Why Ocha or Green Tea Is Great

Essentially, there are three categories of tea - green tea, oolong tea, and black tea.

Each category is defined according to each tea’s oxidation level or fermentation process, the way teas are made from the leaves and leaf buds of Camellia Sinensis.

Black tea is fully fermented.

Oolong tea is partially fermented.

Ocha or Japanese green tea is not fermented.

Now, the fact that Japanese green tea is not fermented and simply baked, heated, or steamed keeps its vital nutrients intact.

It is high in antioxidant called EGCG or epigallocatechin 3-gallate.

Ocha’s Amazing Antioxidant EGCG and Health Benefits

Epigallocatechin-3 gallate, epigallocatechin gallate, and EGCG are one and the same.

It is a kind of catechin, a potent antioxidant that fights free radicals, which are major causes of dreadful cancers, heart diseases, aging, a host of ailments, and other damages to human tissues and cells.

As an antioxidant, ocha’s EGCG is even better than Vitamin C and Vitamin E.

Vitamin C works by stopping damages to the molecules while Vitamin E scours for free radicals and fights them.

Research, however, has shown that EGCG is 100 times more effective than Vitamin C and 25 more effective than Vitamin E.

It is even two times stronger in fighting free radicals than resveratrol, another powerful antioxidant that is present in red wines.

In brief, some of the wonderful health benefits of EGCG include:

  • It may regulate the viral infections such as those in HIV.
  • It may treat certain kinds of cancer – bladder, brain, cervix, and prostate.
  • It may prevent atherosclerosis or the hardening and narrowing of arteries.
  • It can lower bad cholesterol levels.
  • It is beneficial to people with heart diseases.
  • It can slow down the signs of aging.
  • It may facilitate weight loss and keep obesity at bay.

Ocha, Diet, and Weight Loss

Ocha is not The Holy Grail for weight loss because there is no such thing.

It is not a drink that can melt fats away like a dream.

It is not a miracle drink for dieting.

Research, however, proves that ocha or Japanese green tea can facilitate fat-burning processes.

It was found that EGCG encourages heat production or thermogenesis, thereby slightly speeding up metabolism and even substantially over time.

It was also found that drinking ocha was better than drinking water or coffee for dieters.

Paired with exercise and a balanced diet, ocha can be a valuable addition to an effective weight loss plan.

Types of Ocha or Japanese Green Tea

In Japan, drinking green tea has become so much a part of the people’s culture that it has spawned several varieties, each slightly different from others in terms of taste and quality.

In a gist, here are the different kinds of ocha:


  • has the highest level of quality among ocha
  • most expensive among all ocha
  • cultivated in fields that are shielded from direct sunlight
  • has slightly sweet taste
  • prepared by steaming and drying


  • has the second highest level of quality among ocha
  • cultivated in fields that are exposed to direct sunlight
  • best harvested in April and May
  • has sweet aroma


  • cultivated between summer and autumn seasons in Japan
  • has deep flavors and sweet aftertaste
  • relatively affordable than gyokuro and sencha


  • famously used in Japanese tea ceremonies
  • created from gyokuro and then made into a powder form
  • has bitter-sweet taste


  • created from bancha and brown rice
  • has a pleasant and not-so-bitter taste


  • created from roasted tea leaves
  • comes in earth-brown color
  • low in caffeine
  • has refreshing taste

How to Brew


  • water – 4 cups; heated below boiling point or about 190 degrees Fahrenheit
  • ocha or Japanese green tea leaves – 5 tablespoons


  1. On a heat of 190 degrees Fahrenheit, place teapot.
  2. Place leaves in the teapot.

      @teaches12345 Always happy to read your comments :) If you do a little search online, you can find several small-scale Japanese companies that export ocha all around the world. Prices vary, with gyokuro and matcha being a little more expensive than others. Also, if you have a Japanese stores near your place, chances are they are carrying ocha in its many forms. They might also have ready-to-drink ocha in pep bottles.
