Finding land with a traditional Japanese building for sale in the right location can be close to impossible regardless of budget. But, there are a number of these old traditional kominka available for purchase and removal across the country. If you find the right piece of land you may be able to relocate an old house of your choosing to the land.
These buildings can be bought for next-to-nothing. The real cost is in the actual relocation, although you may be surprised to find out that relocation costs may be similar to the cost of building a brand-new, average home.
