Sacramento's Nihon Shogakko was established in 1903 for the children of Japanese immigrant families whose parents worked in the surrounding agricultural fields. It was among the earliest Japanese language schools in the United States, and its first class enrolled fifty-six students. The school operated under the Sacramento Buddhist Church, organized in 1899 and believed to be the second-oldest Buddhist institution in the country. The buildings sat in the heart of what locals called Ofu, or Sakura City -- by the 1920s, the fourth-largest Japantown in the United States. The children attended American public schools during regular hours and came to the Nihon Shogakko afterward, from three to five in the afternoon, to study Japanese history, geography, and language. Some lived at home in Sacramento. Twenty-seven boarded at the school, paying seven dollars and fifty cents per month for their maintenance. The school was not a religious institution in practice; it was a place where children learned to read and write the language of their parents.

In the weeks following the dormitory fire, Sacramento authorities initially arrested two men -- N. B. Coats and John Golden -- on suspicion of arson. Coats confessed under interrogation that he had served as a lookout while Golden set the blaze. But three months later, on July 17, 1923, police in Fullerton arrested Fortunato Valencia Padilla after he set six fires in a single day. Under questioning, Padilla confessed to the Sacramento school fire and to at least twenty-five other arsons across California, thirteen of them targeting Japanese households and Japanese-owned properties. His method was consistent: oil-soaked waste materials taken from boxcar journal boxes. His motive, as reported by newspapers of the time, was racial hatred. He was quoted as admitting satisfaction in burning the homes and buildings of Japanese people, a group toward which he professed open antipathy. Padilla's confession revealed not a single act of violence but a campaign -- fires in Fresno, Stockton, Colton, and Sacramento, stretching from 1921 through the summer of 1923.

Padilla was indicted on first-degree murder charges for the school fire on September 1, 1923. The prosecution sought the death penalty. When the trial began on October 31, the case rested heavily on a confession Padilla had first given to an undercover detective planted in his cell -- a man posing as a fellow prisoner jailed on burglary charges. Padilla later alleged that Fullerton police had beaten him to extract a signed statement, a claim the Orange County sheriffs and city marshals denied. After four hours of deliberation on November 7, 1923, the jury found Padilla guilty and recommended life imprisonment rather than death. Judge C. O. Busick imposed the sentence. Padilla entered Folsom State Prison, where the 1930 federal census recorded him working as a driller in the quarry, prisoner number 13127. He was later transferred to San Quentin. At the time of his death in 1970, Padilla was one of the longest-serving inmates in California -- nearly half a century behind bars for a crime that had taken ten children in a single night.

The dormitory was never rebuilt. Sacramento's Japantown itself would not survive much longer as a distinct community -- urban renewal, wartime internment, and demographic shifts dismantled what fire alone could not. But the Nihon Shogakko continued in other forms: the school that began in 1903 persists today as Sakura Gakuen, still teaching Japanese language and culture to Sacramento's children. The fire of 1923 occurred in an era when anti-Japanese sentiment was not a fringe position but mainstream California politics. The Gentlemen's Agreement of 1907 had already curtailed Japanese immigration, and the Immigration Act of 1924 -- passed the year after the fire -- would shut the door almost entirely. Padilla acted alone, but he acted within a climate that gave his hatred room to breathe. The ten children who died that April night are remembered not with a grand monument but through the quiet persistence of the community they belonged to -- a community that endured the fire, endured the internment camps, and endured the bulldozers of urban renewal to remain, in diminished but living form, part of Sacramento's story.
