Studying at Fukuoka

My girlfriend (F26) and I (M29) are planning to go to Japan for one year next year (2027).

Initially we wanted to do one whole year of language studying in Tokyo, and do some interstate travelling over weekends. However due to budget constraints, we are now looking to study Japanese (we meet the requirements) at Fukuoka language school for 6 months, Osaka/Tokyo for 3 months and then travel around Japan for 3 months. The main reason why we went this route is to save money during the first half year and spend slightly more on travelling towards the end.

However we're worried that there's not much to do/see while staying in Fukuoka for 6 months. The research we have seen online so far are mostly 3 days travel in Fukuoka, and/or 5 to 7 days around Kyushu.

People who have moved to Japan or have studied in Japan, what are your thoughts? Any advice is much appreciated!

Also, we're not able to work in Japan due to Visa reasons.
