Each tool serves a clearly distinct function: listing holidays, getting date details, converting eras, and finding the next holiday. There is no overlap in their purposes.
All tools share the 'jp_' prefix and snake_case, but the pattern is not uniform: 'list_holidays' and 'convert_era' are verb_noun, while 'date_info' and 'next_holiday' are not. Minor deviation from a consistent verb_noun pattern.
Four tools is ideal for the narrow domain of Japanese date and holiday utilities. Each tool is essential and there is no bloat.
The tool set covers the main lifecycle of date queries: retrieving holiday lists, getting detailed date info, converting between calendars, and finding upcoming holidays. There are no obvious gaps for its stated purpose.
