Dr. Ryohei Mimito who is the director of Mimoto hospital in Japan has become well known for treating burns by wearing Fundoshi. He also found that pressurising the body by a rubber band used in underwear could be the very cause of various diseases.


Wearing Fundoshi helps better blood circulation and could improve constipation, cold feet and hands, shoulder pain and quality of sleep.

Some people are loving wearing this super underwear.


Niji brand’s dyed products offer soft texture of bamboo clothes and gentle colours derived from natural plants, upgrading your daily life with relaxation and wellbeing.

We recommend these products as a gift for your loved ones.

We also produce handmade natural broom for sale.


Under Mrs. Narawat’s direction, we go through a whole process of making, from picking up the plants, preparation and sewing.


When the plants for the broom bloom the flowers in January, our children go to the mountain to pick them up. They bring their lunch as it is a day long job, walking for a long distance. When the plants are dried out under the sun, we bat them on the floor to take off all the powdered pollens. Then follows endless work of cutting off the useful parts into the same length in the shade. When we gather plenty of them, we finally sew them together to make a broom.


It is a difficult work for little ones as it requires detailed and effortful attention. Children over 12 years old learn from Mrs. Nawarat step by step so that they can master the skill. OK, one of our boys was so good that he learnt it very quickly.


This time-consuming handmade broom cleans wherever it needs tidy floors with soft touch. Please try it!



– Large Broom 100B

– Small Broom 200B (Small one can be used for a table broom or for kids use)


Every December, we hold a workshop when our children teach how to make a small broom in Bangkok.


Please join our workshop if you are in Bangkok. (Workshop fee 100B/per work)

Yukata is a Japanese evening gown. Rainbow school offers rental Yukata, workshop on how to wear it and photo shooting at this extraordinary Thai rural location. Our children will guid you through the experience. The profit is contributed to children’s daily and education fees.


Because Rainbow school is managed by a Japanese couple, we would like to offer some Japanese cultural experience to our guests and neighbours, which eventually supports children financially. 


The price range starts from 200B. 

Please make a reservation when you visit the school.
