What is uncertain
Where the sources disagree
- Disputed: entry into the Jesuits. The Society's biography says 1597; an earlier, unattributed account says 1595, at Amakusa.
- Disputed: year and place of capture. The Society's biography says 1636, in the mountains of Shikoku; the CBCJ says he was caught "in the mountains of Ōsaka" (大坂の山中); the earlier account says 1635, at Ōsaka-tōge in Awa.
- Solid: day of death. The CBCJ list of the 188 (no. 186) gives February 25, 1636, as does the heading of the Society's biography; that biography's text gives February 26 as the day he was condemned.
- Unverified: details from the earlier account that no opened source confirms: the Takatsuki seminary in 1586; the Fushimi church in 1607; preaching to Hachisuka Iemasa and Ashikaga Yoshitane by name (the Society's biography says only "his Ashikaga relatives"); and his dying "three days later".
- Unverified: birthplace Kawachi. The Society's biography gives Tokushima, in Awa.
