The Residential house of Hachirouemon Mitsui, located inside the Edo Tokyo Tatemono-en, in Koganei City, Tokyo, was originally built in Kougai Town (now Nishi Azabu 3 Chome, Minato-ku), in 1952.
The house has a guest room, dining room, kitchen and service room on the first floor and a bedroom, bath room and butsuma room, the room where the family Buddhist altar is placed, on the second floor.
The house, in its original location was burned down during the war. To restore it, many rooms, building materials and stones were transferred from other Mitsui family houses located around Japan. The guest room, transferred from Kyoto, was built in 1897 and kitchen and warehouse were from Meiji period.
The guest room has a carpet with a table and chairs rather than the Japanese style tatami mattress, and its ceiling is decorated with craftwork called “sensai” which is made with colored threads and silk. Above the stairway is a luxurious and rare Czech glass chandelier. The handles of the sliding doors of the butsuma room are made of turquoise colored Shippou-yaki or Cloisonné ware.
     The house is filled with a harmonious blend of Western and Japanese styles and visitors can enjoy the quintessence of the Mitsui family’s opulent life-style from the Edo, Meiji and Showa periods.

The Shibukawa Merchant House comprises into one inn the shops, houses and warehouses of the largest seafood merchants in Aizu. The Shibukawa Merchant House used to be a large shop which sold seafood.

Today, the floors have absolutely no trace of dust anywhere and are always polished till they shine, in order for customers to feel at home. There is a room in the annex named 'Room of Patriotism' where the uncle of the late owner, Zensuke Shibukawa, spent his boyhood. In business since the early Meiji period, in addition to the Shibukawa Family, more than 50 servants lived in the mansion at the height of its prosperity.

Many locations for sightseeing such as the Amida Temple can be found in the vicinity. There are many activities for visitors, such as taking a stroll through the streets that had prospered during the Meiji and Taisho periods. These streets still retain their 'Taisho Roman' atmosphere, allowing visitors to enjoy the feeling of slipping back through time.

Running from the moat of Hikone Castle to Kyobashi bridge there is a straight road that goes over the old Middle moats within the castle grounds.

This road reflects the tradition of this castle town, with its black latticed windows, wing walls, white walls and eaves. While the area has been carefully protected, the people's lives are not so visible, such as along the area known today as Old New Town, Yumekyobashi Castle Road.

Honmachi, in Hikone, where this street is located, became a castle town in 1603 at the same time as Hikone Castle was completed. The historical town has 6-meter-wide roads, giving a taste of the past.

In 1985, city planners commenced renovation of this road, realising its historical importance. In 1999, renovation and repairs were completed and the Honmachi area was reborn as Yumekyobashi Castle Road.

The road has been decorated with images of Hikone 'karuta' (local playing cards), which lend an extra tasteful element to the road as you walk along it.
