Battle ship at the end of the feudal era
Battle ship at the end of the feudal era
Now, we'd overview the history of 'battle ships.' From the very beginning of the Japan's history, the relationship between Japan and China was inseparable.
The ships visited China in the very old time were supposed to be so-called large-ships. But we don't think these ships were the battle ships. Then, about 900 years ago (the end of the Heian (平安) era), several large scale battles were fought near the ocean (e.x. the Battle of Dannoura (壇ノ浦の戦い)). And many ships were used for the battles.
About 600 years ago (the Muromachi (室町) era), several large-ships were made for the international trade between Japan and China.
Moreover, another kind of smaller ships for ocean voyages were produced in Japan near the Korean Peninsula. These ships were used for the piracy. We'd like to call the ships were the first battle ships made in Japan.
According to enlarging of pirate group size, they came to develop the lager ships which were used to take commanders on. Then, the larger ships than 'Kobaya' were made and they were called 'Sekibune (関船).'
These ships had 20 to 30 meters length and the crews were 50 to 150.
And next, navy force people became to think that larger ships had advantages in the situation of navy battles. Then, they invented large ships which were called 'Atakebune (安宅船).' These ships had 30 to 50 meters length and the crews were 100 to 500. In particular, over 50 meters were especially called 'O-atakebune (大安宅船).'
In this era, Japanese battle ships were highly innovated. And numerous naval battles developed innovation, furthermore, famous episodes related with navy were created.
For instance, there was a tale in which Oda Nobunaga (織田信長) invented 'Atakebune' to battle against the Mouri (毛利) group. Because the Mouri group had many pirate subordinates and were assumed to have the dominance in the naval battle fields. So, Oda Nobunaga made 'Atakebune' (enormous sized battle ship) and the Oda (織田) group won the battle.
To our surprise, the parties involved (Japanese war-lords) didn't want to learn the secret of European ships. Why? Maybe, European side avoided to sell ships or instruct technologies, if somebody would have wanted to learn them.
At the end of this era, the civil war was over and Japan was reunited.
The result was kind of tragedy. The opposite also happened. Before this invasion, Korean battle ships had already been fighting against Japanese pirates' battle ships long time. And Korean navy had developed firearms (cannons) to counteract 'Kobaya' (Japanese small scale battle ships). The ability of their firearms were also produced good results against Japan's giant battle ships.
While, Japanese battle ships had no experience with foreign navies. So, Japanese battle ships had added improvements against smaller firearms (matchlock guns) only. Japanese giant battle ships were active if the opposite navy also used matchlock guns.
And also, when Japanese bought cannons, the merchants were Europeans. So, they were rare and expensive. (On the other hand, Korean could buy cannons from China, so they had advantage according to equipment.) Japanese giant battle ships lost their dominance in the naval battle field around Korean coastal area.
Very important incident for the Japanese history happened in 1853. It was the arrival of Commodore Matthew Perry. (He was one of the most famous foreigner of Japan because of the impact of this incident.) Soon after the incident, the order of prohibition of larger size ships was canceled. (The order had notified in 1609.) At the result, Japanese battle ships' production restarted after 244 years.
Perry fleet's action was a business activity to expand their market for USA. On the other hand, for Japanese at that time, it was the changing the status quo by force. So, majority of them couldn't accept Perry's request.
Even though Japanese government had been choosing the closed-door policy, they had information connecting foreign ships. After 1853, because of the prohibition's cancellation they restarted the construction of a battle ship using technology of western countries.
The fact they could construct 'Houo' means they already had the knowledge and capability of constructing western ships. However, 'Houo' was a western style sailing ship but speaking of details, constructing technique of Japanese style ships was used widely. And more than anything, they didn't have the knowledge and capability of constructing steam engine ships.
The first steam engine ship of Japan was 'Kanko (観光)' which had presented from Netherland in 1855. And, it had 53 meters length and 6 cannons, and made in 1850. (Finally, it was demolished in 1876.)
We'd like to introduce the most famous Japanese steam engine ship, 'Kanrin (咸臨).' Japanese government at that time (= the Edo shogunate) bought it from Netherland in 1857. It traveled across the Pacific Ocean by only Japanese crews in 1859.
Purpose of the travel was to exchange an instrument of treaty ratification. And to show the ability of the Japanese navy, they tried the dangerous travel. The ship safely arrived in San Francisco. The Japanese navy could show off the ability of them to the world.
In this period of time, there wasn't a battle between Japanese battle ships and foreign battle ships. But, between Japanese battle ships, happened several times.
For instance, the shogunate battle ships fought against Daimyo's battle ships in 1866. Furthermore, after the Edo shogunate abandoned the government, the remnants of the shogunate stole the battle ships. The remnants' battle ships fought against the new government's battle ships in 1868.
If we talk about what lay ahead at the end of the feudal era, next era was the Meiji (明治). During the Meiji era, the next government prioritized ruling of the ocean around the Japanese archipelago.
During the Japanese-Russo War, a world-famous naval battle happened (The battle of the Sea of Japan). However, it happened after the end of the samurai's era.
We suppose the battle ships' history at the end of the feudal era was the history changing the status quo by foreign force. It was start from zero. So, we think Japanese government at that time was quite good.

Sight words: Shoin
Sight words: Shoin
I couldn't explain the difference of the same name rooms, so, I searched a description paper of the building. The former example is explained as "space for official audiences." The latter example is explained as "soothing space." Then, why these quite different rooms were named same name, "Shoin (書院)" ?

Climbing up Gifu castle
Climbing up Gifu castle
In the first place, mountain castles had been made for the purpose of hiding places. Because lords usually lived in the flat land at that time. And, in the case of emergency such as attacked by enemies, they made quick hide into the mountain castles and fought back against them. The Gifu castle was considered one of such kind of castles.
Oda Nobunaga and his previous castle lord, the Saito clan didn't consider such like this. In their brains, the purpose of this mountain castle was changed from the hideout to the symbol of the ruling. Because the castle site was in the center of an extensive plain and the plain positioned in a strategically important area. And, if they made buildings at the top of the mountain, many people could come to look at the symbol of their ruling.This mountain castle is located at the top of the Kinkazan mountain. So, as we already mentioned, the main castle tower is watchable from all around the plain surrounding this mountain. The fact that the tall mountain such like the Kinkazan (329m) standing in the center of the flat land (13m) consisting the downtown of Gifu city is rare.
By the way, in the Gifu area, there were many castles in flat land and mountain castles in the mountains surrounding this area. These castles weren't ideal to be the castle where the ruler lived. Because castles in the flat land weren't easy to find. People should approach closely if you wanted to see them. And mountain castles in the surrounding mountains of the Gifu plain were also same. These castles' existence couldn't show their dignity to the people who lived there.
For the previous lords of Oda Nobunaga, the role of their castles was to hideout into from the attack of the enemies. And also to endure the attack. So, they didn't make their castles on the assumption that they lived their daily lives. Oda Nobunaga supposedly came up with the idea to live on the top of the mountain castle. And we can't suppose what the residences at the top were like from the records left behind.
We think it's too difficult to climb up and climb down to the top of the mountain oftentimes. Because we experienced climbing to the top by foot. Based on our experience, we doubt the historic fact that Oda Nobunaga lived at the top several years.
The beginning of the Edo period (1603-1867), this castle was dismantled. Then, all buildings in the Kinkazan mountain were removed somewhere. According to an uncertain story, the main tower's wooden parts were used as another castle's main tower. And the main tower's drawing was remained. And the reconstructed main castle tower (1956) was made by reinforced concrete and the exterior was decided referencing the drawing.
What we'd like to deliver is about trails of the mountain. The difference in the height from the foot to the top is over 300 meters. This over 300 meters difference avoid smooth access from the foot to the top. Furthermore, the mountain is quite massive and has a very wide range. Visiting the top on foot is quite an effort.
These trails are maintained as hiking paths now. And the number in this mountain area is 10. Furthermore, the trails having relationships with the Gifu castle are maybe 5. One of the paths is from another side foot, so, 4 paths are mentioned in the paper we handed over at the entrance of the castle.
It connects from the western foot building to the top of the mountain. Once it was the major climbing route of the people who belonged to the castle. At first, the road goes south in a flat area. And from the south entrance, the trail begins to climb. It will take about 60 minutes to the top, according to the information from someone's HP.
There was a stable for horses at the top, and horses lived there might climb this trail. We haven't experienced this trail, so, it's difficult to tell the expression. According to the previous HP, the route is well maintained and it's easy to climb.
B: The Hyakumagari-do(百曲道)
We chose this route regrettably. It also connects from the western foot building to the top of the mountain. It begins to climb from south-west of the mountain. According to the paper we got at the entrance, it seemed a long way. So, we led to poor judgement. Quite many places are rocky paths. However, It will take about 40 minutes to the top, according to the previous HP. It was difficult for us.
Additionally, the HP tells us this trail was used to a suprise attack in the Sengoku era's real battle. And the trail was too steep to move riding horses. (You could've told us earlier.)
C: North route
It also connects from the western foot building to the top of the mountain. It begins to climb from north-west of the mountain. According to the HP, it's the second gentle route and it will take about 70 minutes to the top. North of the castle is the wide Nagara river, so, you can look down and view the scenery of it.
D: Shortcut route
It also connects from the western foot building to the top of the mountain. It begins to climb from the behind of the western foot building. The length of the route is the shortest, but it's too steep to climb quickly. It will take about 40 minutes to the top. And you should skip to climb down this route. It was supposed to be considered as a byway at that time.
🙊🙊 To tell the truth, there is a ropeway to the top. Almost all use it. It's not necessary to climb on foot. However, you may not notice the difficulty that we discovered by this struggling.

L L B C (8) Kyoto Station Building
🗾 L's Life in a Big City (8) 🗾
However, I had information that this station was adjoining a hotel, a department store, a park area and so on. So, I was thinking that I would like to explore this building someday. But until this visiting experiment, this station was only for transportation facility for me.In the midway to the top, the width of the stairs was changed. Upper side of the stairs was very wide and picture perfect. At the end of the stairs, there was a hanging garden. It was 50 meters above the station concourse. From there, there was an air corridor and I admired scenery of the Kyoto Tower.

Tea ceremony rooms in history
The Japanese tea ceremony is world-famous, we believe. Then, how much do you understand the tea rooms where tea ceremonies held? There are many historically famous tea rooms all around Japan. However, we suppose, if we research their current status, they are quite often confusing and behind the screens in a sense. After this introduction, we'll try to describe these of historic tea rooms.
Uraku-en Jo-an (有楽苑 如庵) : National treasure
![]() |
| 如庵 |
This building was built by Oda Urakusai (織田有楽斎) who was a famous warrior and tea master, at the Shoden-in (正伝院) temple in 1618. The Shoden-in temple was a tatchuu (塔頭) temple of the Kennin-ji (建仁寺) in the Kyoto city. ( a 'tatchuu' is a subsidiary temple belonging to the main temple) It's now located in the garden-park named the Japanese garden ' Uraku-en' in the Inuyama city, Aichi prefecture.
Now, you have to understand the unit of area, tatami- 1-jo (畳1帖). Tatami- 1-jo means the width around 90 centimeters by 180 centimeters. And, tea masters at the Sengoku era represented by Sen-no Rikyu (千利休) considered it was necessary to narrow down the width of the tea rooms. For example, Sen-no Rikyu thought the width of tatami- 8-jo which was popular at that time was too wide to exchange guests and master. At first, he made a tatami- 4.5-jo width tea room for his proof theory. Furthermore, he made a tatami- 1.5-jo width tea room in the end.
Against the mainstream, the width of this tea room is 'Ni-jo han daime.' Ni-jo han daime means 2-tatami plus 0.5-tatami plus 0.75-tatami, so, the total width is 3.25-tatami. He didn't choose the extreme narrowness for his tea room. This expression he said is very famous, "A tatami- 2.5-jo width or a tatami- 1.5-jo width will be more a pain than a treat."
Urasen-ke Kan-un-tei (裏千家 寒雲亭) : National important cultural asset, Urasen-ke Kon-nichi-an (裏千家 今日庵) : National important cultural asset, Urasen-ke Dairo-no-ma (裏千家 大炉の間) : National important cultural asset, Urasen-ke Ryu-sei-ken (裏千家 溜精軒) : National important cultural asset, Urasen-ke Yu-in (裏千家 又隠) : National important cultural asset, Urasen-ke Mushiki-ken (裏千家 無色軒) : National important cultural asset
Urasen-ke is a clan or a kinship group which leads the tea ceremony community in Japan. The Urasen-ke residence is located at Kyoto city Kamikyo ward. It was originally made in 1578, and was destroyed by fire in 1788. So, it was reconstructed after the fire, and was experienced building extensions and renovations many times after the reconstruction. Apart from 6 famous tea rooms above, there are so many other tea rooms in it.

| 寒雲亭(鎌倉市) |
The plan is 8-tatami plus 1-tatami-width Tokonoma (床の間), alcove for displaying. It was supposed to be used for large-scale ceremonies. To tell the truth, there is another original at Toukei-ji temple in Kamakura city, Kanagawa prefecture. This building is an individual flat and it has an authentic story such as when they moved, why they earned. So they insist their Kan-un-tei is the genuine (so, Kan-un-tei in Kyoto city is an artificial). The inside atmosphere is so different.
The Kan-un-tei in Kamakura city is displayed by Syoin-zukuri (書院造) style and has kind of formal atmosphere. On the contrary, the Kan-un-tei in Kyoto city is displayed by Wabicha (侘び茶) style and has kind of relaxed atmosphere. We just saw them in pictures, but the impression is quite different.
Urasen-ke Kon-nichi-an (裏千家 今日庵)

| 今日庵 |
Urasen-ke Dairo-no-ma (裏千家 大炉の間)
![]() |
| 大炉の間 |
This tea room was made at the time of the extension in 1856. It's consisted with 8-tatami room and 6-tatami room, so total is 14-tatami in width. At this time, tea rooms were made for other purpose. At first, it was for service by the master to the guest. But then, especially in the Urasen-ke residence, it was for teaching of many apprentices who wanted to learn the ceremony. By this extension, several separate buildings were connected.
So, for example, Kan-un-tei which was separated from the main residence was connected. And, the Dairo-no-ma was made in the center of the complex. They positioned the Dairo-no-ma as the most important tea room of this residence.
Urasen-ke Ryu-sei-ken (裏千家 溜精軒)
Same as the Dairo-no-ma, it was made at the time of the extension in 1856. It's located between one individual room to the next, and it looks like a hallway. But when you close the sliding doors, this space changes a tea room. The room is 6-tatami in width.
Urasen-ke Yu-in (裏千家 又隠)
![]() |
| 又隠 |
Urasen-ke Mushiki-ken (裏千家 無色軒)
The construction date was uncertain, but the planner was the 4th master. (In addition, the most famous Kan-un-tei was planned by the 3rd.) The room is 6-tatami plus 1-tatami size wood floor in width.
Omotesen-ke Shofu-ro (表千家 松風楼), Omotesen-ke Tensetsu-do (表千家 点雪堂) : National important cultural asset, Omotesen-ke Fushin-an (表千家 不審庵)
Omotesen-ke is also a leading tea ceremony community in Japan. The Omotesen-ke residence is also located at Kyoto city Kamikyo ward. However, we couldn't find the information of the residence. Famous tea rooms are mostly young. And also they have only one national important cultural asset. We doubt they hide their history in the veil.
Omotesen-ke Shofu-ro (表千家 松風楼)
Shofu-ro was made in 1921. It has 8-tatami main room, 5-tatami east-room, 4-tatami west-room, and 8-0.75tatami south-room. It's for large scale tea ceremony.
Omotesen-ke Tensetsu-do (表千家 点雪堂)
Tensetsu-do is a 4-tatami tea room made in 1839. It was the renovation of the previous tea room. There isn't enough information in the Internet, so we can't describe its history.
Omotesen-ke Fushin-an (表千家 不審庵)
Fushin-an is a 3-tatami tea room made in 1913. It's also the renovated. And also, there isn't enough information in the Internet, so we don't know the back.
Gyokurin-in Kasumidoko-no-ma (玉林院 霞床の間) : National important cultural asset, Gyokurin-in Sa-an (玉林院 蓑庵) : National important cultural
Gyokurin-in Kasumidoko-no-ma (玉林院 霞床の間)

| 南明庵 |
Gyokurin-in Sa-an (玉林院 蓑庵)
Sa-an is another tea room and 3-tatami in width.
Kodai-ji Iho-an (高台寺 遺芳庵), Kodai-ji Shigure-tei + Karakasa tei (高台寺 時雨亭+傘亭) : National important cultural
Kodai-ji Iho-an (高台寺 遺芳庵)
It was built on the property of the Kodai-ji temple in Kyoto city Higasiyama ward. The building was moved here in 1908. The width is 1.75-tatami tea room and same size Mizuya (washing place). The original was supposed to be made at early times in the Edo period, however, this is more young.
Kodai-ji Shigure-tei + Karakasa tei (高台寺 時雨亭+傘亭)
![]() |
| 時雨亭 |
The floor of the Shigure-tei isn't covered with tatami mats, so, we have difficulty to describe the width of it. The width is around 6-tatami. There is worthy of a special mention that is the location of this tea room. It's on the second floor of a thin building, and the master and the guest have to climb the wooden ladder for the ceremony. We doubt they can hold formally arranged ceremony or not.
And the Karakasa-tei is connected with the first floor of the Shigure-tei by an open hallway. The width is 6-tatami. It was built in the early Edo period. And supposed that originally built on the property of the Fushimi castle and removed here later.
Koho-an Bo-sen (弧篷庵 忘筌) : National important cultural
It was built on the property of the Koho-an (Kyoto city Kita ward), one of the tatchuu temples of the Daitoku-ji. The original was destroyed by fire in 1793. The date of the reconstruction was not clear, but we suppose it was around 1800. It's 12-tatami in width.
Konchi-in Hasso-seki (金地院 八窓席) : National important cultural
It was built on the property of the Konchi-in (Kyoto city Higashiyama ward), one of the tatchuu temples of the Nanzen-ji. It was made by renovating the original one around 1628. Then the renovated one became famous and had the name, "Hasso-seki." It's 3.75-tatami in width.
