Watermelon Juice

I was not a big fan of watermelon growing up.  When my brother-in-law introduced watermelon juice to me years ago, I was reluctant to try but ended up being surprised by how delicious it was.

Growing up, watermelon was the most common fruit during the summer time in Japan.  We usually spent the summer in my grandparents’ home in Osaka.  They have a big backyard and I remember having watermelon seeds spitting contents with my brother to see who can spit farther.

I also remember eating watermelon with my late grandpa on the porch after helping him tend the garden.  When my family went camping, we would put the watermelon in the river to cool and played a traditional Japanese game called suikawari (スイカ割り).

Suikawari is a game where everyone takes turn to smash watermelon with a stick while blindfolded.  The rule is similar to piñata except you play with a watermelon.  Each person is blindfolded, spun around three times, and handed a wooden stick to strike with.  The first to crack the watermelon open wins, and everyone enjoys the chunks of watermelon afterwards.

Hope you try playing Suikawari and making watermelon juice this summer!

    I think I’ve found my answer for how to survive the Texas summers! This watermelon juice looks so refreshing and perfect for beating the heat. I love your addition of mint and lime, Nami!

  • Monica June 26, 2013, 7:44 am

    I would so gladly welcome a tall glass of this right now. It’s been so hot this week and I’m going through fruit like water. : )

  • Mr. & Mrs. P June 26, 2013, 7:45 am

    Had no clue that such a game existed… Sounds like fun!! What a great and easy juice!

  • Laura @ Family Spice June 26, 2013, 8:01 am

    Oh we don’t beat our watermelons but we love eating them and juicing them. Lately my husband has been literally juicing them, cramming watermelon pieces into our wheat grass juices, to separate the fiber from the juice. Kids love it! Stay cool!

  • Betty Ann @Mango_Queen June 26, 2013, 8:06 am

    I want to drink this all up right now. This post is so refreshing. Love your description of the ‘watermelon-smashing’ game. I never knew about it, but now glad to learn. Thanks for sharing this thirst-quenching recipe, Nami!

  • Averie @ Averie Cooks June 26, 2013, 8:08 am

    This would go down SO fast and easy! I love watermelon, too! Mmmm, so good :)

  • Alayna @ Thyme Bombe June 26, 2013, 8:09 am

    I’m normally not much of a melon fan, but I just can’t seem to get enough of it this summer. This looks so refreshing!

  • ASmita June 26, 2013, 8:10 am

    So refreshing! Perfect for the summer!

  • A_Boleyn June 26, 2013, 8:20 am

    Looks delicious and very refreshing.

  • Shema George June 26, 2013, 8:20 am

    I love watermelon juice…so refreshing in summer.. Nice presentation Nami

  • Sandra June 26, 2013, 8:34 am

    Love, love this recipe!! Can’t to try it :)

    • Nami June 26, 2013, 3:47 pm

      Thanks Sandra!

  • Kate from Scratch June 26, 2013, 9:29 am

    This looks so bright and light and delicious. I will definitely try this – sounds perfect!

  • john@kitchenriffs June 26, 2013, 9:48 am

    Suikawari sounds like a lot of fun. Messy, but fun! I love watermelon – it’s our usual breakfast at this time of the year, and we often go through a couple of seedless ones each week. I’ve not made watermelon juice, but I must – it sounds so delsh. Very refreshing. Thanks for this!

  • Jenny June 26, 2013, 10:19 am

    Ooh that looks so refreshing, Nami, and the COLOUR! just beauatiful. Lovely recipe… I suppose you could add a dash of vodka, too!

  • Ash- foodfashionparty June 26, 2013, 10:21 am

    Interesting game, spitting the seeds sounds like fun…
    The idea of drinking a tall glass of watermelon juice with lime, make me feel cool, chill and calm. Thanks Nami, I have a huge watermelon sitting on my countertop staring at me for couple of days. We are lazy to eat it slice by slice sometimes, this is a good alternative, and you get all the nutrients in one go.

  • Evelyne@cheapethniceatz June 26, 2013, 11:01 am

    Watermelon is so refreshing, love the idea of drinking it. Yes I must play Suikawari once in my life lol. Who was that guy in the 80s who always smashed watermelons on tv?

  • Muna Kenny June 26, 2013, 11:14 am

    How refreshing Nami! The summer here is killing and juices are consumed like crazy. I can get real sweet watermelon this season, and would love to try your recipe :)

  • wok with ray June 26, 2013, 11:44 am

    Looks very refreshing and what a beautiful photography of the juice. It feels like I am looking at a cover of food magazine. Really nice color coordination.

  • Cheryl June 26, 2013, 12:11 pm

    My son LOVES this stuff Thank you!!!!

    • Nami June 26, 2013, 3:26 pm

      Thanks Cheryl! :)

  • Reem | Simply Reem June 26, 2013, 1:02 pm

    I love watermelon in every possible form… LOL
    This juice is all what we need to beat the summer heat.
    Enjoy your time with your mom…. Have Fun Nami!

  • Kelly June 26, 2013, 1:20 pm

    Yum, this looks so refreshing! Love the vibrant color of this watermelon juice. The addition of lime and syrup make this the perfect drink to cool down with. Stunning photos too Nami :)

  • Hester @ Alchemy in the Kitchen June 26, 2013, 1:27 pm

    Nami, such pretty styling and the perfect thirst quencher for the summer. Suikawari sounds like good exercise too ;)

  • Marta @ What Should I eat for breakfast today June 26, 2013, 1:34 pm

    I’m glad to hear about Suikawari, I want to try it now, hahaha. It has to be so much fun. Your recipe sounds very represing.

  • Kitchen Belleicious June 26, 2013, 1:40 pm

    this would go great with my watermelon rice krispie pie I posted today! what a delicious and refreshing treat!

  • CCU June 26, 2013, 1:54 pm

    This is so refreshingly delicious, I would love to drink it!

  • Eileen June 26, 2013, 1:57 pm

    Watermelon juice is possibly the most refreshing beverage on the planet! this sounds like an amazing drink for a hot summer weekend. Love it!

  • Mel June 26, 2013, 2:14 pm

    A refreshing drink. Loves watermelon at any time.

  • nusrat2010 June 26, 2013, 2:26 pm

    Watermelon juice is my bosom buddy during summer time :)
    Heart-winning colorful, cool pictures :)

  • Lauren June 26, 2013, 2:58 pm

    I love watermelon juice so much! I find the extra sugar/syrup not necessary as the fruits is already very sweet. I’ve never thought about adding lime to the watermelon juice, although growing up my grandma would add it in her papaya juice. So great tidbit!

  • Hotly Spiced June 26, 2013, 4:54 pm

    That watermelon game sounds a lot more healthy than what we see coming out of a pinata! I love watermelon juice and find it very refreshing during hot weather. I love your jar/glass, Nami xx

  • Anne ~ Uni Homemaker June 26, 2013, 5:04 pm

    I love watermelon juice! It’s so refreshing. Love your addition of lime in here. Will have to try that next time I blend some up. Thanks for sharing Nami. :)

  • Jayne June 26, 2013, 6:44 pm

    haha.. that game sounds like so much fun! Even better if the watermelon is super cold. We eat tons of watermelon here, since it’s rather warm and humid most days. Really cools us down and keeps us hydrated well. One of our very favourite fruits.

  • Sylvie @ Gourmande in the Kitchen June 26, 2013, 8:23 pm

    I’ve never heard of Suikawari before but it sounds like a fun idea for a summer picnic!

  • Mich Piece of Cake June 26, 2013, 8:57 pm

    I love fruit smoothies and I think this is perfect! We get lots of watermelon all round and will buy one to make some with a dash of lime!

  • Peachy @ The Peach Kitchen June 26, 2013, 9:03 pm

    Suikawari is an interesting game. Will try it out, there are lots of watermelon here!

  • Laura (Tutti Dolci) June 26, 2013, 10:02 pm

    This looks so refreshing, Nami! I love the color!

  • MnYfoodtalk June 26, 2013, 11:53 pm

    Hi Nami-san, may I know where is your grandpa’s yakiniku restaurant in Osaka? Thanks.

    • Nami June 30, 2013, 4:11 am

      It’s called New Matsusaka (ニュー松坂) in Umeda, Osaka. :)

      • MnYfoodtalk June 30, 2013, 7:19 am

        Thanks. If I have chance, will visit your grandpa’s yakiniku shop. Are you in Osaka now?

  • Giulietta | Alterkitchen June 27, 2013, 1:27 am

    I’m not a fan of watermelon, too. But if you were skeptical like me and you loved it, maybe I should give it a try :)

  • Ramona June 27, 2013, 3:11 am

    We have yet to buy a watermelon this season. Prices are finally getting good around here so I think this week will be our first taste of watermelon for the summer. I love the watermelon game you play… it sounds like something both kids and adults would enjoy. :)

    The drink looks amazing. :)

  • mjskit June 27, 2013, 8:55 am

    Your story is very interesting to me, because I could have written it! :) I have the exact same memories growing up in Louisiana. Granddaddy was a farmer and had a huge watermelon patch, spitting seeds (which you can’t find in watermelons today), smashing watermelons and eating the chucks… Amazing! However, two differences – I’ve always loved watermelon and my memories are AT LEAST 2 decades earlier than yours. :) Great story Nami! Love the watermelon juice! The watermelons I’ve been getting this year have been so sweet that sugar hasn’t really been needed, but I do like your idea of using a simple syrup. Will definitely have to remember that as we get later in the season and the quality of the melons probably go down. Thoroughly enjoyed your post!

    • Nami June 29, 2013, 5:08 pm

      Hi MJ! Your comment made me very excited and happy, MJ! Two different countries with almost same summer watermelon memory! Thank you for your kind comment. xoxo

  • Jaclyn June 27, 2013, 9:05 am

    Very pretty photos Nami! I need to make this at least once this summer, I know my whole family would love it!

  • Sandra | Sandra's Easy Cooking June 27, 2013, 9:17 am

    This is absolutely GORGEOUS! So vibrant and refreshing… We love watermelons and nothing gets my summer cravings than freshly opened aroma of watermelon. Perfection!

  • Nik@ABrownTable June 27, 2013, 9:17 am

    I absolutely love the first two photographs! This is such a great refreshing summer drink especially with seasonal watermelon fruit!

  • Rosa June 27, 2013, 11:06 am

    Delightful! That is the only way you’ll see me enjoying watermelon (I’m not a big fan of that fruit – too sweet and bland, in my opinion). ;-)



  • Kate@Diethood June 27, 2013, 11:10 am

    I do not like watermelon, but that looks SO refreshing! And pretty, too!!

  • Purabi Naha | Cosmopolitan Currymania June 27, 2013, 12:24 pm

    There is an old-fashioned game in India, similar to Sukimari. The only difference is that they have an empty clay utensil for that breaking part. I am sure, this watermelon juice will cool everyone in this hot hot weather. Sometimes, simple is the best!

  • Sissi June 27, 2013, 2:03 pm

    Nami, your watermelon juice looks just heavenly chilling… I rarely do other things than eating the watermelon as it is, apart from cocktails ;-) This drink looks perfect as it is, but I’m sure a bit of tequila of gin would go very well with watermelon too!

  • GourmetGetaways June 27, 2013, 4:43 pm

    Oh I love watermelon juice in summer, and cocktails made with watermelon juice and diet lemonade YUM! I can’t wait for summer :)

  • Linda | The Urban Mrs June 27, 2013, 5:33 pm

    LOL – the seeds spitting contest sound like fun but I don’t think I will ever win that. Watermelon juice sounds very refreshing especially since Summer is here.

  • Orchidea June 28, 2013, 4:58 am

    Hi, this is a nice drink and I will try it… I love watermelon and I look forward to summer every year to eat a lot of it! I never tried this juice by I will.
    Have a nice vacatin with your family in Japan! We will be in Italy for vacation this summer, so looking firward to it.

  • sippitysup June 28, 2013, 7:56 am

    A watermelon for a pinata! Now that game suddenly makes sense to me. GREG

  • yummychunklet June 28, 2013, 10:06 am

    That looks refreshing! Perfect for summer.

  • Hannah June 28, 2013, 6:41 pm

    Oh Nami, summer is sizzling here and I couldn’t be happier, although a large glass of this refreshing watermelon juice would certainly make the warm evening even better. Happy summer to you!

  • Jenn and Seth June 29, 2013, 8:12 am

    I love watermelon but I never had watermelon juice – such a great idea and looks so refreshing!

  • Rhonda June 29, 2013, 10:01 am

    I don’t remember having a lot of fruit in our house growing up but we always seemed to have watermelon when we grilled. This looks delicious and perfect for our hot weather.

  • Chung-Ah | Damn Delicious June 29, 2013, 5:28 pm

    How refreshing! And I just bought a huge watermelon today, too!

  • foodfashionandflow June 29, 2013, 7:42 pm

    I love watermelon during the warm summer months. I remember eating watermelon with my grandma and swinging on the porch swing. She always sprinkled a little salt on her watermelon. Your recipe looks similar to a recipe I posted recently. Watermelon makes such a great agua Fresca.

  • Jen L | Tartine and Apron Strings June 29, 2013, 9:31 pm

    Looks delicious! I can drink this the whole summer. I grew up enjoying watermelon because it was so abundant in the Philippines. My grandma used to make it to juice for me. Good memories…!

  • Amy Tong June 29, 2013, 9:44 pm

    suikawari sounds like fun. At least, it’s “healthier” than piñata! hahaha….cos the kids get to eat some fruit, and not candies, afterwards. :P My family is huge fans of watermelon anything; Juice, chunks, balls, frozen, salad, etc. Good that you like watermelon juice now. It’s so refreshing. I love your childhood memories associate with watermelon. hehehe….although the seed spitting contest, sounds like fun, I hate watermelon with seeds. :P

  • Raymund June 30, 2013, 12:45 am

    This really makes me miss summer even more, love this but I will have to wait until watermelon is in season.

  • Adrian (What the Heck is Filipino Food) June 30, 2013, 3:14 am

    You played some waaaay cool watermelon games when you were a kid!

    Aside from mangoes, watermelon IS the ultimate summer fruit with or without alcohol hehe

  • Maureen | Orgasmic Chef June 30, 2013, 3:50 am

    I love watermelon juice but never drank it as a child. We always ate it and spit out the seeds to see whose seed went the farthest. Maybe that’s too much information. :)

  • Laura|My Little Gourmet June 30, 2013, 4:48 am

    Hi Nami. I just made this juice and it was really good and incredibly refreshing. My 2-year-old loved it too! Thanks for the great idea!

    • Nami July 6, 2013, 12:31 am

      Hi Laura! Yay, so happy to hear your son liked it! Thank you so much for letting me know, Laura! :)

  • Von June 30, 2013, 7:13 am

    :O I thought watermelon was something that everyone likes! haha…. Suikawari sounds like such a fun game!! I remember seeing it in some anime and thinking that it would be pretty dangerous since you’d need to whack a lot harder than with a pinata ;) Mmm….your watermelon juice looks delicious too! :D

  • cquek June 30, 2013, 7:45 am

    The title sums it up. They can´t be anything but amazing

  • Sue| My Korean Kitchen June 30, 2013, 2:45 pm

    I’m going to try this when summer comes back in December! I can feel that it will dissolve the heat down to my throat. :)

  • Daniela June 30, 2013, 4:06 pm

    I’m with you Nami , I do not enjoy so much eating watermelon, but I love watermelon juice.
    Combined with lime juice there is nothing more delicious and refreshing in summer!

  • Stephanie @ Eat. Drink. Love. June 30, 2013, 4:33 pm

    Nami, this is one gorgeous drink! I love that bright vibrant color!

  • Baby Sumo June 30, 2013, 9:50 pm

    Nami, great job for making a glass of simple refreshing watermelon juice look so fantabulous!

  • Charles July 1, 2013, 5:32 am

    Hi Nami, I always like to eat all the seeds and store them in my mouth and then “machine-gun” them out at my target… sister, wife, cat… nothing is safe from my game!

    We bought a watermelon this weekend but surprisingly, ended up eating almost all of it already. I was considering making a juice when I bought it, so it’s very fortuitous timing that you posted this. They’re very cheap at the moment so I’ll probably buy more and make juice next time.

    • Nami July 1, 2013, 5:51 am

      Hahahahaha! Machine-gun… that’s a good trick! I can see myself competing with my younger brother. :D

      Watermelon is not cheap in Japan, so I don’t see myself making it into juice… ;)

  • Kim - Liv Life July 1, 2013, 10:22 pm

    Watermelon and lime!! One of my newest favorite flavor combos… I had no idea they went so well together. Love this!!

  • Des @ Life's Ambrosia July 1, 2013, 10:36 pm

    Why have I never thought of this before? This is a fantastic idea! And the perfect way to beat the heat in the summer.

  • Katerina July 2, 2013, 2:51 am

    The perfect beverage for summer! I love watermelon!

  • ashley - baker by nature July 2, 2013, 4:08 pm

    I love watermelon juice! It’s sooooo refreshing, and makes a nice mixer when it comes to cocktails.

  • Valerie @ From Valerie's Kitchen July 3, 2013, 8:09 am

    This is such a refreshing, summery, treat! It has been SO hot around here for the past week. I think this drink would be just the thing for us right now!

  • nipponnin July 3, 2013, 9:22 am

    What a gorgeous color! Just beautiful! Are you having fun in Japan?

  • Sonia aka Nasi Lemak Lover July 5, 2013, 11:31 pm

    watermelon juices is perfect for our hot weather here too, and my son Desmond love watermelon juices a lot. Suikawari game sound very fun!

  • Terra July 8, 2013, 8:18 pm

    I think this would be the best summer drink, so refreshing! Then just for fun, add a splash of tequila, rum or vodka….YUM! Delicious, Hugs, Terra

  • Jocelyn (Grandbaby Cakes) July 11, 2013, 9:35 am

    This juice looks absolutely incredible!!

  • Hari Chandana July 13, 2013, 7:22 am

    Very refreshing juice.. awesome clicks as always :)

  • Stephanie July 18, 2013, 3:31 pm

    Watermelon is one of my favorite fruits. I can probably eat a whole one by myself!

  • Alex August 19, 2013, 3:33 pm

    This was really refreshing, but next time I don’t think I’ll add any sugar.

    • Nami August 19, 2013, 9:27 pm

      Thank you so much for trying this recipe Alex! Yes, if the watermelon is already very sweet naturally, you do not need to add sugar or syrup at all. :)

  • Julie B. January 23, 2014, 12:59 pm

    Enjoyed reading this. I went to Japan only once to visit my grandparents with my family, but since I was only five at the time, I don’t remember much. However I do have a photo where we are all sitting around eating watermelon!

    • Nami January 23, 2014, 11:16 pm

      Hi Julie! I hope you get to visit Japan again! Thank you so much for sharing your story. I need to take many pictures when we’re in Japan, so that kids will remember when they grow up… :)
