our before & afters usually focus on small-scale makeovers using paint, glue, staple guns and a little elbow grease, but today we’re in for a real treat. architects alastair and kayoko of bakoko recently overhauled their tokyo “mansion” apartment and were kind enough to share the gorgeous results with us today.


alastair explains: “man-shi-yon’ is a euphemism the japanese long-ago appropriated to describe the generic concrete apartment blocks forming much of japan’s sprawling metropolises. the tiny units inside are often cramped and outdated by modern standards. ‘reform’ (or refurbishment) of any type of building used to be rare in japan. the earth-quake prone country has always had a disposable disposition to its housing, preferring to tear-down and rebuild anew rather than re-use existing dwellings. now, the boom and bust throw-away culture seems to be giving way to more sustainable resourcefulness and a preference for clean, modern living spaces.”


i think the results are fantastic and ooze a kind of sleek minimalism i hope i can attain one day, for at least some tiny space in my home. alastair and kayako also included wonderful details about the project so be sure to click “read more” below to see more images and more information on the project as a whole. you can also click here to see larger images, here for more before shots, and here for process shots. thanks, alastair and kayoko!

New to Tokyo, we decided to transform a typical ‘mansion’ apartment into a contemporary Japanese home. We arrived from London in late 2008 in need of a place to live and establish our emerging practice, BAKOKO. We settled on an small apartment in an eastern suburb, only 30 minutes by train from Central Tokyo. With a distant view of majestic Mt. Fuji to the West and a gaudy neon-lit ‘love hotel’ to the East it truly embodies the modern paradoxes of Japan. Most people don’t think that buying a home around Tokyo would be affordable, but unlike London or New York we were surprised when we didn’t find ourselves priced out of the market here.
In order to control costs and gain hands-on experience, we decided to do much of the work ourselves and hired trade contractors as needed. Working along side Japanese carpenters was a great for learning their building techniques first-hand. While there were some frustrating moments when things got lost in translation, drawing details on the wall at full-scale not to mention Japanese contractors’ polite cooperativeness overcame those communication difficulties. What a difference from builders we were used to working with in the UK.


Before demolition, the apartment was typical of Tokyo’s rapid urbanisation of the 1960′s and 70′s. The small 37m² (400ft²) unit was divided into two Japanese-style rooms with tatami (reed mat) flooring separated by paper (fusuma) sliding screens and a western kitchen. It was quaint and cozy, but that type of interior was simply made for a different generation. We gutted the unit and transformed it into one room, but with space in short-supply we found that retaining some traditional Japanese features made sense. For instance, new tatami mat area serves as flexible space for entertaining, contemplation, and occasional dining during the day. As is typical in Japan, a futon and blankets are unfolded onto the floor mats from the adjacent closet at bedtime.
Sliding doors run along nearly the entire length of the opposite wall, concealing a walk-in closet, full-height mirror, book shelves and a hot (pink) desk. We do a lot of work from home. The sliding wall allows us to quickly shut away our personal clutter when a client comes over. However, its equally vital to be able to shut your work away and forget about it at the end of a hard day.


A green line of foliage hangs above the dining kitchen counter, indirectly lit by a thin recessed strip of light opposite. Since standard fluorescent light strips are relatively inexpensive, we seized the opportunity to be creative with built-in architectural lighting features that create subtle effects and atmosphere throughout the interior.
The bathroom was divided into a new wet room with Hinoki timber floor (or sunoko) accessed from a small changing room with compact sink and mirrored vanity unit. Typical of modern Japanese bathrooms, the small, but very deep bathtub has no faucet. Instead, it is filled from digital consoles in the kitchen and bathroom. Bathing is a daily ritual throughout Japan. Since the Japanese assiduously cleanse themselves with a vigorous sit-down shower before entering the bath, it is forgone assumption that the bath water is kept clean. Rather than draining the bath water after each person gets out, a family may share and recycle the same bath water keeping it warm under the insulated bath cover for several days. The computerised system allows users to set the bath water temperature and remotely reheat it either on-demand or by setting a timer. A chirpy female voice chimes in when the bath is ready. The system also controls the hot water for the rest of the household.
The old squat toilet was replaced by another marvel of Japanese sanitary innovation. Ensconced in mat black walls and illuminated within a halo cast from the concealed light above is the Washlet. From a control panel on the side of the western style toilet the user can operate an built-in bidet function. Although this less-expensive model lacks advanced features such as an auto flush, self-opening and closing toilet seat, music player, or variable jets, the faucet on top of the tank is more practical, allowing users to conserve water by washing their hands in the re-filling water destined for the next flush.

this is impressive. i’ve always loved the minimalistic/ultra modern look, but i’m not sure i could actually live in a space so bare. some days it would definitely be a welcome environment after being bombarded with images and media all day.
This is pure beauty!!
I love those green floormats! Can you provide any details on them?
Takes my breath away!
*bookmarks…
the colors and minimalism certainly give it a clean look which i love; i would need a room/studio where i could be free to be a “bit” messy.
That is amazing!
This is a super reno—very inspiring.
Such an efficient way to live. I will keep it in mind (bookmarked for sure) for when we build our infill dwelling/garage at our back lane.
Superbus !!!! It was hard to imagine the result seeing the photos ‘before’ ! Congratulations !
Wow…it was so yucky before :( It’s a massive improvement – I think the bathroom is my favorite part.
Love the white with sparks of color. So clean, calm and elegant.
I love the brightness and simplicity!
they did an amazing job! And they live on even less square meters than i do! I do wonder where the bookcases are though…
amazing transformation!
I used to live in Tokyo, in an apartment just like this (of course the “before” version)
You guys did a fantastic work and I can’t believe that an old Japanese apartment could be reformed so beautifully.
HAVE TO HAVE that teak floor in the shower area. Unbelievable! Going in the “inspiration” file :)
I love this! So great.
Love, love, love it ! For such a small space, this is THE way to go !!
This doesn’t even look like the same house!! AAAAAA-MAZING!
*sigh*
i wish my apartment in japan had been 1/4 this nice! well done!
omg – I really really want to live in this apartment! I love it!
Oh I just love those big, bold colors. My kind of space.
Stunning!
Eye candy. I love the detail of the faucet mounted to the side of the bathroom sink. One day when I finally get around to upgrading a bathroom I might try this. Not because of space concerns, just for the fun of it!
I’ve lived in Japan for 20 years and I can tell you that 95% of Japanese domiciles resemble the “before” and less than 1% resemble the “after”.
The “after” looks great, but it also hasn’t been lived in yet, so it’s a bit more of the way a showroom space looks rather than a real home.
Lovely! Can anyone ID the bar stools? I think they would be perfect for my space.
TIA!
Wow, not only the apartment looks amazing but also the detailing is very impressive and well thought-out.
this was fascinating to read about!
As a Tokyo mansion dweller, this is very inspiring! Thanks for posting these great pictures.
I love the kitchen. It looks great and airy.
incredible! that’ really a beautiful work!
So gorgeous. I honestly find smaller spaces more inspiring and easier to work with!! I love the wooden floors in the bathing room. So cozy.
Very interesting! Cool clean modern sollutions..I am especially intrigued by those green mats?I love their look,what exactly are they?
Agree with Orchid64, when the magazines, newspapers are strewn in the living area, when the papers stack up on the desk, when the sauces, pots, pans and dishes are all over the kitchen, when the bedroom is hung with worn clothes, somehow it paints a different scene, sorry to say this. BUT it does look lovely now as it should.
The renovation is fantastic! I use to live in an old mansion like that in Tokyo with very little space. The modernisation is inspiring! Love the new bathroom and kitchen area – good use of space.
LOVE… or at least a giant crush!
love, love, love this post! I have never commented here before, but this did it for me. What is it about Japan? I find it so aesthetically pleasing. thank you.
Constructive criticism, since all the other comments here are positive: I vastly prefer the “before”, with its warm colours and natural materials. The “after” looks like a revamped sandwich bar, a relaunched branch of McDonalds, or an Ikea catalogue. Original design has to try harder than this!
I love the look, beautiful place…
but probably the main problem I have with it, the bedroom…
I know I know that everyone sleeps on the floor…but I could never do it. The idea of sleeping so close to the messy floor with a possibility of small animals and bugs crawling all over me…kind of sinks the deal.
Just get me a bed at least 2 feet off the ground and im there!
great use of space and splashes of color
Fantastic for a first project. These folks really do have amazing design ideas, and bring them beautifully to reality. Can’t wait to see what you will do next.
sugoi! daisuki!
Wowee! Fantastic clean lines and white as white. Fabulous for accent colours if you wished to introduce patterned or other coloured accessories.
That’s the beaut thing about white – can add a splash of colour at any stage.
The simple japanese or western influence is superb and gives the fensui feel, I think!
Simple and gorgeous.
I like very much.
THANKYOU!

I felt a little sad when I read that they removed the original paper slide doors… but they wouldn’t fit the new design I guess. It looks great now, but not so personal (like some people commented, showroom-y). Some art on the walls would help to make it feel more personal I think. My favourite part is the floating plant box in the kitchen.
I’ve been looking for modern furniture designs and i came across your website in search for one…you have great posts here…i love your website…I am definitely going to bookmark this.
Your apartment is so beautiful, clean and minimalistic oh how I wish I could live like this but unfortunately I need my clutter!
What a great reno! I love the touches of color in various nooks. It gives the space a lot of character.
