Whenever you have a quiet evening, I highly recommend you check out this 50 minute documentary about plastering craftsmanship in Japan. I’m not sure when this was produced, but not anytime too recently. The production has that smooth, slow, gentle vibe that will whisk you away. You don’t need to understand Japanese to glean a lot of valuable information about the process and workflow of creating beautiful clay and lime walls. Much respect to the sakan. This is heavenly.
I’m a big sucker for the series Begin Japanology / Japanology Plus. It’s a long-running TV series that dives into specific aspects of Japanese culture, hosted by the mild-mannered Peter Barakan. The premise and delivery are very simple, and there’s an episode for seemingly everything Japanese.
Recently, an episode devoted to Japanese plastering was released. It’s an informative, inspiring look at the history of plastering craft, and some of the newer work being done today.
One word: storehouses. Check it out!
Now that the episode of “Who Wants to Come to Japan?” (世界ニッポン行きたい人応援団) has aired, I can talk about my experience during the filming week. The first thing I want to share about is my visit to the Sugita family, a very generous family who run a top quality trowel business. Started by Sugita-san senior, the business (Sugita Kogyo) is a small operation and is now mostly handled by the son. During my two day visit, I had the privilege of observing Sugita-san’s process for making a hand-forged jigane trowel.
Plaster, trowel, and tool geeks — read on.
I’m back home from Japan. I can think of no better word to describe the trip than ‘whirlwind’. It was very full and varied, and it’s taken me over a week to feel settled back into home life and routine. (The jet lag on the way there was almost nonexistent, but it hit me like a sack o’ potatoes on the return trip.)
It’s hard to summarize such a long trip, so I won’t really try. I’ll say this, though — I definitely want to return, and plan on it at some point. My goal right now is to document some of my trip highlights in a series of blog posts. I can’t share much about the first week (yet), so things will have to be out of chronological order. Not that it matters.
Enough jabbering, let’s get on to the good stuff. Here are some pretty pictures of clay walls and kura (storehouses) in the lovely city of Kurashiki, a small historic city I loved exploring.
The world of natural plasters runs deep. Despite the seeming simplicity of plaster, there’s a lot of depth to explore. Materials, recipes, tools, and application can vary widely from project to project, person to person, and place to place. Although there are some good resources on the subject, there haven’t been a lot of in-depth publications focused on plastering in North America specifically.
Luckily, that’s changed with the release of Essential Natural Plasters. This is easily my new favorite resource for natural plaster recipes and techniques. The authors Michael Henry and Tina Therrien (and a host of contributors) shine a bright light on the sometimes mysterious subject of clay and lime finishes.
A couple of weeks ago, we hosted our first Natural Building Essentials Workshop of the summer. What fun! The weather held out and we had great camping conditions, and April cooked up a veritable feast for our intrepid mudslingers. I think it’s fair to say everyone had a great time, myself included. Check out some photos of the course below!
A white clay plaster finish meets the earthen floor made with site soil
This winter, I had the chance to revisit a home that I worked on last spring. The homeowners have moved in and it was very sweet to see the house in a finished state. It’s a great feeling to contribute work and then see everything tied together in the end. The finished look is great — the earthen floor looks smooth and feels soft on the feet and the clay plastered walls add brightness and texture. Look ahead to see more pictures.
Did you know that you can polish clay plaster so that it has a reflective mirror finish? It looks spectacular, and Benito Steen (son of Athena and Bill Steen, straw bale experts of the southwest) has a new video describing his process for achieving the effect. Benito has done a great job describing the process in clear, simple term. The video is beautiful to watch, too.
Check it out above and learn for yourself how to make a polished clay plaster finish with very simple ingredients. Hope to see more videos like this soon!
Clay plaster base coat application in process
Clay soil is one of the most ancient, rudimentary, yet effective building materials on the planet. Besides being naturally abundant across much of the earth, clay has unique properties that make it not only suitable but very desirable as a natural building material. Clay is used for the production of fired brick, sun-baked adobes, cob, and natural plaster finishes.
In this very basic introduction to clay soil, I will highlight some of the unique water-loving features and other useful attributes of clay when it’s used as a natural building material, particularly as a plaster finish.

I was excited to find this video documentary about Japanese clay plaster as it’s currently being practiced by sakan (a.k.a., traditional plasterers). From what I gather, clay plaster is a niche craft in Japan, but the tradition has been unbroken for hundreds and hundreds of years. It’s not practiced as widely as it once was, yet the quality of the work that is done is exceptional. It’s serious business, and absolutely beautiful and inspiring too.

Hi there, I’m Ziggy. In 2008, I launched The Year of Mud while building my first natural home. This blog is a collection of personal stories and experiences building with clay, straw, and wood over the past 15+ years. A few of the things that get me fired up are natural plasters, timber framing, & Japanese architecture. Since 2012, we’ve been hosting Natural Building Workshops so you can learn essential skills to build your own natural home.
