10-Bai Gayu (10x Rice Porridge for First Foods)
In Japan, nearly every baby's first food is okayu — rice porridge. The tradition goes back centuries: plain, gentle rice porridge is considered the safest and most digestible first food. Japanese pediatricians recommend starting with 10-bai gayu (10 parts water to 1 part rice) at around 5 months, then gradually thickening it as the baby develops. This careful, staged approach to introducing solids is a hallmark of Japanese weaning philosophy, where each texture progression is deliberate and mindful.
The very first food for Japanese babies — a silky smooth rice porridge made with just rice and water. This 10-bai gayu (10:1 water to rice ratio) is the traditional starting point for solids in Japan.
Ingredients
- 2 tablespoons (30g) Japanese short-grain rice
- 1.5 cups (300ml) water
Ingredient Substitutions
Can't find Japanese ingredients? Here are alternatives available at most supermarkets.
- Japanese short-grain rice → Calrose rice (widely available in US), or any short-grain/sushi rice
- If short-grain rice is unavailable, medium-grain rice works but the texture will be slightly less creamy
Instructions
- 01Rinse the rice gently in a fine-mesh sieve until the water runs clear.
- 02Combine rice and water in a small heavy-bottomed pot. Let it soak for 30 minutes if time allows.
- 03Bring to a boil over medium heat, then reduce to the lowest setting. Cover with a lid slightly ajar.
- 04Simmer for 30-40 minutes, stirring occasionally to prevent sticking.
- 05The rice should be completely broken down and the porridge very watery.
- 06Press through a fine sieve or blend until perfectly smooth with no lumps.
- 07Serve 1-2 teaspoons at body temperature for baby's first feeding.
Tips from a Dietitian Mom
- For the very first feeding, make it extra smooth by straining through a tea strainer.
- Japanese moms often make a batch and freeze in ice cube trays — each cube is roughly one portion.
- As a registered dietitian, I recommend starting with just one teaspoon on day one and gradually increasing.
- Use Japanese short-grain rice if possible — it creates a naturally creamier texture than long-grain varieties.
Storage & Freezing
Refrigerate for up to 24 hours. Freeze in ice cube trays for up to 2 weeks. Thaw in the refrigerator or microwave, and always check temperature before serving.

Frequently Asked Questions
- When should I start giving my baby okayu?
- In Japan, pediatricians recommend starting solids around 5-6 months when baby shows signs of readiness: holding head steady, showing interest in food, and loss of the tongue-thrust reflex. Always consult your pediatrician before starting.
- What is the difference between 10-bai gayu and 7-bai gayu?
- 10-bai gayu uses a 10:1 water-to-rice ratio and is very thin — perfect for 5-6 month olds just starting solids. 7-bai gayu (7:1 ratio) is thicker and suitable for 7-8 month olds who have gotten used to eating.
- Can I use a rice cooker to make baby okayu?
- Yes! Many Japanese rice cookers have an okayu setting. Use the same ratio of rice to water. The rice cooker method is very convenient for busy parents.
