However, their efforts proved fruitless, as the force of the water was extremely violent, and at around 4:20 in the afternoon, a breach of over 100 ken occurred. The flood instantly swept over the paddy fields of Matsuda Sōryō in Matsuda Village, rushed south along the embankment of the Tōkaidō Railway, inundating all of Kaneda Village, while the area around Ōsawa in Soga Village, Soga District, came to resemble a vast river. The backwash extended to Kaneko and Miyaji, flowing through Ōi and Shimo-Ōi in Soga Village, then to Ōi, before flowing southward through Ōtomo in Kamifūchū Village, Ashigarashimo District. After sunset, the rainfall grew increasingly intense, turning into a violent windstorm by around 9 o'clock, which damaged two or three sections of the railway embankment, causing considerable damage to the farmlands of the region. During the night, the rising waters grew ever more severe, destroying the embankment at Kamiyama in Matsuda Village and the bridge between Kamiyama and Matsuda Sōryō. Furthermore, in Narita, Toyokawa Village, more than 60 houses were flooded and several dozen chōbu of farmland suffered damage, with road and bridge damage reported at several locations along the Fuji Road and Matsuda Road. On the Sagamigawa River's Kaname River route, approximately 40-odd ken of the prefectural road to Hadano and the embankment at Shimo-Ōtsuki Futatago, Daikon Village, collapsed and one bridge was damaged. On the Tamagawa River route, the water gauge at Miyuki Village, Tachibana District, Musashi Province recorded a rise of 8 shaku 8 sun, but fortunately there appeared to be no damage.
Based on a report submitted at 6 a.m. on September 11th from the Aikō District Chief to the prefectural governor, 20 ken of the embankment at Atsugi-Kawakami-chō on the Sagamigawa River, and 120 ken between Izachi Village Kumaga-zaki and Sekiguchi, breached, causing 3 farmhouses in Izachi Village to be washed away. Additionally, 1 chōbu of farmland was lost to flooding, with several dozen bu of farmland becoming waterlogged. A report from the Matsuda Police Station also stated that the Kawane River, a tributary of the Sakawa River, flooded again, destroying the bridge-protection embankment at Kawane River, resulting in the suspension of Tōkaidō railway service between Kōzu and Matsuda.
**Suspension of Train Service between Kōzu and Matsuda**: The Kawane River, a tributary of the Sakawa River, once again flooded, causing the collapse of the bridge-protection embankment along the Kawane River. This led to the destruction of over 30 ken of the Tōkaidō Railway embankment, and from 4 a.m. on the 11th, train service between Kōzu and Matsuda was suspended.
According to subsequent reports, embankments at Nakazōne Village along the Sakawa River route—34-35 ken at one location, 30 ken at another—and 60 ken at Tako Village's embankment all collapsed, causing damage to farmland in the villages of Tominaga, Nakazōne, Iidaoka, Renshōji, Imai, Amaiiro-mura Ikada and others, with a total affected area of approximately 100 chōbu. More than half was exposed to the violent current, meaning not only would there be no harvest,

but the land would be filled with sand and silt, likely rendering it barren wasteland.
A report from the Odawara Police Station on the same day stated that the embankment of the Ōi River had been destroyed and several villages in Ashigarashimo District were flooded.
On the Tamagawa River route, the water rose by over 1 jō 1 shaku, destroying 20 ken each of the embankments at Higashi Kōchi and Naka-Shinden in Takatsu Village, Tachibana District.
On the Sagamigawa River route, a telegram on the 12th from Aikawa Village office in Naka District to the prefectural office reported that 20 ken of the Toda embankment in the same village had been destroyed and civilian residences were in danger.
According to a report from the Mamizo Police Branch Station in Kōza District along the Sagamigawa River, the water level rise in Tōma, Mamizo Village, in the same district reached approximately 1 jō 2 shaku, at one point rising high enough that boats could be moored in the gardens of houses. The same village and Tana Village immediately sounded alarm bells, assembled villagers, and defended the embankment. The damage sites in the same district were as follows:
- In Ōsawa Village, Ōshima, small district of Shimo-Ōshima: embankment destruction of approximately 150 ken
- Mamizo Village Tōma: embankment destruction of approximately 100 ken, water rise of approximately 1 jō 1 shaku; 2 houses damaged at the same location; approximately 3 tan of wasteland and riverside fields in Shimo-mizo, Mamizo Village washed away; approximately 10 chōbu of flooded farmland; on the road near Sakai, Toyokawa Village, Naka District along the same river route, water leaking from the Sagamigawa formed almost a violent current, making passage extremely difficult; attempts to set up a ferry were made but no suitable boat was available, resulting in a road closure; the entire town of Atsugi was flooded and roads turned into waterways; all upstream traffic in the town was halted and communication cut off; the maximum water level at that location reached 1 jō 5 shaku 5 sun.
Also, according to a telegram from the Odawara Police Station on the 10th, two sections of the embankment at Renshōji, Tomimizu Village along the Sakawa River were cut, and all nearby houses suffered water damage.
The Sakawa Bridge, which carries the Odawara Horse-Tram Railway line, had one bridge pile washed away at the center of the bridge at around 4 a.m. on the 12th, but fortunately the bridge girders and rails remained intact, so emergency repairs were immediately carried out to ensure that pedestrian passage was unimpeded.

**Flood Damage in Chiba Prefecture**
**Flood Damage in Chiba Prefecture** (Based on notification from Chiba Prefectural Office): Due to consecutive days of sudden showers compounded at times by southeasterly winds, the Edogawa and Tonegawa Rivers in the prefecture suddenly rose, with the water level at Sekijuku Town, Higashi-Katsushika District, at the head of the Edogawa on August 9th reaching 15 shaku. The water continued to rise, reaching 12 shaku 4 sun at Matsudo Town in the same district along the same river route on the 10th, and 28 shaku 8 sun along the Tone Canal. Also, on the 9th, the water at the lower Tonegawa River route at Kioroshi Town, Inba District, reached 15 shaku; at Agui Town, Shimo-Habu District, 14 shaku; and at Nohara Village, Inba District, 15 shaku. By the morning of the 10th, the water rose further to 16 shaku 7 sun at Kioroshi Town, 15 shaku 5 sun at Agui Town, and 16 shaku 6 sun at Nohara Village. Despite prefectural officials, district clerks, and police officers encouraging the local people and working day and night to prevent flooding, the force of the water was too powerful to resist, and eventually numerous breaches occurred, resulting in extreme devastation. The locations were as follows:
- Edogawa River route, Higashi-Katsushika District, Shinkawa Village, Shimo-Hanawa embankment breach: over 25 ken
- Same district, Shichifuku Village, Iwana embankment breach: over 30 ken
**[Left Page, Lower Section]**
- Same village, Zaishō-Shinden embankment breach: over 40 ken
- Same district, Kawama Village, Higashi-Kanai breach: 1 location, length unknown
- Middle Tonegawa River route, same district, Futagawa Village, Furuuchi embankment breach: over 45 ken
- Same district, Fukuda Village, Kinokizaki breach: 2 locations, length unknown
- On the same river route, in Nami-Soma District, Fusé Village, Fuse; Abiko Town, Aoyamachi — one location each; Higashi-Katsushika District, Asahi Village, Mefuki — two locations; Lower Tonegawa River route, Inba District, Nohara Village — one location, approximately 100 ken; same district, Kioroshi Town — one location; Katori District, Kozaki Town — three locations; breaches, length unknown
In addition to the above, due to flooding, one-third of all houses in Nagareyama Town, Higashi-Katsushika District, were inundated. On the lower Tonegawa River route, many houses in Fusa Town, Nami-Soma District, were flooded due to water overtopping the embankment. The breach of the Furuuchi embankment caused the floodwaters to reach Sekijuku Town, inundating over 800 houses in the town and Futagawa Village up to the eaves. Although there were no casualties among people or livestock, the sudden showers had not yet stopped, the water continued to rise, and there were numerous dangerous points along the embankments of both rivers, all currently under defensive measures. This flood occurred while the aftereffects of the July floods had not yet subsided, making this a second major flood, so embankments everywhere had countless cracks and collapses, making defensive measures extremely difficult.
A subsequent report was received as follows:
- Edogawa River route, Higashi-Katsushika District, Fukuda Village, Kinokizaki embankment: 2 locations breached, length unknown
- Same river route, same district, Mabashi Village, Mondo-Shinden embankment breach, length unknown (damage extended to a 25-village cooperative, over 17,000 koku)
- Middle Tonegawa River route, Higashi-Katsushika District, Fukuda Village, Kinokizaki embankment: 2 locations breached, length unknown
- Lower Tonegawa River route, Katori District, Yonezawa Village, Ōnuki embankment breach: length over 15 ken
- Same river route, same district, Kozaki-Jinjuku embankment breach: length unknown
- Same river route, same district, Kanaetsu Village, Jūsankendo embankment breach: length unknown; damage extended to a 104-village cooperative of Chiba and Ibaraki Prefectures
- Middle Tonegawa River route, Nami-Soma District, Kohoku Village, Nakatōge embankment breach: length unknown
- Inba Lake flood-protection embankment, Inba District, Usui Town, Kakurai embankment breach: length unknown
- Damage area, flooded houses, etc. at all above locations currently under investigation. No casualties among people or livestock.
The prefectural office dispatched Inspector Kawamura on the 10th, and at dawn on the 12th sent out department officials, police inspectors, and over ten constables. Upon receiving news of the flooding on the 8th, dozens of technical officials had already been dispatched to key locations, while district clerks, local police station chiefs, and constables were all engaged in flood prevention work.
