Tracked every yen over 10 days in tokyo. Heres exactly how to eat well on ¥2000 daily:

breakfast: konbini onigiri ¥110 + famima coffee ¥150 = ¥260 total. Hotel breakfast buffets at ¥1500+ are highway robbery

lunch: teishoku sets ¥600-800 at places with plastic food displays and salary worker lines in marunouchi business district. Avoid english menus in harajuku tourist zones

dinner: ramen yokocho ¥700-900 or standing bar tachigui gyoza + beer ¥800-1200. Happy hour yakitori ¥100/stick between 17:00-19:00 near jr stations

supermarket hack: bento boxes 50% off after 20:00 at life and summit. Way cheaper than konbini for drinks near shibuya center gai

total savings: ¥8000 over 10 days vs roppongi tourist restaurants. Thats 2 extra days in tokyo right there
