Can food support sleep, focus, digestion,
or skin condition?
In Japan, the answer is clear: yes -
- as part of everyday eating habits.

Japanese functional food is a unique category of products that combines the simple pleasure of eating with ingredients commonly used to support everyday dietary routines.
These products are not medicines and not traditional supplements. Instead, they are familiar foods such as chocolate, gummies, chewing gum, beverages, and teas, enriched with functional ingredients like GABA, dietary fiber, collagen, probiotics, and plant extracts.
In Japan, functional food is closely connected to daily lifestyle choices, balance, and mindful eating — not to quick fixes or guaranteed results. It reflects a culture where food is designed to fit naturally into everyday life.


What Is Functional Food?
Functional food refers to products that, in addition to their nutritional value, serve an extra role — they are designed to support specific aspects of daily health and well-being as part of an everyday diet.
In Japan, this is neither a passing trend nor a marketing gimmick. Functional food is an officially recognized category, developed over decades through collaboration between scientific research, food manufacturers, and government institutions.
Functional food products:
- are intended for daily consumption,
- do not require a prescription,
- are part of a lifestyle-oriented approach, not medical treatment.

Products Enriched with Additional Ingredients at
WABI-SABI STORE
At WABI-SABI STORE, you can find a wide selection of Japanese food products that are enriched with additional ingredients, such as probiotics, dietary fiber, collagen, GABA, or selected plant extracts. These are everyday food items, commonly enjoyed in Japan as part of a varied and balanced diet.
It is important to emphasize that these products are not medicines and are not intended to treat or prevent any diseases. The presence of specific ingredients does not guarantee any particular effect, and their inclusion in the ingredient list should not be interpreted as a promise of results.
Many Japanese products — including those containing probiotics or lactic acid bacteria — do not carry official functional food labels such as FOSHU or FFC. In such cases, these ingredients are simply part of the recipe rather than a declared health function. This approach reflects the Japanese philosophy of nutrition, which focuses on regularity, variety, and moderation, rather than explicit claims or guaranteed outcomes.
When presenting these products, we focus on providing clear and reliable information about their ingredients, origin, and how they are commonly consumed in Japan, allowing customers to make informed and responsible choices without implying specific health effects.
