If you want to take a sightseeing test for the first time in a while, purchase the latest version of "Monoshiri Encyclopedia" and look at the 10th sightseeing test problem of spelling, ask. 52 says, "Beside the Chuo-ku government office annex, there is an explanatory version showing that there was a clan residence of the Tosa clan near Tsukiji 1-2-chome in the late Edo period. It is said that Sakamoto Ryoma, the priest of late Tokugawa shogunate, went to a dojo of a swordsman while sleeping in this clan residence. Who of the following is this swordsman?" That's right.
Indeed, on page 69 of Monoshiri Encyclopedia, "It is said that late Tokugawa shogunate's Shishi Sakamoto Ryoma went to the dojo of Sadakichi Chiba while staying at this clan's residence." If you remember this part accurately, you can easily give a correct answer, but it would be a little difficult to read so carefully. However, only too easy problems will lead to a series of high scorers, and it can be felt that the questions are quite devised.
Regarding this, as I posted on November 25, last year, if you read "Ryoma Goes", you will be able to get the correct answer very easily.

Once again, I quote the relevant part of "Ryoma Goes" (Ryotaro Shiba is described as "Chiba Sadayoshi").
"Ryoma was moved from a clan residence in Kajibashi to a clan residence in Tsukiji. In addition to Ryoma, most of the Wakai clansman were moved to two lower houses in Tsukiji and Shinagawa. This is one of the Tosa clan's defenses in preparation for the invasion of Kurofune Edo Bay. While the number of people was stationed at these two seaside mansions, they were building a Daiba in Shinagawa with the permission of the Shogunate. " (Bunshun Bunko Volume; Page 169)
"``````````````````` After all, in order to make a great success, it is better to learn a great style. For that, the Kitashinichi sword style is good. "Oh, don't you be a teacher of Shusaku Chiba." The Xuanwu-kan in Chiba is said to be the three major dojos in Edo, along with Shunzo Momoi on the banks of Kyobashi clams and Yakuro Saito in Kojimachi, and divided the swords of the world into three parts. "... It's best to learn from Mr. Shusaku, but since he's already in old age, it's good to be used by Mr. Sadayoshi, his younger brother who has a dojo in Kyobashi Okemachi. Sadayoshi's dojo is called Kochiba against Otamagaike Pond's Ochiba." (Bunshun Bunko 1 volume; page 18)
