Yen & HomeJapan Cost Planner

What does your life cost in Japan?

A grocery cart becomes a monthly plan.

A responsive planning tool for comparing grocery prices, shaping a realistic shopping routine and understanding recurring costs before moving to Japan.

00 / Overview

Plan the routine, not only the purchase.

Yen & Home turns individual prices into a more useful question: what will this way of living cost each month?

The concept connects product comparison with personal context. Household size, meals at home, budget, quantities and shopping frequency all influence the estimate.

The interface uses a bold print-inspired identity to make dense information approachable while keeping every decision visible.

01 / Problem

A price alone cannot explain a life.

People planning a move can find isolated grocery prices, but translating packages, quantities and repeated purchases into a reliable monthly picture requires too much manual work.

Prototype noteCatalog values and currency references demonstrate the model and interaction flow. They are illustrative and should not be read as live financial guidance.
01

Comparable

Package size, total price and unit price appear together so similar items can be evaluated quickly.

02

Personal

Household size, budget and meal routine create a useful starting point without blocking exploration.

03

Monthly

Quantity and purchase frequency turn a one-time cart into an estimate that supports planning.

02 / Product flow

Five steps from uncertainty to a usable estimate.

  1. 01Set household and budget
  2. 02Browse categories or bundles
  3. 03Compare package and unit price
  4. 04Adjust quantity and frequency
  5. 05Review the monthly estimate

Design direction

A practical tool with the warmth of a printed household guide.

The illustration gives the abstract topic of cost planning a human context. Paper textures, offset color and direct typography make the product feel accessible without hiding the functional structure underneath.

03 / Catalog

Dense information, kept easy to compare.

Filtering and sorting stay close to the products, while the quick-comparison panel preserves budget context throughout the catalog.

04 / Starting points

Bundles reduce blank-page decisions.

Solo, couple and routine-based bundles act as editable foundations. They never lock the user into a fixed package.

05 / Visual system

Utility, print texture and Japanese references.

The identity combines the decisiveness of price labels with the familiarity of grocery illustration. Repetition and rough edges make the interface memorable while strict spacing keeps it usable.

06 / Outcome

Make the cost of a routine visible before it becomes a surprise.

The final prototype connects brand character and practical product logic across desktop and mobile. It demonstrates catalog navigation, editable starting points, transparent calculations and a responsive cart experience.
