愛知ディープ探訪 ~八丁味噌と家康の面影が息づく岡崎を巡る

Okazaki City, located in the Mikawa region of Aichi Prefecture, is famous as the birthplace of Tokugawa Ieyasu, and is a city where the "Hatcho Miso" culture that is deeply rooted in the three Tokai prefectures (Aichi, Gifu, and Mie) is strongly present. On this trip, we visited historical sites related to Ieyasu and toured the Hatcho Miso storehouse. We also enjoyed local delicacies such as misokatsu and miso stew. We also spent some quiet time away from the hustle and bustle at Okudono Jinya on the outskirts, and experienced the deep charm of Okazaki.

Okazaki, the town that raised Ieyasu, is a journey along the Vista Line to experience the "beginnings" of the warlord

In the recent history boom, some people may think of "Okazaki" when they hear about Tokugawa Ieyasu. This place is the "starting place" of Ieyasu, the ruler of Japan. It is the "origin" that is essential to the story of his life.
Ieyasu was born in Okazaki Castle in Mikawa Province in 1542. Born in the age of warring states, he had a turbulent childhood, but his path to unifying Japan began in Okazaki. Even after he moved his base to Edo, it is said that his affection for Okazaki never faded throughout his life.

First, head to Okazaki Castle Park, where Okazaki Castle stands. This is a place of relaxation for the locals, and a historical park where traces of Ieyasu remain everywhere. There are many sights related to Ieyasu within the park, and it is also known as a good luck spot.
Okazaki Castle is well-maintained and can be visited comfortably by people of all ages. It retains its dignity while being friendly to everyone, allowing you to experience the history and culture of Okazaki.
Okazaki Castle is also known as "Dragon Castle." The name comes from many legends related to dragons. One of them is that when they first tried to build a castle on this site, a dragon living in an old well appeared and told the people to worship him as the dragon god, before disappearing after being showered with water gushing from the well. Another legend says that on the night of Ieyasu's birth, black clouds swirled above the castle, and a golden dragon appeared, calling the wind. The dragon is considered a symbol of the protection of Okazaki, and the city emblem is designed with a dragon's claws clutching a jewel.
At the Toshogu Shrine "Ryujo Shrine" inside the castle, pay attention to the ceiling of the worship hall. There you can see a majestic wooden dragon measuring 4 meters in length and 2.5 meters in width. The impressive carving, which is embodied in the craftsman's skill down to the smallest detail, is just like a guardian deity watching over this land. Why not visit Okazaki, the city of dragons, and receive some good luck?
If you want to take a break in the park, head to the restaurant "Ichikawa." The matcha parfait with Ieyasu as its motif is a local sweet with an eye-catching helmet-shaped cookie. It is a dish associated with Ieyasu that gives you a taste of the romance of the Warring States period.

Daiju-ji Temple, a must-see when visiting Okazaki, is the family temple of the Tokugawa clan, built by Matsudaira Chikatada, the fourth head of the Matsudaira clan. After being defeated in the Battle of Okehazama, Ieyasu barely made it back to Okazaki and decided to commit suicide at this temple, but was saved by the words of the head priest and dissuaded.
Later, Ieyasu's ninth son, Tokugawa Yoshinao, the first lord of Owari Nagoya, donated a life-sized memorial tablet in memory of his father. Today, the Treasure Museum (fee required) is lined with memorial tablets of successive shoguns, from the first Ieyasu to the 14th Iemochi, and is a must-see. It is a memorable place as the place where Ieyasu made up his mind to face his destiny.

The "Vista Line" in the title refers to the view that stretches in a straight line for about 3km from Daiju-ji Temple to Okazaki Castle. During the reign of Iemitsu, when the temple complex of Daiju-ji Temple was being developed, it was designed so that Okazaki Castle could be seen from the center of the main hall, mountain gate, and main gate. It is still carefully preserved as a view associated with Ieyasu.

Please take a walk through the town of Okazaki, where history and modernity blend seamlessly together, tracing the areas associated with Ieyasu.

The 400-year story of Hatcho Miso told through giant wooden barrels

When walking through the town of Okazaki, you might suddenly notice a fragrant aroma that makes you stop in your tracks. The aroma wafting through the air is that of "Haccho miso," a traditional flavor nurtured by the climate of Mikawa.
Hatcho miso is made in Hatcho-machi, Okazaki city. The name comes from the fact that it was made in "Haccho Village," about 870 meters west of Okazaki Castle.
Located between the Yahagi River and the Sugo River (Otsu River), Hatcho Village flourished as a key waterway transport point. With high humidity and an environment suited to the long-term aging of miso, and with salt being easily available, it was the perfect place for making miso. Raw materials and finished products were also actively transported by boat along the river.

Two long-established miso breweries in this area, which have been in business since the Edo period, continue to uphold traditional methods to this day, using only soybeans and salt, and aging the miso slowly in wooden barrels for two summers and two winters (more than two years) to create a unique flavor.
I went on a tour of one of the miso breweries, "Kakukyu." You can participate in the tour without making a reservation on the day (reservations are required for groups).
Kakukyu was founded in the early Edo period. Even today, the miso is brewed using traditional methods and aged using weights placed on stacked stones. The cone-shaped river stones apply even pressure to the miso, allowing it to ripen slowly over time.
Another feature is the use of wooden barrels, which are now rare. The microorganisms that live inside the barrels promote gentle fermentation, giving the brewer a complex, mellow flavor.
During the tour, you can learn about the history of Hatcho miso, the manufacturing process, and the tools used by the craftsmen with the help of a guide. At the end, you can also try miso soup and konnyaku dengaku made with Hatcho miso.
At the restaurant "Okazaki Kakukyu Hatchomura" on the premises, you can enjoy dishes such as misonikomi udon and miso katsu, and you can also purchase souvenirs made with Kakukyu's miso at the shop. The soft serve ice cream made with miso powder is a unique dessert that can only be found here, with a creamy texture and a strong miso flavor.
I wanted to enjoy Hatcho miso to the fullest, so I decided to go on a gourmet tour. I'll tell you about that in the next chapter.
