Area Conversion in Japan
Author: Wayne Hemrick
Area conversion in Japan is a slightly different matter, however. For most purposes, the Japanese use the metric conversion of units; areahowever is still measured by a traditional method dating back some 1300 years.
The Shakkanh? System and the Tsubo
The shaku is a unit of length; the kan is one of mass. These words combine to form the term shakkanh?, which was adopted during the Nara Period in Japanese history, when the loose confederations of warring rival principalities were starting to coalesce into a unified nation. This system of measurement and area conversion was used until well into the 20th century.
The Japanese government adopted the metric system in 1924 and made it official for legal purposes in 1966; however, when it comes to real estate, the old shakkanh? system has prevailed.
The basic unit is the jo or go, which is considered to be the size of a tatami mat. When real estate transactions are discussed, a piece of property is often said to be valued by the tsubo, which is the same size as two “standard” tatami mats (the traditional type of woven straw flooring). Similarly, rooms in a building are measured in terms of tatami mats.
“Standard Area Conversion?”
The traditional size of a tatami mat is equivalent to 90 by 180 centimeters, or just a little under one by two yards. When discussing conversion area however, the term “standard” is a bit misleading, as the exact area of tatami mats vary slightly from one part of the country to another. A “standard size” room in Japan is supposed to be equivalent to 6 jo; an area conversion table will tell you that this is about 18 square feet. However, older buildings often have larger 6-jo rooms than newer ones. Different area conversion tables will correspondingly give you slightly different area conversion results.
Because of the variability in the size of tatami mats, there really isn’t an area conversion calculator that will be of any help in giving you an exact area conversion figure. There are calculators that provide metric conversion functions priced around , but when it comes to area conversion in Japan, all it can do is give you a rough figure,

Voting is 139th of 172nations who vote, Residents of 27 Countries live longer, Foreign debt 2.1 trillion,Unemployment rate is higher than 38 other nations, U.S. spends almost as much on the Military as all other nations combined, Murders 15th highest murder rate…..
Does Japan really have self-sufficient solar energy homes?
I have heard from a friend that in Japan, they have some houses that utilize solar energy to power the house and charge their electric car, and this is the only energy it ever needs. Is this true, and where can I learn more about it?
Why do we use solar energy on Mars but can’t get leadership to support it on Earth?
The polar lander just landed and one of the first items on it’s agenda was to deploy it’s solar panels. The lander probably consumes more energy than your pc. Now there are 3 spacecraft on the ground and 3 orbiting mars that use solar. The amount of solar energy received that far away is less than received at earth. Even the two rovers that have been on the surface for about 4 years now continue to work even though they have endured martian dust. Isn’t the real reason solar isn’t used more on earth because it would take revenues away from big oil and power corporations? Considering a significant number of people live in the sunbelt, why don’t we have solar on the roofs of every home? Couldn’t we use both photovoltaecs and solar water heating? Will Americans be leaders in this technology or do we have wait till Japan or China starts to manufactures them? I realize solar has limitations but it will be there forever.
Why so little about the nuclear leak from a sub near Japan and another in facility near Vienna. Safe energy?
It’s all about energy this week but nothing about very serious concerns over safety in two nuclear mishaps. And too few links between the nasty fuel spill on the Mississippi River last week and McCain canceling his visit to an offshore rig near New Orleans. And no mention of the remarkable research results on storing solar energy announced by MIT scientists. It’s just drill, drill, drill.
Will China takeover the US as Obama refuses to use oil & drives up the price of energy here via Wind/Solar?
Does Obama figure Saudi Arabia, Iran, and Venezuela will just quit producing as much oil just because he has the US use more expensive solar and wind energy?
Won’t Saudi Arabia just sell more of it to China and Japan as those countries because the industrial powerhouses with higher standards of living?
Nothing new. I have several friends in Mexico that have homes that are not connected to the electric system and use solar power with battery bank for storage.
This is well known old technology. Solar systems are great and works well. It is just very expensive relative to the electric power grid in most areas.
Japan should be very advanced in this area because they have had very high power cot for many years. It is primarily the cost effectiveness of solar that is holding it back. It is also not reliable in many areas due to cloudy weather and shorter days.
Huh? Everyone in the world is buying less oil, including China and Japan. OPEC is reducing production to help increase the price of oil right now.
You sound like another of these folks that think there is an endless supply and we should not do anything to develop alternative sources.
wasn’t there actually a guy whose leg was contaminated by that nuclear stuff? Why hasn’t these incidents made front page? Alarming and Disappointing.
First, I support solar energy resources. And it isn’t just photovoltaic, but wind and hydro, also. The problem is the return of the investment within the time frame of owning the property. See pv panels work best as decentralized power source. So they have to be used on a building, not a massive array. They generate a low voltage that isn’t very efficient for transmission over long lines. But because people don’t hold on to their individual properties for them recoup to the investment, they choice makes little sense. Until traditional electricity becomes so expense, that the investment will pay for itself within the time frame of ownership or they become an added value on resell, let’s admit it most people consider them ugly, people aren’t going to make the change. Also PV panels deliver a low voltage, so many of the household appliances would need to be changed or other modifications to the electrical systems to accommodate the low voltage.
The other thing is we could use is passive and active solar heating. Solar water heating if used to heat the home is an example of active solar heating, while trombe walls, thermal mass are methods of passive solar heating. The problem in this area is the cookie cutter method of construction in residential construction. Most homes change little from region to region. A $400K will have similar plans from region to region, as a $150K will have similar plans. Construction methods will change determined by the most efficient methods for the region. For example, in Florida a $200K home will likely be build on slab, CMU walls, stucco exterior, while a homes in the Midwest will likely be build on a crawlspace, stick framed, brick and siding exterior. These are regional response to the construction, but the plans will be similar. But a solar home needs to be specifically designed for the region, even the site conditions. Point is with most solar homes you need a specific design. That is another increase in the investment. And trust me, builders don’t like to shell extra’s for upfront design.
Image this a builder is putting in a subdivision, is he going to have plans for the south side of the streets, plans for the north side of the streets, mixed used communities, etc? Or is he going to maximize the land use, have a few plans for the size of lots, and maximize profits?
As for remodel, similar issues. The house was not likely designed to maximize solar power to begin with, and the owners aren’t likely to make the initial investment, if they can’t recoup the cost in energy savings or resell. These are why many people remodel, for short term enjoyment, and resell.
Don’t get me wrong, there is a lot of potential within the coming years for these technologies, but it won’t make a major change, until there is watershed moment, in the form of the technology drastically becoming more affordable, traditional energy becoming so expensive it makes financial sense, or a collective mindset to make the change.
Of course, the main reason they landing craft use solar panels, there are not robotic fueling stations on Mars or the moon. HaHa.
Yes we are
