Vliv japonské kultury na přístupy k UX/UI a webdesignu v Japonsku

The goal of this thesis is to synthesise cross-cultural design research into a practical methodological framework — the 5-Layer Localisation Framework (5LLF) — guiding designers in adapting digital interfaces for the Japanese market across five operational layers: Information Architecture, Navigation, Typography, Trust Markers, and Emotional Localisation. This bachelor's thesis examines how Japanese cultural codes, cognitive habits, and linguistic structures shape approaches to UX/UI and web design in Japan, addressing why Japanese digital interfaces diverge so consistently from the Western minimalist standard. Drawing on Hofstede's cultural dimensions and cognitive psychology, including the aquarium perception experiment, the thesis first establishes the theoretical foundations of the cultural determination of design and traces how traditional aesthetic concepts such as Ma, Wabi-sabi, and Kawaii are adapted into digital form. It then presents an empirical heuristic audit of leading Japanese and Western digital platforms — specifically Google, Yahoo! Japan, Rakuten, and Starbucks Japan — demonstrating systematic differences in information architecture, typography, and trust signalling. Building on these findings, Chapter 6 proposes the 5LLF, in which each layer is defined by exact technical specifications, theoretical grounding, empirical evidence from the heuristic audit, and anti-patterns identifying design failures common among Western practitioners. The framework's effectiveness was validated through an expert survey of nineteen UX/UI professionals. The results confirm that cultural empathy in design is not merely a stylistic preference but an operational and commercial requirement for digital products to succeed in the Japanese market.
