tokugawa Shogunate in 1657 during the construction because they had no successor. The Kyogoku Clan following the Yamazaki Clan completed the construction building the Main Tower by 1663.

It looks like Stone Fortress

The final appearance of Marugame Castle was as the following. The Main Enclosure, the Second Enclosure and the Third Enclosure were on the mountain. All the enclosures were surrounded by the stone walls making the very high ones stick together. The Main Enclosure, which was at highest, had the Main Tower and the four Corner Turrets connected with the roofed passages called Tamon or the mud walls. The Second and Third Enclosures were below the Main Enclosure and they also had several turrets. The Inner Moat surrounded the mountain, the Main Gate was just inside the moat in the north, and the Back Gate was in the south. In addition, warriors’ houses were built outside the Inner Moat and were also surrounded by the Outer Moat.

The Kyogoku Clan governed Marugame Castle and the Marugame Domain until the end of the Edo Period. In fact, the lord of the castle lived in the Main Hall at the foot of the mountain. That was a common way for the lords of the castles in peaceful time. Anyway, Marugame Castle must have looked like a stone fortress.
