Natural Mineral Water of Japan

I love Japan's mineral water.   I'm a sentient being, so water is more then just a colorless, tasteless, and odorless beverage, it's  a precious resource that comes in many flavors and textures.   Even mineral content can vary from one minor degree to the next, which all have an effect on the taste.   Water is the quintessence of tea and nihonshu in Japan.  It is also the quiddity of every onsen ever soaked since time immemorial.   In Japan water is king!


One of the things I like most about Japan is that almost every prefecture  has its own mineral water source.  This is good for so many reasons, one of them being for making good sake, especially nihonshu.  Mineral water has also been used for growing delicious fruits and vegetables.    I will attempt to highlight some of my favorites and that of many other water aficionados in Japan.


First, let's start with some household name brands.  The first is called Rokou no Oishii water and it's from Osaka.   Almost every supermarket chain in Japan carries this brand.  Natrium is 2.95mg/Calcium 0.65mg/Magnesium 0.37mg/potassium is 0.08mg.  The pH is 7.2.  If you like something soft and with very little mineral content then I recommend trying this one.   A lot of elderly people buy this brand for some reason.



Next up, the picture below, is called Suntory Natural Mineral Water from the Minami Alps.   Now I like this water very much because it has a little more acid and mineral content than the first one.    The pH is 6.7, we get 0.97 calcium and 0.28 potassium.   It gets its taste from the lower pH, which for me has a perfect balance that make a mineral water taste great; refreshing taste, good medium hard water consistency.



Another interesting tid bit is that it's bottled on site, or at the water source itself!   Most times water is transferred to a processing plant  first and then bottled, which isn't necessarily a demerit, but a good precautionary measure in case there's something detected in the water itself, and also to remove excessive calcium and magnesium, which are the two main minerals that make water hard.


Leaving Kanagawa Prefecture there are two very nice mineral water choices.  Ones from Shinshu/Nagano Prefecture and the other is from Kumamoto Prefecture on the Island of Kyushu.


Let's start with Nagano Prefecture first.   It's called Kiso no Oishi Mizu / 木曽のおいしい水 and it's a soft water type that's very easy to drink.   It too is bottled at the source. 


pH 6.8, Potassium 0.94mg, Calcium3.0mg, magnesium 0.54mg.    There're a couple of supermarkets down in my area that sell this one.  Not particularly my favorite, but the taste could easily appeal to the soft water drinker.  Kiso is a very famous part of Nagano, by the way.  Been there and loved this place, especially if you are into Hinoki and onsen. 


The last really good one  is called Shirakawa Suigen, Minami Aso Hakusui Village from Kumamoto Prefecture located on the Kyushu Island of Japan.  According to the legend, a long time ago, the dragon god of water lived in the gushing waters of the fountainhead. 


Natrium is 1.0mg, calcium 2.3mg, magnesium 0.6mg, potassium, ph 7.1. Mineral content in water does make a difference in taste.    Calcium content is high in this one, so the tongue may think it's a hard water when in actuality it really isn't that hard.   Often times when you hear words like "pH" then you need to thing more along the lines of how it has an effect on human skin, and not so much on the taste.  



The higher the pH the more emollient properties are in the water.  This means that it makes your skin feel smoother and with a mild astringent affect.  How it relates to you internally may have something to do with  aiding in digestion.....  Natrium is just another word for sodium. 


All-in-all, Japan's got some pretty good mineral  water.   I plan to continue this water series this week, but only next time it'll be with mineral water used to make Japanese sake!

Shin-Okubo: Little Korea

So I finally got around to going up there to Shin-Okubo,  the land of Seoul via the Yamanote Line.  Been putting this trip off for years for personal reasons;  I am not a fan of Hanlleyu.      I knew why I came up this way, and for none other reason than the food, and maybe to bask in the nausea of Korean romanticist who steal Japanese Jukujo's souls.    But honestly, I like spicy food and stews and pickled vegetables that challenge my taste buds.    I also love the little funky cafes that line the main thoroughfares and alley ways, each with their own little eclectic menus and interior decor.     This place is Korea.  

Shin-Okuba represents more than just a place to relish in Korean culinary delights and K-pop culture, but a place where Koreans can express themselves through their culture.    You can feel the local vibe in the air as you're walking down narrow walkways and footpaths.    I have personally been to mainland Korea six times, so a lot of the nostalgia was there …

August: The Return of Souls

August is peak summer season in Japan.  We can look forward to some of the most spectacular fireworks displays and festivals in the world, especially  in places like Tohoku and Kanto regions.  August is also  the most contentious month of the year in Japan; with the end of the war and war-related guilt.    Then there's the great exodus back home for millions of Japanese.   Obon season is what it's called in Japan, and it's  where families return to their hometowns to remember their ancestors and to spend time with loved ones.  Gravestones are visited, cleaned, and washed; rice or alcohol is often placed on  miniature altars next to a  headstone.  This is a way for Japanese to reconnect with their roots; a way for them to stay grounded and founded in the ways of tradition and cultural protocol.   

For the foreign tourist, some places will be overcrowded and expensive to reach; for Japanese, this is normal and can't be helped.   Wherever you go there will be lines and h…

Japan Board of Education: Amazing Grace...?

Japan Board of Education Textbook.
Amazing Grace
Shuken Shuppan  Polestar textbook English Communication

Preface:  Japanese / Japan is  one of the leading donors in humanitarian aid around the world.   They have donated billions of yen to charities, developing countries, and startup business to just about every country on the globe.  Some Japanese have even taken matters to the extreme  to the point of poking their noses into hotspot areas like Palestine and Isreal, things the Japanese may want to avoid.  Had Japan shared its borders with an ethnic minority with its own government, the relative peace and calm of this country would be questionable.   No other country can be like nor emulate Japan.   So, where does this spirit of charity and altruism come from exactly?   Why do the Japanese feel they need to save the whole world, while caring very little for its own people?   It's the Board of Education...?  The essay below is one such example of what Japanese kids learn in school,…
