At the time of the relocation, 500 to 600 ronin from the former Mogami family gathered together and carried the remains of Yoshimitsu and those who had died with their families to the current Kozenji Temple, and the temple has since been protected by former retainers to the present day
A temple dedicated to the Bodhisattva Memyo, the ancestor of the San
As you proceed along the approach to the shrine, the first thing you see isthe Bodhisattva Ashvaghosha. I thought it was a roadside deity, but the character at the beginning is different... I can't read it. After researching, I found that it's written with the character for "god" above the character for "insect," and it seems to be pronounced "san."
The Bodhisattva Ashvaghosha (馬明) is a bodhisattva originating from Chinese folk beliefs, andthe god of sericulture and weaving. Judging from the characters, the "insect" in "god" might refer to a silkworm. This is just speculation, though...

If you go further, you will come across a magnificent stone bridge in the temple grounds

It is one of the sacred sites of Jizo Bodhisattva pilgrimage in the inland areas of Yamagata Prefecture, including Yamagata, Murayama, Tendo, Sagae, Mogami, Obanazawa, Higashine, and Shinjo, as well as the Mogami and Murayama regions

On the right side of the bridge you can see a magnificent bell tower

Kozenji Temple Main Hall
The front of the main hall. There are no flashy decorations, and it gives a solemn impression

However, there was a magnificent dragon sculpture on the front

For some reason, the Mogami family crest is tilted at a 90-degree angle at the bottom of the pillars supporting both sides. I wonder if there is some significance to this

Kozenji Temple Garden
If you proceed to the back from the left side of the main hall,the "Kozenji Garden"you will see the entrance to

, said to have been created in the early Edo periodthe Enshu styleand covers an area ofapproximately 900 tsubo (about 3,000 square meters). It is designated as a scenic spot by Yamagata City.
The exact year the garden was created and who created it are unknown, but it is said to be one of the oldest gardens in Yamagata Prefecture

Mogami Yoshiaki's grave
If you continue further from the Kōzenji Temple garden,the tomb of Lord Mogami Yoshiakiyou will see

Besides Lord Yoshimitsu's grave, this site also家親公, and Lord Yoshitoshi, the 13th head義俊公contains the graves ofLord Iechika,Sagae Hizen-,Nagaoka Tajima-no-kami, andSagae Jubei.

summary
Thanks to the skills of the Sengoku daimyo Mogami Yoshiaki, the Yamagata domain grew into one of the largest domains in the Edo shogunate, with a 570,000 koku (unit of rice production) yield. However,just nine years after Yoshiaki's deathinvolving his retainers, known as the Mogami Rebellion,disputeresulted in the confiscation of all of their territory.
It truly seems like a story of rise and fall, but the fact that it was such a powerful city can be seen from Yamagata Castle, which was also known as the Kasumi Castle
If you visit the Yamagata Castle ruins or the Mogami Yoshiaki History Museum, be sure to also visit Kozenji Temple
